How Much Protein Per Day Bodybuilding: Ultimate Guide for Maximum Gains

Most people grab a pair of dumbbells for curls and presses and never think to pull them off the floor. That's a missed opportunity. A pair of 40s and a patch of floor is enough to learn a proper hip hinge, no barbell or rack required. Picking them up is the easy part. Where lifters get into trouble is everything around it: how deep the dumbbells start, how much the knees bend, and whether you end up feeling it in your hamstrings or your lower back. Below, we go through the form step by step and what each muscle is doing, then how the lift compares with the barbell version. We also cover four variations that fit a home gym. What Is the Dumbbell Deadlift? The dumbbell deadlift is a hip-hinge lift where the weight starts on the floor, and you stand up with it. The weights end up at your sides, not out in front of your shins, and that small change in position affects how the whole lift feels. With no bar to drag up your legs, you don't have to widen your stance or tuck your knees out of the way. Your knees can drift forward a bit more, so the lift leans on the quads somewhat more than a conventional barbell pull does. Hex bar deadlifts work the same way, and the research on them is useful here. A biomechanical study published in the Journal of Strength and Conditioning Research compared straight and hex bar deadlifts at submaximal loads. It found the hex bar moved more of the work to the knee and lowered the demand on the lower back. The study used hex bars, not dumbbells, but the weight sits in a similar place beside the body. That's a big reason dumbbell deadlifts are a friendly starting point for newer lifters. Don't confuse it with the Romanian deadlift, though. The RDL starts from standing, keeps the knees fairly straight, and never lets the weights touch down. The dumbbell deadlift resets on the floor every rep. Dumbbell Deadlift Muscles Worked The dumbbell deadlift trains the whole back side of the body, along with the quads and the muscles that hold the weight in your hands. The glutes and hamstrings drive the hips forward as you stand. The quadriceps help extend the knees off the floor. The erector spinae keep your torso rigid under load, and the lats and upper traps work to hold the dumbbells close to your body. Your forearms and grip muscles are working the whole time, and for most people they’re the first thing to fatigue. Research on deadlift variations gives a more specific picture. A systematic review in PLOS ONE pooled surface EMG data from studies on the deadlift and its variants. It found that hamstring-biased versions, such as the Romanian and stiff-leg deadlift, tended to produce more biceps femoris and semitendinosus activity than the conventional pull, while the sumo stance leaned more heavily on the quadriceps. The takeaway for dumbbell training is that small changes in knee bend and stance can move the emphasis from the quads to the hamstrings, which is exactly what the variations below are for. How to Do the Dumbbell Deadlift with Proper Form Set the dumbbells. Put them on the floor just outside your feet, handles parallel and pointing forward. Find your stance. Feet about hip-width, toes turned out a little. If you look down, the dumbbell handles should sit over the middle of each foot, not out toward your toes. Hinge, then bend. This is where people go wrong, so slow it down. Let the hips travel behind you until your hands are around mid-shin, then bend your knees to get the rest of the way down. If your knees bend first, you're squatting, and the dumbbells will feel like they weigh twice as much. Grip and brace. Palms face in. Squeeze the handles hard, pull your shoulders down away from your ears, and take a big breath into your stomach before you pull. Think of bracing for a punch. Stand. Push the floor away. Your hips and chest should rise at the same speed, with the dumbbells dragging lightly along your thighs the whole way. Lock out. Stand tall, glutes squeezed. Don’t lean back to finish, because that just shifts the stress into your lower back. Lower under control. On the way down, hips go back first again, then the knees bend once the dumbbells clear them. Set the weights down. If you hear a loud bang, that’s your cue to drop the load by 10 or 15 pounds. Starting height deserves its own note. Standard barbell plates put the bar about nine inches off the floor, but plenty of dumbbells sit lower, especially smaller hex heads and adjustable sets. Reaching down that far takes more hip and ankle mobility than many lifters have, and you'll notice it as your lower back curling as the weights touch down. Don't fight it. Put the dumbbells on a pair of bumper plates, or stand on a low step, and you're in a position you can hold with a flat back. You can work down to the floor as your mobility improves. Common Mistakes To Avoid Rounding your lower back at the bottom. It usually sneaks in during the last two reps of a hard set, when the first few looked fine. You won't feel it, so film one set from the side. If it only shows up late, end the set a rep sooner. If it shows up on rep