Medicine-Ball Weight-Plate Thoracic Opener

Position a medicine ball on the floor near a wall and lie back so your upper back rests comfortably on top of the ball with your feet planted flat against the wall.

Hold a weight plate securely with both hands directly above your chest with your arms nearly straight.

Inhale deeply as you slowly lower the weight plate overhead toward the floor, allowing your upper back to arch gently over the medicine ball.

Exhale as you engage your core and press the weight plate back up to the starting position above your chest.
