okay, today I did squats by themselves, and they felt alright. a few weeks ago I didn't incorperate squats into a routine and only did leg press. I know squats has quite a bit of core work in it, but I just feel I am getting a better workout for my legs with the leg press then I do with squats. I do core work by itself so that really isn't a factor in my decision. my question is does one work legs better than the other?
