Just jumping 30 times a day will make your bones stronger and improve your health and fitness. But don’t do it cold. Warm up until you break a light sweat. You just have to jump up and down, not off of anything. It's the impact that stimulates your bones. You need two things: a soft surface to land on and your doctor’s ok.
