Single-Leg Bridge Kicks Love this backside move that works the hamstrings, too. Lie on your back, and place your hands on the floor for stability as you bend one leg and lift the other leg off the ground. Pressing your heel into the floor, lift your pelvis up, keeping your body in a stiff bridge position. Slowly lower your body to the floor. Repeat three sets of 15 reps on each side.