one, the starting position is too low for you, and blocks under the dumbbells are the fix. Starting with your hips too high. When your legs are almost straight before the weights move, you've drifted into a stiff-leg deadlift by accident, and your lower back is doing the job your legs should share. Sit back and down until your shins are close to vertical and your hips are just above knee level. Letting the dumbbells swing out in front. A light pair hides this one. Go up in weight, and you'll feel it right away, since every inch the dumbbells drift from your thighs adds leverage against your lower back. Think about sliding them along your legs like you’re zipping up a tight jacket, with your shoulder blades pinned back. Ignoring your grip. Dumbbells won't let you switch to a mixed or hook grip like a barbell does, so your hands usually fail before your legs do. Chalk is worth keeping in your gym bag. On the heaviest sets, straps are fine. Just keep your warm-up sets strapless so the grip keeps getting stronger. Dumbbell Deadlift Variations Dumbbell Romanian Deadlift The RDL is the version to reach for when your hamstrings are the target. You start standing with the dumbbells in front of your thighs, soften your knees a little, and then push your hips back as far as they'll go. The knees barely change angle from there. The dumbbells slide down your legs until you feel the hamstrings reach their limit, which for most people is somewhere around mid-shin. Go past that point and the movement usually comes from your lower back rounding, not from any extra stretch in the hamstrings. Because the weights never rest on the floor, there's no reset between reps, so the tension stays on the back of your legs from the first rep to the last. Expect to use lighter dumbbells than you would for the standard floor version, since the hamstrings tire out sooner than the quads and glutes do. A slow three-second lowering phase will humble you quickly, and it's a good way to learn where your hamstring range actually ends. Dumbbell Stiff-Leg Deadlift The stiff-leg deadlift is the RDL with the knees locked almost straight. You keep only the faintest bend, just enough that your kneecaps aren't jammed back, and the hips do all the traveling. With the legs that straight, the hamstrings can't borrow help from the quads, so they take the whole stretch. You'll feel it as a pull behind the knees and up into the upper hamstrings, usually much earlier in the descent than you would on an RDL. Some lifters start each rep from the floor, and others stand on a low step so the dumbbells can hang below their feet. Either works, as long as your back stays flat. Plan on using less weight than you'd think. Many lifters drop 20 to 30 percent from their RDL numbers the first time they try this, and the stretch is hard enough that it's easy to feel the work in your lower back before your hamstrings. That's your signal to stop the rep right there, even if the dumbbells are still a few inches from the floor. Reaching the floor isn't the goal. A flat back and a strong hamstring stretch are. Dumbbell Sumo Deadlift Stand with your feet well outside shoulder width and your toes turned out around 30 to 45 degrees. Then hold one dumbbell vertically in both hands, with your palms cupped under the top end like you're holding a goblet, and let it hang between your legs. Because the weight hangs right under your torso, you can sit your hips down and keep your chest tall. Your shins end up nearly vertical, and the lower back gets off easy compared with a standard pull. A lot of lifters find this the most natural floor pull to learn first, partly because there’s only one dumbbell to set up. The catch is the stance itself. A wide sumo position needs more hip and inner-thigh flexibility than people expect, and if your knees cave in as you stand, the stance is too wide or the toes aren't turned out enough. Push your knees out over your toes the whole way up. The quads and inner thighs tend to carry more of the work here than on the standard version, which fits the EMG pattern we covered earlier. If you want to see how the same stance plays out with a barbell, our sumo vs conventional deadlift article breaks it down. Single-Leg Dumbbell Deadlift Grab one dumbbell in the hand opposite your standing leg. Say you're balancing on your right foot: the dumbbell goes in your left hand. From there, you tip forward from the hips while the left leg floats back, and the dumbbell lowers toward the floor next to your right foot. Everything moves as one piece, a bit like a seesaw tipping over. It helps to train barefoot or in flat shoes, since a thick running shoe adds wobble you don't need. Most people find their hips twisting open the first few times they try this. If your back-leg side starts rolling up toward the ceiling, you've gone lower than your standing hip can control, so cut the range short and build it back up over a few weeks. A wall within fingertip reach is a perfectly good crutch early on. Dumbbell Deadlift vs Barbell Deadlift Exercise Dumbbell Deadlift Barbell Deadlift Load ceiling Limited by your heaviest dumbbells and grip Much higher, limited