I would love to see a beefier version of this just to simply mitigate some of the flex in its use, mostly during hamstring curls, but overall this thing excels for its cost. Excellent strength curve and value. Would absolutely buy it again.

For the price this is a great piece for legs. The only issue is the flexion on the pad when doing heavy weights.

For the money it’s worth it. You’ll get solid work in for what needs to get accomplished. Bit of a tipping issue during leg extensions but the leg curl is perfect in terms of feeling the weight throughout the entire motion

I picked this up for ~$350 on sale and I think it’s pretty solid for the price. I wish they would add a 360 degree sun dial to add more ROM choices but the 4.0 seems like a solid contender for its price. My foot catch arrived mostly square, time will tell if it remains that way as the machine does eat plates.

I have an impossible time geting all the pieces to line up straight on it but it doesnt seem to affect the performance any. I love the way this piece feels and has added a lot of variability to my programming.

It’s a sub $400 leg extension/leg curl with a great resistance curve. Is it perfect, no. But it does what it says and does it well. Would add to my gym again no question

It’s a leg extension and leg curl and it is affordable, mine had some fit and finish issues but overall I’m happy with it. I don’t think it’s a forever piece to my gym, but I was in the market for a lower body machine and it’s doing the job. I’ll probably replace it with a different leg machine, not a leg extension.

It’s a $400 leg extension/leg curl. Outstanding value. Ergonomics and resistance curve are awesome. Can get a big stretch in both modes, though the crossbar gets in the way at the bottom of the leg extension. The seat is a little wiggly and the pop pin isn’t great, but once you lock in with your arms, there’s no movement during the exercise. The foot pad seems a bit wimpy and could deviate from being square over time, but not so far for me.
