PowerBlock Supine Fly Unilateral
The PowerBlock Supine Fly Unilateral performed on the ball is an advanced exercise requiring a strong core. By weighting the body on one side it forces you to work harder to stabilize the movement. The surface of the ball provides for more range of motion and therefore recruits more muscle to perform the action. If one side of you chest is stronger than the other this exercise can help even out development. Bodybuilders like to use this exercise as a “finishing” movement on their chest day.
