The stability ball hand walk is a challenging exercise. While the chest is the main target, you almost get a full upper body workout doing it. Even the abs are heavily involved in this exercise. It looks easy to perform, but don't be fooled. The stability ball hand walk requires "above average" strength levels, balance, and coordination in the upper body.

Start with your stomach and upper thigh areas resting on the ball. Place your hands on the ground to support the upper body (as in the push-up position). Walk your body forward with your hands until the ball is on the shins or shoes. Return to the starting position and repeat several times. Be sure to keep your rear down and back flat as you perform this exercise. You will definitely feel this one working.

Note: This exercise is contraindicated if you have any wrist issues. Also, you can make this exercise easier by walking forward until the ball reaches the knees.
