Major Fitness Heritage Series B17 Flying Fortress All-In-One Functional Trainer with Smith Machine

Love this thing!!! 12/10 would recommend to a friend! Hopefully this commercial grade rack will last me a lifetime. I just hope they sell individual parts for it as things like cables fray and pulleys wear and things like that. But man this thing is awesome. Love the product and will for sure purchase more Major Fitness products moving forward!

I absolutely love my Major Fitness B17 (Flying Fortress)! It is hands down the best investment I have ever made for my home gym setup.The build quality is incredible, and it is an absolute beast for workouts. Having a high-quality all-in-one system right in my house saves me so much time and gives me everything I need for serious training. It functions beautifully, looks amazing, and outperforms any expectations I had.

Major Fitness B17 Review I wasn’t entirely certain I was going to write a review on this, but after receiving this set, I felt compelled to give my honest opinion, on both Major Fitness as well as this rack setup. I’ll preface that I did quite a lot of research before committing to purchasing the B17, I had gone back and forth between a few different competing racks, some of which were a 3x3” vs the offering of this rack where there are 2x3” posts. The real struggle that I had was the debate on attachments and compatibility with the 2x3” posts, I think I had pretty legitimate concerns, but after spending a ton of time in this research, I came to the conclusion that this isn’t a massive concern, there’s not a whole lot that I can’t do with this system and in my experience it does everything very well. Getting myself to spend $4000 on a piece of exercise equipment was no easy task, but I’ll admit I am glad that I made this purchase and it has absolutely transformed my garage gym from a setup with a fairly limited functional trainer, to the feeling that there is no exercise I cannot execute on this platform. I’ll add, I also purchased the AH64 bench, the 750lb capacity barbell and also threw in the leg extension attachment, which is in itself such an amazing attachment. I do feel like I’ll write separate reviews on these as well, the value is definitely there. On to the B17 in detail and the entire process with Major Fitness. I placed my order on a Tuesday and received the rack exactly a week later, I was hesitant, I had read a few issues with QC, and some subpar packaging, I can honestly say that I did not share that experience. It was pretty exiting, delivery truck showed up with this huge, awesome palletized wooden box, it made me feel like kid on Christmas, I just had to wait to even start unpacking and building it. In the unpacking process everything was packed neatly, securely and damage free, but I will say the number of parts, pieces and hardware is absolutely overwhelming. I took the time to pull every nut and bolt out and inventory everything before even beginning assembly, this took up a ton of room, so if you take this approach, have plenty of room available, and in my case try to steer the kids towards other activities. I’d say this process took me about 1.5-2 hours, it probably wasn’t necessary but I wanted to make sure if anything was missing, I could reach out to Major quickly and get that process started. Onto the assembly. I know many individuals in my research suggested to watch the YouTube videos, but I opted for the instructions and they were detailed and well drawn out. The biggest piece of advice to not skimp over is to NOT tighten any bolts past finger tight until the end or near the end, I waited until the very end to tighten anything, this made it so much easier than other equipment I’ve assembled in the past where I end up loosening bolts anyways. Be absolutely prepared for this assembly to take a ton of time, I did this completely solo and I’d say overall it took me around 8-9 hours to complete, there were a couple of challenging areas (primarily attaching the pegboard) that was really hard to do on my own, but I was able to prevail with a little creativity, certain steps with 2 people would have simplified things, but it is doable without. With everything tightened up at the end, I have to say this machine is incredibly stout. Any doubts I had about the 2x3” posts are unfounded and proven wrong. I plan on leaving this unbolted from the floor and I have zero concerns with tipping even with dropping weight on the front spotter arms. Getting into the usage of this machine, I have to say I’m blown away on how smooth, clean and refined it all feels. The smith bar feels incredible, the cables smooth on both the 1:1 and 2:1 ratio, which also was a big selling point and leaves so much room for growth when combining it with the plate add on capability. Swapping between the various attachments feels great and is really simple and straight forward, I feel like I have a commercial piece of gym equipment in my garage. Each of the attachments are high quality and are well designed, the pegboard is such a cool feature for storage and holds the majority of attachments with the exception of the leg extension and spotter arms, but everything else fits very well and looks incredible. I am considering the only 2 attachments I don’t have which is the lever arms and the shoulder lateral raise, just based on the quality I’ve experienced up to this point. If you’re in the market for a high end piece of equipment, I’d highly recommend this setup, this has exceeded my expectations from a quality and capability perspective and I look forward to having this machine as the centerpiece of my garage gym for many years to come. So much more to learn and experience, have yet to unlock every possible workout I can do on this machine.

We have a small space for our home gym, yet the B17 works PERFECTLY for our space! I am able to get every kind of workout you can think of done with it! All of the accessories are easy to add on and take off. I LOVE IT!

