Reverse curl plank on ball

Kneel in front of a stability ball, draping your abs and hips over the ball. Place your hands on the ground in front of you, and walk them out until the ball rolls beneath your shins; contract your lower abs and lift your hips slightly, then slowly lower them down. Do 3 sets of 10–12 reps.
