Stretching makes the muscles supple. It increases muscle fiber density and it helps create greater balance in the way muscle tissue is distributed along the muscle length. As a result, stretching helps increase muscle power and increase the degree of freedom of movement a muscle group enjoys. As a total, stretching liberates the body from its own strength and places it more under your control. Superhero Stretch is a workout that delivers on all these fronts.
