I'm only 106 lbs (also 5'2" and a chick) so I don't claim the tiniest fraction of these guys' expertise.
But, here' s my problem with squats as opposed to leg press:
1. The knee factor. You gotta treat the knees as priceless diamonds, because when they go, THEY GO! Ouch! No training for a long time!
Leg presses feel better on knees--especiall ATF, which seems almost dangerous to me.
2. Squats seem to involve more cardio. Maybe because the whole body is moving. (???) Anyway, that means my heart get "fatigued" almost before legs do. Leg presses are strictly quad and glutes. Otherwise you're lying down. Barely cardio at all.
What do you think?
