This move works your keister and your inner thighs.

Step 1: Begin by standing with your feet shoulder-width apart and your hands on your hips.

Step 2: Step out to the right and shift your body weight over your right leg, squatting to a 90-degree angle at the right knee. Try to sit down with your butt, keeping your back as upright as possible.

Step 3: Push off and bring your right leg back to center to complete one rep.

Step 4: Complete 15-20 reps on your right side, and repeat on left side to complete one set.

In addition to toning up your lower backside, this move also works your inner thighs.

Step 1: Start standing with your feet slightly wider than hip-width apart, and your toes turned out to 45 degrees.

Step 2: Lift your heels off the floor, balancing on the balls of your feet, and bend your knees.

Step 3: Lower your body straight down, keeping your hips under your shoulders and your back straight. Make sure your knees open over, but not past, your toes as they bend.

Step 4: Slowly straighten back up and then lower your heels.

This movement is great for giving your buns some extra lift.

Step 1: Stand on your left foot, holding dumbbells, a body bar or medicine ball. Lift your right foot behind you and bend your knee so your right lower leg is parallel to the floor.

Step 2: Bend forward at your hips, and slowly lower your body as far as you can. Pause, then push your body back to the starting position.

As you come up, think about using your glutes to push your hips forward instead of lifting from your back. Keep your core engaged and chest up during the entire movement.

Keep your core engaged and remember to feel the burn in your butt -- that's how you know you're doing the move correctly.

Step 1: Lie flat on your back, gripping your stability ball on both sides.

Step 2: Reach your arms and your legs straight up simultaneously. Keep your back flat on the floor. Pass the ball from your hands to your legs.

Step 3: Lower your legs and arms simultaneously.

Step 4: Now reverse it.

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.
