With all the digging and diving that she does in just one beach volleyball match, it's no wonder that Olympian Kerri Walsh has a truly superior posterior. Every ball-saving dig she makes in the sand engages all the muscles in her leg, but particularly her butt.
To reveal a better backside like Kerri's, add these two workouts to your fitness regime.
Alternate between workout A and B for three workouts each week. (So, during week one you’ll do A-B-A, then start with workout B during week 2). Complete 10 reps of each move, moving from one to the next with little to no rest. Rest one minute, then repeat up to two more times. (More: Shape-Up Shortcuts That Work)

Press your left heel into the step and push your body up until your left leg is straight and you’re standing on one leg on the bench, keeping your right foot elevated. Lower your body back down until your right foot touches the floor. That’s one rep.

Lie faceup on the floor with your lower legs and heels on a Swiss ball. Push your hips up so that your body forms a straight line from your shoulders to your knees.
