Sumo lunges are great for all-over shaping, as well as blasting annoying, stubborn fat on your hips.

Step 1: Unlike the forward lunge, the sumo lunge begins with your feet shoulder-width apart, subtly mirroring the stance of the famous Japanese wrestlers.

Step 2: With your hands on your sides and your core engaged, perform a roundhouse-style kicking motion by lifting the knee of one leg, bringing the leg forward and out, then returning it to the starting position. Without losing momentum, kick the same leg out sideways, leaning your body in the opposite direction of the kick.

Step 3: Return the foot and transition into a squat.

Step 4: As you rise from the squat, explode into a short jump, lifting your heels about two inches off the ground.

Step 5: Repeat with the opposite leg.

This stability ball exercise really engages your butt for a belfie-ready rear end.

Step 1: Lie on the floor with your lower legs on an exercise ball. Extend your arms out to your sides.

Step 2: Straighten your lower back, knees and hips, raising your back and hips off of the floor.

Step 3: Keeping your hips and lower back straight, lower your knees, pulling your heels toward your rear end. (Allow your feet to roll up onto ball.)

Step 4: Lower to your starting position by straightening your knees.
