With each bounce, you go from experiencing weightlessness to as much as three times normal g-force (gravitational load). Your muscles respond to this by alternately flexing and relaxing, strengthening and toning them naturally and efficiently. And since all 638 of your muscles are in on the action, no corner of your body is left out on the healthy, revitalizing effects.

When you bounce, three forces come into play that strengthens and cleanse your cells at the same time: gravity, acceleration, and deceleration. Unlike other forms of exercise, you are vertically accelerating and decelerating on the same plane as gravity. These three forces combine to squeeze out toxins from the cells at the bottom of the bounce. At the top of the bounce, pressure is decreased and your lymph can flow upwards. Circulation is enhanced and the lymphatic system is pumped and cleaned.

Bone density is also improved because of the gravitational effects of rebounding on the skeletal system. It is the form of exercise NASA uses for its astronauts to recover from prolonged weightlessness and therefore weaker bones.

Rebounding encourages muscle performance in circulating fluids to lighten the heart’s load making it the ideal cardio workout. Studies have found rebounding is 68% more effective than running as an aerobic exercise.