mainly by plates Starting height Often lower than a barbell, can be raised on blocks Fixed by plate diameter Load position At your sides In front of the shins Feel A bit more quad-dominant, easier to learn More posterior-chain focus Grip Neutral, no mixed grip needed Overhand, mixed, or hook Space and cost Minimal Needs a bar, plates, and floor protection Best for Beginners, high-rep work, limited equipment Maximal strength and heavy progression Neither lift replaces the other. The dumbbell deadlift is a very good way to learn the hinge, build work capacity, and train the posterior chain when you don't have a barbell. If your goal is to move truly heavy weight, the barbell deadlift is the better long-term tool. Our Dumbbell Deadlift vs Barbell Deadlift comparison guide pick up from there. How to Program It at Home Gym Most home gyms have one real limit, and it's the top of the dumbbell rack. So the setup comes first, because a lift you can't do safely on your floor won't get programmed for long. Put down rubber flooring or a deadlift platform before anything else. Dumbbells are loud on concrete and chip tile. Hex or octagonal dumbbells are worth considering, since a round dumbbell rolls the moment you set it down and your starting position changes. And try not to drop adjustable dumbbells from lockout. The plates and collars can loosen a little each time, and you'll find out at the worst moment. The table below lays out a starting point for each goal. These are common coaching ranges, so adjust them to how your back and grip respond. Goal Sets x Reps Frequency Tempo and notes Learning the hinge 3 x 8 to 10 2x per week 2-second lowering, stop each rep with a flat back Building muscle 3 to 4 x 8 to 12 1 to 2x per week 3-second lowering, 1 to 2 reps left in reserve Strength with limited weight 4 x 5 to 6 1x per week Pause for a second just below the knee, go to the floor on blocks if needed Posterior-chain finisher 2 to 3 x 12 to 15 After squats or presses Light weight, focus on the glute squeeze at the top Once the dumbbells start feeling light, you don't need heavier ones to keep progressing. Slow the lowering phase to three seconds, add a one-second pause just below the knee, or stand on a low platform so the weights travel farther. Moving to the single-leg version is the biggest jump, since it roughly halves what you can use. Any of these keeps the lift hard well after you've run out of dumbbell weight. FAQs 1. Are deadlifts with dumbbells effective? They are. A dumbbell deadlift hits the same muscles as the barbell version: glutes, hamstrings, quads, and back. It’s also easier to learn, since the weights hang at your sides and you don't have to worry about a bar scraping your shins. The catch shows up once you get strong. Eventually your heaviest pair stops being a challenge, and at that point you’re stuck with slower tempos and single-leg work or a trip to the barbell rack. 2. What is a good weight for a dumbbell deadlift for a beginner? Go lighter than you think you need to. A lot of first-timers land somewhere around 15 to 30 pounds in each hand, but that depends on your size and training background, so don't take it as a rule. Try 10 reps. Did your back stay flat, and did you finish feeling like two or three more were possible? Then you picked well. Rounding or a failing grip means grab a lighter pair. 3. Which is harder, RDL or SLDL? Most people find the stiff-leg version harder. Straight knees mean your hamstrings are on the hook for the entire stretch, and you’ll hit your limit sooner than you would on an RDL. Tight hamstrings? Stick with the RDL for a few weeks first, then try stiff-leg once you can move through more range. 4. Can I just do RDLs instead of deadlifts? Sure, plenty of lifters do. Just know they're not identical. The RDL is mostly a hamstring and glute exercise, while a floor deadlift adds more quad work and makes you start every rep from a dead stop. If you mainly want bigger hamstrings and glutes, RDLs alone can get you there. If you want a full-body pull, it’s worth keeping a floor version in the mix. 5. How many times a week should I deadlift? Once or twice is plenty for most people. Your lower back and grip take a beating from this lift, and a hard session can hang around for a couple of days. Many lifters do well with one heavy day and one lighter day, say dumbbell deadlifts on Monday and RDLs or single-leg work on Thursday. If you're still sore or beat up from last time, give yourself an extra day. References 1.

