Keep your weight in your heels to ensure you get the best tush-shaping results.

Step 1: Hold a dumbbell at the base with both hands and stand straight up.

Step 2: Move your legs so that they are wider than shoulder-width apart. Your knees should be slightly bent and your toes should be facing out. This is the starting position. (Note: Your arms should be stationary while performing the exercise.)

Step 3: Slowly bend your knees and lower your legs until your thighs are parallel to the floor.

Step 4: Press mainly with the heel of the foot to bring the body back to the starting position while exhaling.

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.
