This weeks leg routine...

[hellboy]

I can say that in my experience heavy leg presses cause FAR more aggravation of my low back injury than heavy squats.

With squats you can control your form. I have yet to find a leg press machine that allows me to maintain the correct arch in my lower back. Hammer Strength, Body Masters, and Cybex are the ones at my gym.

That may not be an issue for you if you have a healthy low back or if your warm ups aren't really heavy. I just assumed they were cause of the low reps.

I know some of my old PLing buddies got some nasty hip strains and knee aches doing low rep leg presses. I wouldn't mess with them. If you want to really want to hit your quads try doing the leg presses slower, like 4 down, pause, 4 up, don't lock out, do 5-6 reps like that.

Leg injuries suck.