The dumbbell fly looks easy. Lie back, open your arms, and bring them together. But it's one of those moves that's simple to get wrong, and a lot of people do. The weights creep up, the elbows start bending, and before you know it, you're doing a sloppy press. Below, we'll go through proper form for the dumbbell chest fly, the mistakes that trip people up most, and four ways to do it: flat, incline, decline, and on the floor. What Is a Dumbbell Fly? The dumbbell fly is an isolation exercise for your chest. You lie on a bench with a dumbbell in each hand, swing your arms out to the sides in a wide arc, then bring them back together over your chest. Your elbows stay slightly bent the whole time, so all the movement comes from the shoulder. That's the big difference from a press. You're not pushing anything away from you, so your triceps get a break, and your chest does the work of pulling your arms together. Picture hugging a big barrel: arms open, stretch across the chest, then squeeze back to the middle. You'll also see it called a dumbbell chest fly or a dumbbell pec fly. Same exercise, different name. You can do it flat, on an incline or decline bench, or lying on the floor. Most people add it after their heavy pressing for a little extra chest work, and we'll get to that below. What Muscles Does the Dumbbell Fly Work? Mostly your chest. It works the pectoralis major, the big fan-shaped muscle that runs from your collarbone and breastbone out to your upper arm. When that muscle contracts, it pulls your arm across your body, which is exactly what you're doing when you bring the dumbbells back together over your chest. Your front delts help out, but they're not the star here. In a 2020 study, 17 trained men did six-rep-max sets of the fly and the barbell bench press. The bench press produced about 25% more front delt activation and about 75% more triceps activation. That makes sense: your elbows barely move during a fly, so your triceps aren't pushing anything. They mostly just help hold your arms steady. The same study found something less obvious. Your biceps worked about 76% harder on the fly than on the bench press. They don't curl anything, but they keep your elbows locked at the same angle while the weights pull your arms apart. If your biceps feel pumped after a set, that's why. Here's the part that helps most with form. The researchers also looked at the rep in slices. As the men pushed the dumbbells back up, chest activation matched the bench press through the bottom and middle of the rep, then fell behind near the top. The authors tie that to leverage: the dumbbells hang far from your body at the bottom, which makes the weight feel heavy, and as your arms come together, the leverage shortens, and the load fades. So the stretch at the bottom is where the fly earns its keep, and we'll cover how to set that up next. How to Do the Dumbbell Fly (Step by Step) Set up on the bench. Sit with the dumbbells resting on your thighs, then lie back and use your knees to help kick the weights up. Plant your feet flat on the floor. Set your shoulders. Pull your shoulder blades back and down, as if you're tucking them into your back pockets. Keep them there for the whole set. Start with the weights over your chest. Press the dumbbells up with your palms facing each other, elbows soft, not locked. Open your arms. Lower the dumbbells out to the sides in a wide arc. Keep a slight, fixed bend in your elbows and let your chest, not your arms, guide the movement. Stop at a comfortable stretch. Lower until your upper arms are about parallel to the floor, or slightly above, as long as you feel a stretch across your chest without any pinch in the front of your shoulder. Bring them back together. Squeeze your chest to draw the dumbbells up along the same arc until they nearly touch above your chest. Pause briefly, then repeat. A good tempo is about two seconds on the way down and one on the way up. Breathe in as you lower, and out as you squeeze up. Elbow angle is the detail most people miss. In the study we mentioned earlier, lifters held about 150 to 160 degrees of elbow bend at the bottom of the rep, and any attempt where the elbows bent further was thrown out. You don't need a protractor. Just picture a relaxed, slightly rounded arm that stays the same shape from the top of the rep to the bottom. The moment your elbows start folding, you've drifted into a press. Dumbbell Fly Form: Common Mistakes to Avoid If your flys feel off, check the weight first. It's behind most of what goes wrong. Too much weight. Watch your elbows. When the dumbbells get heavy, they bend and sink a little more each rep, and you end up pressing the weights back up instead of squeezing them together. By rep eight, your arms should look just like they did on rep one. If they don't, grab lighter dumbbells. Locking your elbows straight. Going the other way doesn't help, either. With fully straight arms, the dumbbells act like long levers, which is rough on your elbows and takes your chest out of the movement. Keep a soft bend, like you're holding a beach ball. Going too deep and letting your shoulders roll. These two usually show up together. Picture your last couple of reps, when you're tired and reaching for a bigger stretch. Your elbows sink below the bench, your shoulder blades slide off the pad, and suddenly the front of your shoulder is doing the work. A few inches too far and the stretch stops helping your chest. Stop while your chest still feels in charge, and keep your upper back planted on the bench the whole set. Dropping the weights too fast. The stretch at the bottom only pays off if you're in control when you get there. Free-falling through the first half of the rep wastes it. Take a full two seconds on the way down. Bent wrists. If