Thing works great. Rock solid half rack. Pulley system is nice. Wish the pull-up system had different grips (straight bar with angles). No complaints

I love this machine and there seems to be very little limit to what you can do with it. I am very happy with the decision to purchase it, if you’re hesitating, stop. After arrival we inventoried all pieces, some hardware fasteners are preinstalled and need to be identified on the inventory sheet. After reviewing the installation process, the instructions are precise but the pictures could be better. There is a video QR code on the back of the instructions which is very helpful; don’t ignore it. Inspect all pieces before installation, especially the CE cables at the tensioner bolt; ensure the ends are properly crimped or they will fail, take pictures if doubtful and test their function under light loads and gradually increase them. Every page is headed with the warning to not tighten connections until entire process is complete, pay attention to that and finish tightening all connections just prior to your first workout at as a final step. The B17 goes together rather simply, but 2 people is a must. All fasteners come packaged on large sheets and are easy to identify, you will need 2 x 17mm sockets and wrenches; we used a clutched drill driver to speed things along without over torquing and tightening too much before completing the build. When installing the weight stack, ensure the plastic spacer rings are always facing up when sliding them onto the guides. After two weeks of using the machine, I am slipping into a good routine and falling more and more in love with it. The range of motion on the pulleys make changing positions easy and seamless. I am having a hard time finding an exercise this machine cannot handle; with proper attachments of course. I purchased the lever arms and, to be honest, I am still learning how to incorporate them. Upon attaching them and placing the bench in the middle, I found they are too wide to use as a substitute for bench pressing; however, as I stated, I may just not be experienced enough with using them. They have a small eyebolt attachment to use with cables, but they seem better fit to use with free weights, which they are equipped to accommodate. The Smith machine works perfect and the bearings provide a smooth workout experience. The pulley systems are very well thought out, and the ability to switch from 2:1 to 1:1 ratios are a game changer. The updated top arms are great for lat pull downs and it comes with one bar, but order the Lat pulldown package with the B17; that is something I wish I’d done, along with the shoulder lateral raise arms. I am researching the leg press attachment as well, but I’m starting to wish I had went ahead and included it as well. Overall, after spending 4 years in gyms and paying memberships, waiting for machines or weights to open up, questionable cleanliness, and overcrowding, this has been a godsend. I live this machine, and have zero buyers remorse. The 4 stars are due to some questionable QA/QC issues like the faulty CE cable (that title will make sense upon building) unfinished surfaces on the smith machine bar, confusing inventory descriptions, and other minor experiences. However, the FB account is monitored and when DM’d they respond with helpful advice very quickly. Customer service has been very responsive and usually will address any concerns within 24 hours of your email. That being said, and I may be off base, but after a $5k investment, I would like to have been compensated in some way for the blemished smith bar, and other QA/QC shortcomings. Stop hesitating, make your purchase and start enjoying your home gym.

The B17 is a complete set up for any home fitness area!! It is easy to use. Cables move as they should. Limitless options for exercises. Was somewhat intimidating to assemble due to having so many items but we'll worth it.

