The Major Fitness Flex Arms are built to expand what your cable system can do—and paired with the right cable machine attachments, you get even greater control over training angles, resistance paths, and movement freedom.
Featuring multi-directional adjustability, the Flex Arms offer five horizontal positions and four vertical positions, allowing you to fine-tune cable pull points to match your body mechanics and exercise goals. Whether you're training chest, shoulders (e.g., cable lateral raises), back, or arms, the ability to reposition the cable path helps create smoother, more natural movement patterns. See it in action with our Cable Chest Fly guide.
Included Freedom Connector expands functionality further—linking both Flex Arms for dual-arm movements such as lat pulldowns, seated cable rows, and triceps pushdowns, or mounting to a single arm to create an adjustable anchor point for varied grip widths and targeted cable exercises.
Integrated aluminum pulleys provide quiet, durable operation, while bearing-supported rollers allow the arms to glide smoothly up and down the upright. Bearings are also built into the pivoting adjustment points, ensuring effortless rotation and precise positioning at every angle.
The Flex Arms are built exclusively for the Major Fitness B52 PRO and F22 PRO. They mount directly to the uprights of each machine and connect seamlessly to the cable system, giving you fully adjustable cable positions across multiple horizontal and vertical settings.
Pairs only — and that's intentional. The system is designed with one arm per upright, so you get the full range of what Flex Arms can do: symmetrical movements like lat pulldowns, seated cable rows, and triceps pushdowns, plus independent single-arm work on either side whenever you need it.
Each Flex Arm attaches to your machine's upright on bearing-supported rollers that slide smoothly up and down. Pivot the arm to dial in your preferred cable angle, and the built-in aluminum pulley keeps the cable running cleanly through every position. It's straightforward to adjust and locks right where you need it.
You stop working around your equipment and start training the way your body actually moves. With five horizontal and four vertical positions, you can match resistance to your natural movement path — not the other way around. That means cleaner reps, better muscle engagement, and more exercise variety overall. The included Freedom Connector ties it all together, supporting both dual-arm and single-arm cable setups from a single attachment.
A lot of your cable staples, and then some. Chest flys, cable lateral raises, lat pulldowns, seated cable rows, triceps pushdowns, bicep curls — the Flex Arms handle all of it. Run both arms together for bilateral movements, or isolate one side for targeted unilateral training.
Overall rating: 4.8 / 5 from 5 reviews.
The Flex Arms have been one of my favorite upgrades to my home gym. The movement is incredibly smooth, and they add so much versatility to my workouts. The build quality is outstanding—they feel solid, durable, and operate flawlessly. Whether I’m training chest, back, shoulders, even legs, they provide a natural range of motion and a great muscle contraction every time.
If you have the B-52 Pro or F-22 Pro, I’d honestly say the Flex Arms attachment is a must-have. Buy them now! It adds so much versatility to the cable system. The extra height makes lat pulldowns feel much more natural, the increased range of motion is perfect for cable flies and other movements, and the whole setup feels even more solid. I already had the upgraded pulley system on my Pro, but adding the Flex Arms completely changed how I use the rack. One of my favorite upgrades.
These articulating flex arms are really solid and feel very well built. I like that they effectively replace the lat pulldown extenders, which honestly were a miss for me due to the cable length. The flex arms feel far more useful and functional, so in that sense they’re definitely an upgrade. My main issue is that they clash with the pull-up handles on the rack. Because of that interference, it prevents doing a true unilateral lat pulldown, which was something I was really excited about when I bought them. They can clash a little with the band horns as well, but I don't foresee needing them in that position for any exercise. It’s also becoming clear to me that this rack and its accessories just aren’t really designed with tall people in mind. If there were a replacement pull-up cross-member where the handles didn’t get in the way—ideally something cambered to give taller lifters more clearance—this would easily be a five-star product for me. Also, something to note: Mine came with some pretty significant scratches out of the box. No effect on functionality so I'm not too butthurt about it, but not ideal for a brand-new product.
I absolutely love these arms. They have leveled up my B52 PRO. They add so much functionality. Buy them you will love them!
These are amazing! Best upgrade I've done. So much more useful than the standard pulleys. So many ways to adjust them means way more variety.
