  Firm backside jiggle with plyometrics.

Jumping uses all of your large lower-body muscles, which raises your metabolism with firming your butt and hips.

Twice a week, do 3 sets of 10 jump squats:

Stand with feet shoulder-width apart, arms bent and hands clasped in front of your chest. Lower into a squat until thighs are parallel to the floor. Jump up, pushing off the balls of your feet. Land with soft knees, lower into a squat again, and repeat.
