im just gonna add one bit of advice here

if you do squats and leg presses on the same day ALWAYS do squats first; if your legs are fatigued from leg press when you get on the squat rack, there is much more chance of losing stability and straining a muscle trying to regain control/balance. when you lift you should always work from compound exercises down to smaller exercises, and although you put more weight on the leg press, you are using your whole body for squats and you dont want your prime movers to be fatigued from the leg press when you step up to the squat rack
