Straight to the point, this boost packs a big punch. We use creative coordinated movements and eccentric exercises to strengthen the muscles of the shoulder cuff and shoulder blades while hitting up some core as well. Strength doesn't develop overnight and oftentimes it's our inability to keep the arms steady as a foundation when we are playing with balancing. This boost will make you strong in just the right areas so you can hold yourself up in svelte manner. Shrugging not allowed!
