Balance Push-Up:

Lie facedown on an inflated exercise ball with both hands on
the floor. Walk your hands out, allowing the ball to roll beneath your body
until it is under your shins. (Beginners can keep ball under thighs.) Your
hands should be directly below your shoulders. Now do a push up keeping the legs straight while only bending the elbows to 90 degrees.

Hand-to-Foot Ball Pass:

Lie on your back, with your legs extended on floor. Hold the
ball with both hands, and extend arms back over your head. Raise arms and legs
toward each other, lifting your head and shoulders as you do.

Knee Tuck: Step 1

Lie facedown on the ball with both hands on the floor. Walk
your hands out, allowing the ball to roll beneath your body until it is under
your shins. Your hands should be directly below your shoulders. Tighten your abs and bend your knees, drawing them forward,
so you bring your legs and the ball under your torso. Hold for a second.
Straighten your legs and uncoil as you press back to the starting position.
