squats
deadlifts (variations)
lunges or split squats
reverse hyperextensions (if at home can use a stability ball, though its not too tough)
leg curls (on stability ball for hammies, if at home)
Agree... squats have made my ass great (from what I'm told ). Seriously, I've noticed such a big difference in my ass and thighs!!! I also do lunges with DBs.
Love squats! I really feel like I've worked after a squat workout.
