One Leg Hamstring Dips on Stability Ball
Work your balance while toning your lower body with this advanced move.
Begin on your back, with arms at your sides, hips and buttocks raised off the floor and your feet resting on the exercise ball. Bend one knee so that a single leg is resting on the ball.
Lift your hips even higher while keeping your leg in the air. Return to start.
Repeat for the desired number of reps. Switch sides.
