Hamstring curl with bridge on ball
Tone up your lower half and give your booty a boost with this hamstring curl with a bridge performed on a stability ball. Lie on the ground with your feet on the ball. Place your hands on the floor for balance. Lift your hips off the ground, and then use your hamstrings to draw the ball in toward your body. When your knees are pointing toward the ceiling, lift your hips until you form a straight line from knee to shoulder. Reverse the exercise and return to start. Repeat 10 to 15 times.