the dumbbells end up resting on the backs of your hands, your forearms are carrying the load instead of your chest. Keep your wrists straight and lined up with your forearms. Dumbbell Fly Variations Flat Dumbbell Fly The flat fly is the one to learn first. It's the version we walked through in the steps above, and with no bench angle to think about, you can put all your attention on keeping the same soft elbow bend from the first inch to the last. It works your chest as a whole, so it's a safe pick if you only have room for one fly in your routine. Incline Dumbbell Fly Set the bench to a low incline, around 30 degrees, and run the same fly. It's the version most lifters reach for when they want to hit the upper chest, but the research doesn't really back that up. In a study of 17 active men, upper chest activity was about the same on flat and incline flys. The middle chest actually worked harder on the flat bench, while the incline shifted more of the work to the front delts and the serratus anterior, the muscle along your ribs that helps control your shoulder blade. That doesn't make the incline fly a bad choice. It's a good change of pace, and some lifters just like how it feels. Just keep the bench low, and don't expect it to replace the flat fly. Decline Dumbbell Fly Flip the bench the other way, and you get the decline fly. Set the bench to a small decline, tuck your feet under the pads, and run the same fly you'd do flat. Because your torso tilts head-down, the dumbbells travel along a slightly different line, and a lot of lifters say they feel it lower on the chest. Research on the decline fly specifically is thin, so treat that as a popular gym take, not a proven fact. Getting the dumbbells into position is the awkward part. Sit up with them on your thighs, lie back, and kick them up one at a time. If that feels sketchy, ask for a hand. And since your head sits lower than your hips, skip this one if it makes you dizzy or lightheaded. Dumbbell Floor Fly The floor fly is the simplest version to set up. Lie on your back on a mat, knees bent and feet flat, with a dumbbell in each hand. Run the same fly, and when the backs of your upper arms touch the floor, that's your stopping point. Pause for a beat there, then bring the weights back up. The floor does the range-of-motion work for you. You can't sink past parallel even if you want to, which takes the "how deep is too deep?" question off the table. That's handy if you're new to flys or your shoulders get cranky at the bottom of a bench fly. It's also the obvious pick if you don’t own a bench yet. You do give up some stretch, since the floor cuts the range short. You can make up for it by pausing on the floor for a second, then squeezing hard at the top. One more tip: let your elbows rest lightly on the floor; don't drop them onto it, or you'll lose tension, and the next rep will start from a dead stop. Dumbbell Fly vs. Cable Fly vs. Dumbbell Press Exercise Dumbbell Fly Cable Fly Dumbbell Press Type Isolation Isolation Compound Where it's hardest Bottom (stretched position) Throughout the range Throughout, shifting with the arms Equipment Dumbbells + bench Cable station Dumbbells + bench Best for Chest stretch, a lighter finishing movement Steady chest tension Heavy loading, overall size and strength The fly has a quirk that's worth understanding. Because the dumbbells hang away from your body at the bottom, the resistance is greatest there and fades as your arms come together at the top. Cables, on the other hand, keep pulling on you all the way through. If you want tension at the top of the rep, our cable chest fly guide is the better fit. The fly also isn't a replacement for pressing. In a study of 12 college-age lifters, the dumbbell fly had significantly less relative time of muscle activation than the barbell or dumbbell bench press, leading the authors to suggest the fly works best as an auxiliary lift while presses can serve as the main chest movement. That matches how most good programs use it: press first, fly second. How to Choose the Right Weight and Reps Go lighter than you think. In a study of trained men, the average six-rep max on the dumbbell fly was about 40 kg (roughly 90 lb) total, compared to about 88 kg (roughly 195 lb) on the barbell bench press. That's less than half, and it's normal. The fly is a long-lever move, so the same effort moves a lot less weight. Here's a simple way to set it up: Goal Reps Sets How the weight should feel Build muscle 8 to 15 2 to 4 The last two reps are tough, but your elbow bend and shoulder position match your first rep Learn the movement 10 to 15 2 Light enough that you can pause at the bottom and control every inch Easy on the shoulders 12 to 15 2 Very light, ideally on the floor so the stretch has a built-in stopping point Finisher after pressing 12 to 20 2 to 3 Light to moderate, with a good squeeze at the top A few rules go with the table: Do flys after your presses. Bench press or dumbbell press first, when you're fresh and can lift heavy. Flys come after. Drop the weight when your form breaks. If your elbows start bending more or your shoulders roll forward, the