Dear FA Team, I just wanted to share how much I’m enjoying the Hyper Pro — it’s an absolute masterpiece! The possibilities feel endless with what I can do on this machine. The build quality is top-notch, and it’s become an essential part of every workout I do — I always include at least one or two exercises on it. I highly recommend it to everyone, from beginners to elite athletes. You've created something truly valuable, and I appreciate the passion and innovation behind it. Thank you for bringing this to life! Best regards, 😉✌️ Uldis Ūdris

This machine is simply fantastic! I wasn't sure about buying this but took advantage of a package deal by adding the leg developer & squat attachment. Very happy with the equipment. It is great quality, easy to assemble with good video-guidance, so easy to configure, and the movement of the leg developer is smooth & friction-free. The squat attachment is actually great for calf raises. I'm based in the UK yet US customer support were superb to deal with. 👏

The Leg Developer Attachment + Upper Body Kit Bundle setup has completely transformed my home gym. The leg developer feels just as smooth and challenging as commercial equipment, and the constant tension during curls and extensions is exactly what I was hoping for. Super easy to attach and adjust, and the build quality is rock solid. The upper body kit adds a ton of versatility—I've been using it for rows, curls, presses, and even tricep work. It’s amazing how much I can do now with just one machine. The whole bundle is compact but powerful—perfect for small spaces without compromising on functionality.

This really adds to the functionality of the Hyper Pro - brilliant to add so many additional exercises. Easy to set up/attach to the Hyper Pro and to adjust.

While this won't be in the same league as a dedicated leg extension or leg curl machine, it's surprisingly good for an add on. Using it with weight plates, the tension is pretty good for a unit that doesn't allow you to adjust the camber/leverages to change the resistance curve. The padding is comfy and action smooth, and it's very easy to add and remove to the Hyper Pro. As is with the Hyper Pro, the build quality is very good, I can't see any problems for long time home use. One benefit this machine has over some dedicated leg extension machines is that without a back rest, you can lay back and lengthen the quads even more for a better stretch. The bottom of the movement could use a few more inches to really max the stretch, but this can be solved by adding a pad or rolled up towel to your ankles.

Takes a while to put together but the how to video clips are probably the best I have seen so made it super super easy to assemble (my mrs did most of it in all honesty). At first it all looks rather daunting when you look at everything in regards to how it works but again the online how to use guides are amazing and got me up and running in no time. I have used this for about about 3 weeks now and absolutely love it so incorporated it into all of my workouts as i was suffering a lower back problem which was preventing me running but this literally got me back out there again so worth every penny for me. I have the Full Outlaw triathlon booked for 2026 and using this i'm now confident i will be on the start line. As an older athlete at 62yrs old i find this better than trying to lift heavy weights and really helps with flexibility too using just body weight. Initially thought it was a bit pricey but to be fair its abolutely solidly made and has so much versatility i do think its worth the outlay
