Do squats every leg day, first exercise. In fact, I mostly do squats for legs. They work out so much of your legs. Plus help with your core and balance. Don't have to squat no huge amount, just what you're comfortable with. Your legs should be your strongest muscle cuz they the foundation. My belief is if you can bench more than you can squat, then you ain't working out correctly. I have been slacking on the deadlift tho. Should start back up maybe on Friday cuz tomorrow is legs.
