1. V-Pass With Exercise Ball
Begin by lying face up on the floor, holding an exercise ball over your head with both hands, your legs together and extended straight on the floor.
1) In one movement, tighten your core and lift your arms and legs off the ground, placing the ball between your feet.
2) Squeeze the ball with your legs and lower your arms and legs back to the floor.
3) Repeat, passing the ball back to your hands. That's one rep. Start by doing 8 to 10 reps and then increase as you become stronger.
