FAQs
Is this machine suitable for users of all heights?
It accommodates athletes from 4'9" to over 6' tall.
Does the machine make noise during operation?
It's very smooth and quiet, but it needs lubricant after a while.
Can I use Olympic-sized (2") weight plates?
The machine is designed for 1" & 2" plates standard plates. Max load is 150 lbs.
My home gym has very limited space. Is this 2-in-1 machine really better than buying two separate units?
Absolutely. The biggest pain point this machine solves is space efficiency. It integrates both Leg Extensions (Quads) and Seated Curls (Hamstrings) into a compact footprint of approximately 10.5 square feet (39.5" x 34.6").
Is the assembly process a nightmare? I don't have professional tools.
Most of our users find the assembly quite straightforward. Based on feedback, it typically takes between 15 to 45 minutes. The machine comes with a detailed manual, and many of the core components (like the bearings) come pre-assembled.
It works pretty well the only downside I see is the weight stack is very small so you can’t fit much weight on it. For the price you can’t really beat it.
It’s honestly very nice, I enjoy it and it was a great add on to my home gym. Downside is you can’t add more weight if you have larger plates. Also you need to start with the weight loading bar out front instead of straight down for resistance throughout
Equipment was packaged very well for shipping. Pay attention to the instructions and the directions pieces are facing. Overall after assembly machine seems sturdy. Time will tell.
10/10 for my use. People are complaining about the instructions are not clear. The instructions are pretty clear. You just gotta take it one step at a time. The one thing I will note is that there’s a little bearing “z” has to be put on. I did forget this and it felt off. Put the bearing on its good. In order for you to do hip thrusters or ab workout you were gonna have to remove the top foam piece, which that’s only a 17mm bolt.
I’d still rather a quick disconnect for that but it’s not bad. I mainly got this for leg curls and leg extensions. So far I really enjoy this piece of equipment. I’ll update after a month or if something breaks. June 19th.
You get what you pay for with this machine. This machine will allow you to get a decent leg workout out, however the resistance does not allow the movement to go all the way through as a heavy duty gym. I felt like my legs got the pump they needed but did not feel my legs where able to get full range of motion.
I don’t think any one has read these instructions prior to shipping. Good thing I can visually build just about anything. For example 44 washer on the instructions does not provide the information for it. It is mislabeled as it seems. Same goes for just about every piece of hardware. Beware.
perfect for targeting your lower body. It’s well-built, adjustable, and easy to use.
It was awesome 👌
Great addition to the home gym, only one draw back...
I'm buying new clothes because my legs are HUGE!!
