I’ve personally used the Crossover Symmetry system to improve my shoulder health and performance and gain a surprising amount of muscle mass in the process.
It’s designed to strengthen the often neglected and weaker postural muscles of your scapula and rotator cuff and prepare your body for overhead work.
They also recommend crossing the cords to maximize the angle of resistance and range of motion. And it provides multiple levels of customized resistance and many portable and accessible attachment options for power racks, doors, fences, etc.
