10. Medicine ball pull over

Hold a medicine ball straight up in the air. Slowly lower the medicine ball behind your head as far as you can, keeping arms lengthened with a soft elbow bend. Squeeze your chest and triceps as you bring the ball back to the original position above your chest.

Why it works

This exercise is a great way to wrap up a chest workout or to do on its own. The muscles are working hard but without the resistance of a weight.