My husband and I have been using the B17 for the last few weeks and absolutely love it so far - this thing is a beast!! (Ignore the unfinished walls we’re still working on finishing converting our garage into a home gym - these are the tractor supply rubber stall floor mats with diamond plate texture for anyone who is curious). Thoughts on the assembly process… 1. I pre-ordered the machine on November 24th. Around December 5th (after the presale was over) I emailed their customer support team inquiring on when they would ship my machine and they told me 1-3 business days from our communication. Within 2 business days I had a tracking number. That tracking number was through DHL and did not accurately update. I had a shipper text me directly from their phone confirming delivery for 2 days later. It did require me to be home for a signature. 2. The pallet packing was nice so everything could arrive at one time, however I feel the labeling and organization on how they boxed the parts could’ve been a little better. In the end I found everything I needed to, but would’ve been easier if they boxed it by each step and labeled accordingly. Also, getting rid of a pallet box now is going to be annoying 😅 3. I was missing the part # 1 flat washers (x210 M10 24D) which are a main component needed to assemble. It seems they accidentally gave me 2x #6 parts instead of the #1 part. MF customer support was very responsive and worked with me to correct this pretty quickly. 4. Speaking of parts list, part #s 7 & 11 come PRE-INSTALLED on some of the other parts (ex: the pulleys bolts, washers, and lock nuts). There’s small text at the top of the parts list that states this but I missed it at first. 5. For anyone who can’t find, or accidentally threw out, their parts list or assembly guide, here are the online links to access them: Parts List: https://cdn.shopify.com/s/files/1/0580/4484/2041/files/B17_Product_List_a.pdf?v=1763104306 Video Assembly Guide: https://www.majorfitness.com/pages/major-fitness-installation-instruction Note: the instructions will only show you the process for ONE side of the machine - you can, and should, replicate that process on the other side of the machine as well to speed things up. 6. I was able to install most of the machine by myself, with the exception of when I needed to hang the pull up bar and when I wanted to install the weight stacks. The pull up bar was too heavy for my to hold overhead while trying to insert & align the bolts through the sides. The posts for the weight stacks wanted to fall on me if I let go of them for too long while grabbing the next weight. Everything else was pretty straight forward and easy to do. Only hand tighteng until you are ready to start adding the cables is critical for easy alignment of everything!! 7. There is a little bolt with a nut when you are assembling the cables that makes a big difference on the feel of how smooth the cables feel once assembled. The tighter you make this, the smoother the cables feel. HOWEVER, if you tighten them too much, you may not keep alignment with the holes lower in the weight stacks. 8. The BOTTOM cables with light weight do have lack of resistance on the eccentric movement… if I tighten the bolt (from my #7 comment above) enough after I place my pin in the weight stacks, it does help minimize this, but it’s definitely still there to a degree and does not feel as smooth as a commercial machine (on the eccentric motion specifically). I am hoping this will wear in and get smoother with time. But for now I’ll just hand adjust that bolt each time I want to use the lighter weight since it’s easy enough to hand adjust. The TOP cables are incredibly smooth and feel very comparable to commercial-like machines. Since we usually only need to use 1 cable for 2:1 ratio we tend to just use the top cable and when we want to lift heavier with 1:1 ratio that’s the only time we’ll use the bottom cables but since it’s heavier weight in 1:1 it doesn’t really have the “floating” problem. Adding on the [empty] 5lb extender weight pins to the weight stacks also helps add some weight to help gravity pull everything back down on the eccentric and helped minimize the “floating” as well. 9. The smith machine is smooth!! Definitely not a counter-balanced bar, it’s a ~45lb bar, but feels like it’s heavy duty and made well. TBH the heavier bar just saves me from needing to buy more weights 😂 so that’s a win from a home gym perspective! 10. I measured while assembling & purposely did not install all of the spring safety components for the smith bar so I can go low enough on the machine for hip thrusts. With ONLY the yellow springs at the bottom, I am able to get veryyy close to full range of motion. I could’ve opted to remove the springs and only have the black spacer nuts, or nothing at all, at the bottom to achieve maximum range of motion, but I wanted to have something there just in case the smith bar fell accidentally. We are not planning to use the safety’s higher up on the smith bar, so removing the adjustable components didn’t bother us to get added range of motion. 11. We did not choose to install the pegboard on the back of the machine since we wanted to put a mirror there (we are going to hang the peg board on a wall somewhere). MF customer support was able to confirm that this does not provide any structural integrity for the machine, just slightly more stability at most, and is ok to choose not to install. Thoughts on the machine’s performance: This machine is heavy duty and definitely an all-in-one. I don’t think we were expecting to like all of the different capabilities on it as much as we do, since a lot of “home gym machines” don’t usually feel as good as commercial machines. But major fitness really made a beast of a machine here. We’ve tried out basically every capability this machine can offer and have been happy with each of them. The only somewhat negative is the BOTTOM 2:1 cables having a slight “floating” sensation on the eccentric motion, but considering we can use the TOP 2:1 cables (which feel great) anytime we need to use a 2:1 cable, and it doesn’t “float”with the 1:1 ratio setup, this is a minimal complaint. It’s also a very sturdy machine, we have had no concerns with it being able to stand up to heavier weight. The biggest selling points for the B17 over the B52 Pro in our opinion is the increased weight capacity to the weight stack extender pins (B17 can hold 260lbs extra per stack compared to only 130lbs for the B52) and the 1:1 ratio option. These are two features you can’t currently get on the B52 but they allow substantially more weight capacity for the cables compared to the B52 and makes it so you really won’t outgrow the machine. Overall, we are very happy with our purchase! It is an investment piece, but one that makes it so you won’t have to grow out of it. It’s a very well made machine with great quality, and is beautifully designed (icing on the cake).

Bought as an upgrade from the Mikolo M4 2:1 dual system- we were stoked to get this setup. Putting it together proved tedious but not difficult. Footprint fits perfectly in the space. The smooth upgraded pulley wheels and cables is fantastic. The single hand adjustable cable guide was a game changer for my husbands arthritic hands. Having a stack to pin versus plates to load is the best choice we’ve ever made for an all in one. Downfall for me is the drop height- doesn’t go low enough for hip thrusts on the bar. You would have to remove the safety bars all together for that😔. Smooth pulleys and looks good in the gym setup. Plan to have for years to come! We modified the plate holders to a side placement to allow for a deeper set back in the room. Easy mods with the various prefilled holes in back frame.
