How Rebound Exercise Accomplishes Its Benefits
by Morton Walker
Sometimes, for people who feel unsteady on their feet or for the elderly, handicapped, and disabled, a stabilizing bar may be added to the rebounder’s frame (see Photograph 2). It’s attached to two of the frame’s legs so that the individual needing more security can hold onto this bar and still bounce aerobically. In jumping on a well-made rebounder, the exerciser usually feels invigorated and filled with a sense of well-being. People who rebound find they’re able to work longer, sleep better, and feel less tense and nervous. The effect is not just psychological, because the action of bouncing up and down against gravity, without trauma to the musculoskeletal system, is one of the most beneficial aerobic exercises ever developed.
Rebounding aerobics is working with gravity to cleanse your tissue cells and act as an oxygenator, which, in turn, lightens the load on the heart. Also it’s fun to bounce! Much more than fun, however, rebounding provides a number of physiological pick-me-ups for the person who sustains this activity for at least ten minutes, four times a day, or for a single daily session for 40 minutes. As you bounce, your feet hit the mat with twice the force of gravity. Then just as the astronauts experience while floating in space, your body is in a state of weightlessness at the top of the bounce.
Jumping on the mini-trampoline is remarkably un-strenuous on the Joints. There’s no solid ground to suddenly stop the bouncing of your feet. Your movements are perfectly safe, and they make the effect of gravity beneficial. By working against constant gravitational pressure while bouncing, you resist the Earth’s pull. Your resistance is subtle, but it builds cellular strength. Rebounding’s alternating weightlessness and double gravity produce a pumping action which pulls out waste products from the cells and forces into them, oxygen and nutrition from the bloodstream.
Jumping’s Oxygenating Effect
If you have a resting heart rate of less than 60 beats a minute, don’t smoke, don’t have chest pain, live a healthful lifestyle, and engage in rebounding for 40 minutes or more each day, at least five days a week, theoretically it’s not likely that you’ll ever develop a heart problem if you have none now. Jumping on a rebounder helps you to attain your heart rate target zone every day that you rebound for the recommended 40 minutes.
Rebound exercise strengthens your heart in two ways: It improves the tone and quality of the muscle itself, and it increases the coordination of the fibers as they wring blood out of the heart during each beat. The aerobic effect while you are rebound-jumping equals and often surpasses that of running.
Your rate of rebounding will vary, depending on how vigorously you bounce and how high you lift your feet off the mat. Rebound exercise offers the ideal aerobic effect with almost any rate of performance, because it fills all the requisites of an oxygenating exercise.
The Detoxification Effect of Rebounding
The lymphatic system is the metabolic garbage can of the body. It rids you of toxins such as dead cells, nitrogenous wastes, fat, infectious viruses, heavy metals, and other assorted junk cast off by the cells. The movement performed in rebounding provides the stimulus for a free-flowing system that drains away these potential poisons.
Unlike the arterial system, the lymphatic system does not have its own pump. It has no heart muscle to move the fluid around through its lymph vessels. There are just three ways to activate the flow of lymph away from the tissues it serves and back into the main pulmonary circulation. Lymphatic flow requires muscular contraction from exercise and movement, gravitational pressure, and internal massage to the valves of lymph ducts.
Rebounding supplies all three methods of removing waste products from the cells and from the body. Then arterial blood enters the capillaries in order to furnish the cells with fresh tissue fluid containing food and oxygen. The bouncing motion effectively moves and recycles the lymph and the entire blood supply through the circulatory system many times during the course of the rebounding session.
Rebounding is a lymphatic exercise. As stated earlier, it has the same effect on your body as jumping rope, but without any jarring effect to the ankles, knees, and lower back that comes from hitting the ground. Better than rope jumping, however, the lymphatic channels get put under hydraulic pressure to move fluids containing waste products of metabolism around and out of the body through the left subclavian vein.
Rebounding’s Stabilizing Effect on the Nervous System
Bouncing on a rebounder is an excellent method of reducing stress. It can put the bouncing person into a trance like state and totally relax him or her. Jumping for health and fitness not only stabilizes the nervous system during the exercise period, but continues to help maintain equilibrium after one steps off the device. The result is increased resistance to environmental, physical, emotional, and mental stress. It may possibly help an individual to avoid psychosomatic disease and mental or behavioral instability.
Rebounding may be enjoyed for a lifetime and adjusted to your own particular level of fitness. It is safe, convenient and inexpensive, and its protective effects against degenerative diseases make it one of the most effective forms of motion in the work place, in recreational pursuits, or in simply exercising for the care of your body and mind.
The Physical Muscular Effect of Rebounding
An advocate of rebounding for athletic conditioning, Dr. White uses the rebounder in his rehabilitation program at UCSD. “When you jump, jog, and twist on this (jumping) device you can exercise for hours without getting tired. It’s great practice for skiing, it improves your tennis stroke, and it’s a good way to burn off calories and lose weight,” said Dr. White. “My students tell me it’s so much fun that they often exercise on the rebounders for their own enjoyment.”
Dr. White added that jumping for health is more effective for fitness and weight loss than cycling, running or jogging (see Table B), and it has the added advantage of producing fewer injuries.
The gentle bounce of rebounding is effective in returning natural, regular bowel movements to chronically constipated persons. The steady bounce sets up a pulsating rhythm transmitted by the nervous system to the brain area responsible for regulating the intestinal system, which reestablishes one’s rhythmical bowel activity. Digestion is improved as well.

The New Cleat
The Old “Bullhorn” Cleat
Competitor’s Square Corner Cleat
One of the features of our old cleat design is that if a cleat would wear out, it could easily be changed by the user. This feature continues with our new cleat design. You will note that the competitor’s design with the sharp corners is sewn onto the mat and is impossible to change requiring a new mat when the aluminum or soft pot metal wears through.

“My rebounder was delivered to my office last Friday, and I took only a few minutes before going home that day to try it out. What a fabulous feeling from the increased oxygen in just a couple of minutes! I know of no other exercise that would give noticeable energizing in 2 mins. or less. Thank you to Tropical Traditions for adding this wonderful item to your list of health-raising habits!! I want to tell everyone I love about it (as I did about coconut oil), but I’ve decided to begin by making such excellent changes in myself that they won’t be able to resist asking what is making the difference and becoming interested in it themselves.” – Your smiling sister rebounder. Loraora
“I started using my rebounder the week of July 18. I have had some problems over the last six weeks which kept me from working out and dancing. After testing it out for a few minutes, I decided to try it for 15 minutes. I am a 53 year old belly dancer so my ankles are pretty strong ( been dancing a little over a year). I did feel sore at first. Since that date I have been using it for 30 minutes twice a day because I found that I like it very much. With this rebounder, I have not needed to use any of my other equipment. Also, I have had problems with spinning around when I belly dance. The rebounder helps me with that. I am able to turn around on it very fast and do not feel as dizzy as I use to feel when I am dancing. So, it also is helping me with my dancing. The weight lost was a surprise. I enjoy this rebounder very much. It is also easier using hand weights while jumping of it. I have never been able to do jumping jacks without pain. Now, no pain. I love it.” – Jean
“I have been shopping through Tropical Traditions since Jan. 2005 and have found them to be an outstanding company in every aspect of their business. They are prompt to respond to questions or to rectify any errors and it is always done with respect and kindness. Their products are excellent and I am able to purchase many of the same organic products at a better price than I can purchase them at the store, and I save the time and money of driving to the store. They also offer excellent products of their own that can’t be purchased locally. I promise you will not be disappointed. They are tops in my book!” – Shirley – Delaware, OH
