Temple of Gainz Leg Extension & Leg Curl Combo Machine – Pros, Cons & Verdict

If you are setting up a private training studio or building out your home gym and want to save space while still getting two legit lower body isolation movements, this combo machine is worth a look.

Why I Bought It

I wanted two specific movements in one piece of equipment. A seated leg extension and a prone leg curl. I had the Titan plate loaded combo before this and it worked, but it was a pain to drag plates over and the resistance curve was not great. I wanted something selectorized so I could change weights fast between clients and get a smoother strength curve. This machine hit that sweet spot. It is not as expensive as the big commercial brands, but it is not a budget Amazon special either. It sits in the middle and that is why I bought it.

Build Quality

The build quality is solid. The welds look clean. The frame feels sturdy. The pads are firm but not painful and they do not pull hair off your legs like some cheaper leg machines. All the pins use nice aluminum handles and every adjustment point is laser etched so you know exactly what setting you are on. The weight stack goes up to 264 pounds and it feels close to a 1 to 1 ratio. For most people that is plenty and if you need more you can always add a gym pin or adder weights on top. The footprint is around 4.2 feet long and about 3.2 feet wide and just over 5 feet tall. So it is compact for a two in one machine but you do need a little room in front for leg extensions and a little room behind for the curl setup. Cables feel smooth, no sticking plates, and the selector pin is tethered so you do not lose it.

Ease of Use

Switching from leg extension to hamstring curl is fast. Bring the pad up, adjust the roller, drop the back pad and you are on the curl. Bring it back up and you are on extensions again. All the adjustments pop in easily with one hand. That is a big upgrade from the plate loaded stuff where you have to unload it, flip the arm, reload it, and waste a minute every time. Because this is a combo machine the seat and back positions are fixed. So for shorter clients I sometimes throw an abmat behind them to bring them forward. Taller people up to around 6 foot 5 fit fine. That is just part of the tradeoff with a combo unit.

Performance and Range of Motion

This is the part most people care about. How does it actually feel.
On the leg extension you can get a really good stretch at the bottom. I was worried it would not flex enough at the knee but it does. The one thing I do not love is the crossbar at the bottom. If you set the roller to the deepest position it can be a little awkward to get your foot in behind the roller. It is not a deal breaker, it just takes a certain way of stepping in. Once you are in, the motion is very smooth and the tension is consistent from bottom to top. I would give the leg extension a 9 out of 10.
On the lying leg curl this machine is excellent. You can set the roller so there is tension right away in the stretch position. The plates stay off the stack so you get constant tension. The resistance is smooth all the way through and everyone I have put on it fits the machine and can reach the handles. If someone has tight hamstrings I just move the roller up one notch and it is comfortable. I would give the lying leg curl a 10 out of 10.

Pros

✅ Smooth selectorized resistance
✅ Two legit movements in one compact footprint
✅ Great build quality and comfortable pads
✅ Fast to switch between extension and curl
✅ Works for a wide range of heights and clients
✅ Resistance profile feels consistent on both movements
✅ Weight stack is heavy enough for most lifters and can be loaded more

Cons

❌ Crossbar makes it a little awkward to get into the deepest leg extension position
❌ Fixed seat and back angle means very short lifters may need a pad behind them
❌ Costs more than plate loaded options

Final Verdict

The Temple of Gains leg extension and prone leg curl combo is a very good option for small gyms, private training studios, and serious home gyms that want both movements without buying two separate machines. It feels smooth, it is built well, it fits most people, and it is fast to adjust which matters a lot if you train multiple people. The only real annoyance is the crossbar when you want max knee flexion on extensions, but even with that I still use it in that setting because the stretch and tension are worth it. I would buy it again and I recommend it.
