This is a great ball exercise for the abs and inner thigh.
Lying on the floor, have your legs extended straight up with the ball between your feet. Arms should be straight out to the sides, head resting on the floor.
Exhale and twist the ball to the left using your ankles and calves to hold the ball steady. Hold for two seconds, and twist back to center.
Repeat the same twisting motion with the right side to complete one rep.
