Using a rebounder (mini-trampoline) is one of the most efficient and effective exercises that one can do. Not only does the rebounder help in overall health, weight loss, balance and strengthening the immune system, it is also very easy and fun to use and can be used by people of all ages and health conditions.
Doing just four different types of bounces on a rebounder is fine for most people. First of all, there is the "health bounce," in which you bounce gently, with your feet hardly leaving the mat. This circulates your lymph very efficiently. Then there is jogging, which is the same as if you were jogging outside somewhere. This both circulates your lymph and causes your muscles to work some. The third exercise is sprinting in place. A rebounder is excellent for sprinting, because 85% of the impact you'd experience on hard ground is absorbed by the rebounder! Of course, sprinting is great for all your muscles, as well as for your breathing and your stamina. Finally, there is the strength bounce, which consists of bouncing up off the mat as high as you can. Doing that causes your body to temporarily weigh 3.5 G's when you come down, and to be weightless when you go up. This action causes every cell in your body to become stronger.
Sprinting, or doing other very vigorous exercise on a rebounder, causes another very interesting and highly valuable phenomenon. Just one minute of such exercise can increase your neutrophil (killer cell) count by anywhere from 2 to 7 times normal! (Based on Dr. Arthur C. Guyton's "Textbook of Medical Physiology," The exact increase in neutrophils depends on which edition you read.) The temporary increase of these killer cells enables the lymphatic system to better attack cancer cells, bacteria, fungi and other foreign or waste materials in your body.
