Squats and deadlifts hands down. I doubt anyone is going to answer incline press, unless they've been doing bodyweight-only squats, or deads with 2.5 lb. dumbbells!
To be honest I really like Hack squats. I used to squat but you can't go all out like you can on a hack squat machine. Just my opinion but my legs are sore as hell today.
squats, when incorporating squats into a workout, they should always be the first. why, because the amount of growth hormone secreted is huge, this infact will make the rest of your workout more worthwhile.
