Try these exercises at home or the gym with just your body weight. Aim to complete one to two sets of about 15 repetitions per side. Once you can easily do up to 15 reps, step up your workouts and sculpt butt muscles even more by holding dumbbells or a weighted bar for added resistance.
Do the routine three times a week on nonconsecutive days. With a five minute warm-up and five minute post-workout stretch, the entire routine takes under 20 minutes (or less if you do just one set).
