    Rebounding is a unique exercise in that you achieve a weightless state at the top of each jump then land with twice the force of gravity on each bounce. This twice-gravity bounce affects every muscle and cell of the body. Researchers at the University of Kentucky, in conjunction with NASA, concluded that “the magnitude of the biomechanical stimuli is greater with jumping on a trampoline than with running.”

    NASA did research back in the late 70s and 80s, and it discovered that astronauts, after some time in space, would lose close to 14-15% of bone mass. One way the scientists believed that astronauts could get the appropriate strength conditioning to counteract this loss was from rebound exercise. Their research indicated that rebounding was 68% less traumatic to the musculoskeletal system than jogging on a hardwood surface or cement surface. So, their study really gave credibility to rebound exercise as a non-jarring exercise and as something that could maintain the strength of the bones.
    Besides eating a balanced diet, the single most beneficial thing you could do for your health is “cellular-exercise.” And that’s where gravity plays a large part in boosting the immune system.

    Rebounding is also a cellular exercise. The body has sixty-five to maybe eighty trillion cells. Cell strength is enhanced by jumping up and down on the rebounder because of the added G-force of your own body weight. The cells become more resistant and stronger and your immunity is enhanced.

    According to researcher Albert Earl Carter, “Every cell in your body does need exercise and will benefit from activity.” The basic component of any and all exercise is gravity and the body’s ability to react to its pull – or opposition. This reaction is strength-building, down to the very smallest of cells. Theoretically, if one were to subject himself to twice the normal force of gravity (2 Gs), he would become twice as strong. And not just muscular strong, but strong on a cellular level. Stronger cells are healthier, more resilient disease-fighters.

    Because the cells in the body live in an essentially zero-gravity environment, it is necessary to alter the G-force in order for fighting immune system) to reap the full benefits of exercising. Jogging, swimming, or other exercises cannot do this, as they cannot offer the consistent change in gravitational force that is needed. As NASA discovered, rebounding is the only exercise proven to exert the right amount of “pull” on the human body down to the cellular level.

    Some unique things happen at the cellular level when rebounding. Unlike jogging or any other activity which places only portions of the body in a cycle of changing G forces, rebounders change the G forces from 0 up to 2 or more Gs on each bounce cycle. Some of the cellular changes expected with any good exercise program are: the performance and circulation of the heart, lungs, and lymphatic system are dramatically improved, while the muscle tone and skeletal mass enjoy healthy increases. An additional plus is an almost total lack of injuries seen with many other aerobic activities.

    Regular exercise helps prevent clogging of the arteries and lessening of cardiac performance. Exercises like rebounding that work the leg muscles help keep the blood moving. The contractions of these muscles (the calf muscles in particular) during exercise act like pumps to circulate the blood back up to the heart for fresh oxygen.

    For somebody really out of shape who has not exercised in quite some time, or for elderly people or seniors, they need to start out with very, very mild exercises. It’s best to have them work with a physical trainer or personal trainer rather than sticking them in a rebounding fitness class with forty people.

    For an athlete, rebounding helps you become grounded and rooted. Whether you are a baseball player, a racquetball player or a tennis player, you want to take energy from the ground. Power comes from a grounded stance.

    For people with either catastrophic or mild injuries needing rehabilitative exercise, you can still do rebound exercise, but need a trainer. If you have any slipped disc or back problems, you should consult a physician.

    Unlike other methods that require expensive equipment, membership to health clubs, or a lot of sweat and strain – along with injuries from time to time – REBOUNDING is safe and designed to be easy on your body from the start, building endurance and strength without any threat of the damage that can result with most other exercise programs. Because it is pleasant to use and can be done in your home, you’ll also find it easy to continue your progress toward becoming the image of good health.
    Some exercises can actually do harm while doing good. Researchers have discovered that jogging and other activities that place a lot of impact on the legs can, over time, cause the skin to actually sag. For this reason, such exercisers have a tendency to develop jowls, sagging breasts, and the like over years of practicing their sport. If your goal is to avoid looking old, then jogging may not be the exercise of choice. Additionally, runners often suffer a number of injuries brought about through strains on their feet, ankles, and knees, as well as falls.

    Walking is more ideal in terms of safety and avoidance of aging skin, but it’s not so ideal from a time standpoint. You have to devote far more time walking to gain the health benefits of exercise ( or add weights to the routine to achieve the strenuous activity needed to burn fat). Additionally, “walking has little effect on building muscle mass and strength,” noted researchers at the Mayo Foundation for Medical Education and Research. So, while walking can be a useful addition to a good exercise program, it fails to be an ideal exercise for actually building up your strength or shedding fat unless you have lots of time to spend at this activity.