set is over or the weight is too heavy. Stick to moderate-to-high reps. The fly works better for 8 to 15 reps than for heavy, low-rep sets. Range of motion matters too. A 2023 meta-analysis found that a full or long range of motion tends to help muscle size and strength overall, and that partial reps at long muscle lengths may be a useful alternative. For the fly, that doesn't mean forcing yourself deeper than your shoulders allow. It just means don't cut the stretch short out of habit. Use the full range you can control. FAQs 1. What are dumbbell flys good for? They isolate your chest and give it a good stretch. Since your triceps barely work, you can add chest volume after your presses without extra arm fatigue. They also make a solid finisher at the end of chest day. 2. How heavy should you go on dumbbell flys? Lighter than you'd think. Pick a weight you can control for 8 to 15 reps without your elbows bending more as you tire. Most people end up using about half of what they'd use for dumbbell presses, or less. If your form slips, drop the weight. 3. Why can't I feel dumbbell flys in my chest? Most often, the weight is too heavy. Your elbows bend, and the rep turns into a press. Pull your shoulder blades back and down, slow the lowering phase to about two seconds, and focus on squeezing your chest to bring your arms together. Feeling your biceps a little is normal, since they help hold your elbows steady. 4. Should dumbbell flys be done flat or incline? Flat is the better default for your chest. Incline flys mostly shift extra work to your front delts instead of your upper chest. Use the incline for variety if you like how it feels, and keep the angle low. 5. Are dumbbell flys better than bench press? No. The bench press works your chest harder and lets you lift much heavier. Do your presses first, then use flys for extra stretch and isolation.

Most lifters have done a dumbbell lateral raise. Far fewer get much out of it. The weights run too heavy, the traps end up doing half the work, and the side delts barely get involved. This guide shows how to do the lift properly and what the research says about where the load actually goes. It also covers how to fit it into a home gym. What Is a Dumbbell Lateral Raise? The dumbbell lateral raise is a single-joint shoulder exercise. You hold a dumbbell in each hand and lift your arms out to the sides until they're about level with the floor. Your middle deltoid does most of the work. That's the part of the shoulder that gives it width. You may also see this lift called the dumbbell side lateral raise. Since nothing else moves, it counts as an isolation exercise. In a shoulder press, your triceps and chest help out, so bigger muscles can share the load. Here the side delt is on its own, which is why light weights feel hard. It's also one of the easier shoulder exercises to set up at home. All you need is a pair of dumbbells and a little floor space. There's no bar over your head and no need for a spotter, so you can train hard on your own without much risk of getting pinned. Beginners can learn the pattern with a few pounds, and advanced lifters still use it for high-rep work at the end of a shoulder session. Muscles Worked by the Dumbbell Lateral Raise The medial deltoid does most of the work. It's the middle slice of the shoulder, sitting on the outside of the joint, and it's what makes your shoulders look wide from the front. Researchers who tested thirteen resistance-trained men found the lateral raise pushed it to about 30% of maximal voluntary contraction. The overhead press came in at roughly 28%, so basically a tie. The bench press and dumbbell fly barely touched it, at 5% and 3%. How you perform the rep matters, though. A 2020 study of ten competitive bodybuilders showed the medial delt fired hardest with a neutral grip and a mostly straight arm. Bend the elbow a lot or swap in a front raise, and activity fell off. Turn the arm inward so the front of the dumbbell dips, and the load shifts around: the rear delt, upper traps, and triceps all worked harder. A few other muscles pitch in. The front and rear delts help the whole way up, and the supraspinatus, a small rotator cuff muscle, gets the arm moving in the first few degrees. Your upper traps join as your arms near shoulder height. When they take over, you'll see a shrug, and that's the most common way people steal reps from their side delts. How to Do the Dumbbell Lateral Raise with Proper Form Stand tall with your feet about hip-width apart. If you tend to sway, use a slight split stance. Hold a dumbbell in each hand at your sides, palms facing your thighs. Brace your core and pull your shoulder blades down and back. Hold that position for the whole set. Keep a small bend in your elbows and lock that angle in. It shouldn’t change between your first rep and your last. Breathe out and sweep the dumbbells out and a touch forward. Lead with your elbows. Picture pushing your hands toward the walls instead of lifting them toward the ceiling. Many people find a path a few inches in front of the strict side line easier on the joint. Stop when your arms are about parallel to