"Rebounding (mini-trampoline) builds muscle, strengthens joints, and improves metabolism. Rebounding stimulates the neuro-muscular system that can be achieved with no other exercise. Rebounding combines gravity, acceleration and deceleration. It is like no other exercise. Because of the alternating weightlessness and increased gravitational pull (G-force), EVERY single cell, organ, and muscle is exercised."
