Ball V-up

Lie on your back, legs straight and arms fully extended above your head with an exercise ball positioned between your hands. Tighten your abdominal muscles, lifting both the ball and your heels off the floor.

Raise both your hands and feet together, bringing the ball to meet your legs. Pause, then lower back to the starting position.

Perform 3 sets of 15 reps.