the floor, with your wrists level with or a little below your elbows. If your hands climb above your elbows, the front delts and traps start taking over. Breathe in and lower the weights over two to three seconds. Stop just before they touch your legs so the tension stays on. How high you go matters for your shoulder, too. Researchers who studied 77 men, in a paper from the Journal of Strength and Conditioning Research, linked signs of subacromial impingement to lateral raises done above 90 degrees. The men who trained their external rotators showed those signs less often. So shoulder height is a good place to stop. Your hands matter at the top of the rep. Keep your thumbs about level with your pinkies. ACE adds a small tweak: once your arms pass roughly 60 to 70 degrees, turn your thumbs up just a little, which can ease pinching in the joint. Don't go the other way. Tipping the front of the dumbbell down moved the work onto the rear delts and traps in the 2020 bodybuilder study. Finally, pick a weight you can actually control. If your hips have to kick to get the dumbbells up, go lighter. Most people do better with less weight than they expect, and being able to add just a couple of pounds at a time makes that much easier to manage. Common Mistakes To Avoid Swinging the weights. If your torso rocks back or your knees bounce as the dumbbells go up, momentum is doing the lifting. Film a set from the side and you'll spot it right away. Your body should barely move from the first rep to the last. Shrugging. Near the top of the lift, your traps want to jump in, and before you know it your shoulders are up around your ears. Pull your shoulder blades down and keep your neck long. When your traps burn more than your side delts, the dumbbells are probably too heavy for now. Letting the elbows sag. As you tire, the elbows tend to bend more and more, and the lift turns into a short forearm swing. Keep the same soft bend from the first rep to the last, with your elbows traveling up first and your hands a step behind. Locking the elbows straight. The opposite problem can bother the joint. A small, steady bend feels better and still keeps the work on the side delt. Dropping the weights. Letting the dumbbells fall in a second or less throws away much of the rep's value, since the lowering phase is where the side delts work while they lengthen. Count two or three seconds on the way down. It feels painfully slow at first, and you'll likely need lighter dumbbells to do it. That's a good trade. Dumbbell Lateral Raise Variations Seated Dumbbell Lateral Raise Park yourself on the end of a weight bench with your back straight and both feet flat on the floor. The movement is the same as the standing version. The difference is that your legs and hips can't help, so cheating gets a lot harder. You'll probably use lighter dumbbells, and that's fine. If swinging is your problem, this is the easiest fix. Keep the dumbbells at your sides to start, and don't lean back when the set gets tough. Leaning back is just swinging while seated. This one is great for a home gym because all you need is a bench. The fixed seat also makes it obvious when your form starts to slip. Drop the weight a bit from your standing sets, then work back up. Leaning (Single-Arm) Lateral Raise Hold on to a rack upright or the side of a machine with one hand, and raise a dumbbell with the other. How you lean changes where the set feels hardest. Press your hip into the support, and the bottom of the rep feels heaviest, with a nice stretch in the side delt. Walk your feet out and let your body hang away from the support, and now the top of the rep is the tough part. Try both and keep the one you can control best. Start with your weaker arm, then match the same reps with your stronger one. In a home gym, the upright of a power rack makes a handy anchor. Don't lean too far, though. A big tilt changes the path of the dumbbell, and you'll spend the set trying not to tip over. Cable Lateral Raise With a dumbbell, the bottom of the rep is almost free. A cable machine keeps pulling on the muscle there. Set the pulley low and turn so you're standing sideways to the stack. Take the handle with your far hand, then sweep it across your body and out to the side, with the same soft bend in your elbow. Keep the weight light and the reps slow. Stand far enough back that the cable pulls across your body at the start. Don't let your torso sway as you lift. Go light at first. Cable lateral raises feel harder than the numbers on the stack suggest, so being able to add weight in small steps really helps. Plenty of lifters save this version for the end of a shoulder day. By then the heavy lifts are behind you, and a few more tough reps keep the side delt working. Incline Lateral Raise Adjust a bench to a gentle slope, around 30 degrees, then lie on it sideways so your head and upper body are supported. Your top arm hangs in front of you with a dumbbell in hand. Lift it out and up until your arm lines up with your shoulder, then lower it slowly. Don't let it settle at the bottom. Switch sides when the set is done. There are two reasons people like this