Leg extension machine vs rest

Post by excore » Thu Apr 03, 2014 8:13 pm

In hack/barbell front squat/leg press you basically assist your thights with your glutes. Problem is pritty much none of it is good glute excercise as you go long long time failure on quads. Movement itself is not good for glutes. People say squat is #1 excercise for glutes but that's totally rubbish. Doing lunges with wider feet range or any sort of hip extension is by far superior.

But my question is 100% quads releated. What makes any other glute assisted knee extension movement superior to leg extension machine?

What is wrong with leg extension machine? Seems like everyone seems to avoid it saying it's bad for building strenght and muscle.

Is it only because it's isolation? I mean that must be only reason because it's still same old knee extension movement.

The quads can move dramatically more weight in something like a squat than they can in a leg extension. Granted other muscle groups are involved, but they don't assist the quads in actually straightening the knee.

Many people find leg extensions uncomfortable or even painful.

Leg extensions aren't very functional. They don't develop balance or motor skills, build core strength, etc.

Leg extensions don't produce the kind of hormonal response you get from major compound lifts.

The shear forces on the knee is what makes it dangerous

I was never a fan of the leg extension machine. It never felt right on my knees and after 15+ years dancing they're not in the best shape in the first place anyway.

@KittenJ:

Don't take anything excore posts seriously. Nobody else on this board does.

I'm beginning to see that. Sometimes it's fun to feed the trolls.
