Work your chest, back, and core with this teak on the classic push-up.

Kneel in front of a stability ball, and place your hands near the top. Contract your abs to keep your body still, and perform 12 push-ups by bending your elbows and lowering your torso toward the ball. Move slowly and use your core strength to keep the ball from rolling away as you complete the move. Do not allow your body to wobble from side to side. Perform 3 sets.