one. First, the bench holds your body in place, so there's nothing to swing or rock. Second, the weight feels different. Instead of going easy at the bottom, it stays awkward right from the start of the rep, and many people feel it more in the lower part of the range. Grab lighter dumbbells than you use standing. Your first session is basically a trial run. How to Program It in Your Home Gym Lateral raises work best with light weights and clean reps. If your hips start to kick, the dumbbells are too heavy. Side delts recover fast, so you can train them two or three times a week. If you also press that day, do the presses first. The table below has starting points by experience level. Experience level Weight per hand Reps per set Sets per session Sessions per week Beginner 5 to 10 lb 12 to 15 2 to 3 2 Intermediate 10 to 20 lb 10 to 15 3 to 4 2 to 3 Advanced 20 lb and up 8 to 15 3 to 4 2 to 3 Don't treat these numbers as fixed. Your size, your training history, and how slowly you lower the dumbbells will all move the target. Keep adjusting until the final reps burn and your torso stays quiet. To move forward, add a rep or two each session. When you top out the rep range, go up in weight, but only a little. Jumping from 10 to 15 pounds is a 50% increase, and even 20 to 25 is 25% more. That's usually where the swinging starts. If you're going to spend money on one thing, buy dumbbells that climb in 2.5 or 5 lb steps, or an adjustable set. The rest of the setup is simple. A stable bench like the Major Fitness AH64 covers the seated version, and you'll want one with an adjustable back if you plan to try the incline raise. If you prefer cables, the built-in pulley system on the Major Fitness B52 series and B17 lets you set the handle low and run cable lateral raises without buying anything extra. Leave about an arm's width of clear space on each side so you can move freely. FAQs 1. Do dumbbell lateral raises work? Yes, as long as you treat them as a precision lift instead of a heavy one. Researchers tested thirteen trained men and found the lateral raise lit up the side delt about as much as the shoulder press did. Bench press and dumbbell flys hardly touched it. You still have to add reps or weight over the weeks if you want the results to keep coming. 2. Is 20 lb lateral raise good? For most people, yes. A strict 20 lb dumbbell in each hand is a solid lateral raise for many men and a very heavy one for most women and beginners. The number matters less than how the rep looks. If your torso stays still, your shoulders stay down, and you can lower the weights slowly, 20 lb is a good load. If you're rocking to get it up, it's too heavy for now, no matter how impressive the number sounds. 3. What is considered heavy for lateral raises? Heavy is whatever weight starts to break your form. Because the side delts are small and the dumbbells hang far from the shoulder joint, even modest loads feel hard. As a rough guide, anything you can't lift for about 8 clean reps without swinging is heavy for this exercise. The table in the programming section above gives ballpark starting weights by experience level. 4. Can I do lateral raises every day? You can, but most people don't need to. Side delts bounce back quickly, so two to four sessions a week is plenty for most lifters. Doing them every day gives your shoulders very little downtime, and sore, cranky joints are a common reason people end up on the sidelines. Want more volume? Split it into smaller doses across the week and take a day or two fully off. 5. Is it better to lean in or out for lateral raises? Neither is better. They just make different parts of the rep hard. Leaning in, with your hip against a rack, makes the bottom of the rep harder and gives the muscle a deeper stretch. When you lean out and step your feet away from the rack, the top of the rep gets harder instead. If you want more work at the bottom, go with lean-in. If the top of the rep feels too easy, try lean-out. For regular two-arm raises, just stand tall. Tipping forward turns the exercise into a rear delt raise. References 1. International Journal of Environmental Research and Public Health – An Electromyographic Analysis of Lateral Raise Variations and Frontal Raise in Competitive Bodybuilders. Ten competitive bodybuilders did lateral raises with different arm rotations. The medial deltoid worked hardest with a neutral grip, and turning the arm inward shifted more of the load to the rear delt, upper traps, and triceps. 2. Journal of Strength and Conditioning Research – Characteristics of Shoulder Impingement in the Recreational Weight-Training Population. Among 77 men, signs of subacromial impingement were linked to lateral raises above 90 degrees. Men who trained their external rotators showed those signs less often. 3. Journal of Human Kinetics – Different Shoulder Exercises Affect the Activation of Deltoid Portions in Resistance-Trained Individuals. In this study of thirteen trained men, the lateral raise took the medial deltoid to roughly 30% of maximal voluntary contraction. That landed close to the shoulder press and well above the bench press and dumbbell fly.
