Need some help here. I keep seeing the big guys using this exercise and they go real heavy, most seem to use it first to pre-exhaust but Ive read and heard that its real bad for the knees and I have one bad knee.

I think leg extensions help strengthen the knees, one of my physical therapists had me doing them one leg at a time with low weight and high reps of course.

I'm a firm believer in leg extensions. no need to go crazy heavy. This exercise is more about blood volume anyway. Of course use a decent amount of weight, but focus more on the movement and squezing through the whole exercise.

If I do them, it's dead last. I've seen the guys that started with them and went superheavy 10 years later.... It isn't pretty. I do them as my last exercise in the FST-7 system. Talk about blood volume. I walk out of there looking like I'm riding an imaginary horse.

Leg Ext. are nothing more than a leg exercise, they work just like any other leg exercise. You get out of them what you put in them.

If you keep in mind that you don't want your ankle joint coming past your knee when you come down, it'll save your knees. It's all about keeping your ankle joint in front of the knee joint. Anytime you have your knees over your toes, you're just asking for trouble

That's the truth. When lowering the stack don't go past 75 degrees and return back up in a smooth fashion as to not travel above horizontal which will also hyperextend the knee.

Yea, don't lock your knees out completely, you can still get a good squeeze without locking them out. I don't know if you've ever heard of them or used them, but try looking into Tommy Kono Knee Bands, they will make a difference for you

Most of the time on a leg extention stack weight machine the starting point is past the 90 degree point so to stop this I grab a extra stack weight and set below the weight im lifting so when sets done the knees not hyperstretched.Basically the pinned weight is sitting on top of say the extra 5lb weight placed on stack after it's raised..

I just go by feel, but I'm pretty good about knowing when I'm close to the 90 degree angle on my knees