    Bicycle riding isn’t without its drawbacks, either. Bicycling is often dangerous in areas with heavy car and truck traffic. It also fails to build muscles in areas of the body other than the legs. For men there are added problems. Recent research has found that bicycling will cause impotency and prostate problems with time for most, it not all, male riders. For women, bicycling fails to reduce bone loss or calcium depletion from the skeletal system, making it less than ideal for preventing osteoporosis in later years.

    Sports is more start and go than continuous. This places intense strain on the heart while doing nothing to burn off body fat by failing to sustain activity beyond 20 minutes at a stretch. You goal should be a continuous moderate exercise session instead of one that entails sudden spurts of heavy exercise followed by long lulls. Many team sports are bad for this reason: they place your heart under intense and potentially damaging strain for a few moments followed by minutes of inactivity. Competitive sports, races or other forms of competition are also best avoided for these reasons since they encourage you to put excess strain on your body.

    Free weights, “bow,” spring-loaded weight machines, and true weight machines offer a good way to build muscle and bone mass. But, by their nature they dictate massive and often expensive weights, barbells, and/or machinery that take up a lot of room. They often produce poor aerobic results by failing to keep activity at a constant, sustained level for more than 20 minutes. In the case of free weights, they demand the availability of a spotter if one is to avoid dangerous injuries. By themselves, free weights have a lot of handicaps. (However, as we’ll see, it is possible to add elements of free weight exercise to our proposed program with little expense and no risk of injury.)

    During that time your muscles will do some intense lifting, building up as if you had been working out with much heavier free weight. It doesn’t feel intense. It lasts only for a fraction of a second, but the work is still being done, even it you’re almost unaware of it. This scientific use of G forces in exercise gives you the benefit of lifting a heavy weight without the dangers. And because you’re also bouncing to maintain this effect, you obtain the aerobic effect equal to that of jogging or other moderate workouts. In short, you’re getting the best parts of all possible exercises.

    Preventable cancers account for more than 40 percent of all cancers among women. ‘Cellular exercise’ boosts the body’s ability to fight toxic invaders – including cancer.

    Rebounding is an effective exercise that reduces your body fat; firms your arms, legs, thighs, abdomen, and hips; increases your agility; strengthens your muscles overall; provides an aerobic effect for your cardiopulmonary systems; rejuvenates your body when it’s tired, and generally puts you in a state of mental and physical wellness. A 150-pound person spending one hour on a rebounder will burn about 410 calories; the same person jogging for one hour (at the pace of five miles per hour) will burn only 355 calories.

    The more and the longer you do rebounding the better. 5 minutes is better than 3 or 30 better than 10. You have to find your own routine and do it every day or at least 3-4 times a week.

    With rebounding, you are exercising from the inside out. If you’ve been wanting to get into shape or shed those pounds that it seems like you just can’t shake, rebounding will do the trick for you. After just a few weeks or even days, you’ll start to see a difference and feel better.

    People who rebound find they are 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 effectively stimulates the lymphatic system without trauma to the musculoskeletal system. This unique discovery is central to the reasons Rebounding has become one of the most beneficial forms of exercise ever developed.

    The capacity of the lungs also increases, enabling them to process more air and replenish oxygen in the cells of the body’s tissues and organs more quickly. Metabolism (conversion of food into energy) is enhanced and you tend to absorb nutrients from your food more efficiently. Any tendency towards constipation, kidney stones, or diabetes is reduced by this form of exercise.

    Rebounding Has Anti-Aging Benefits – One of the primary causes of the physical deterioration associated with aging is the declining performance of the heart and circulatory system. The pumping force of the heart decreases by 8% per decade in adulthood; lung capacity decreases, muscles lose strength, reaction time slows, and bones lose their mineral content. Exercise can help halt or at least slow this aging process.

    Dr. Akselsen has seen some remarkable results from her rebounding therapy. Children who had been unable to express themselves during their first 15 years of life, having a vocabulary of only a few words, were able, after a month or two of therapy, to speak in complete sentences and express their thoughts. “When the physical defect is corrected, the mental defect is also corrected,” concludes Dr. Akselsen.

    Rebounding also benefits brain-injured children, according to a German study involving 20 patients. Trampoline therapy was judged to be a useful part of their medical rehabilitation treatment, producing improvements in standing balance and movement coordination.

    Rebounding Improves Breathing in Cystic Fibrosis – A Norwegian study examined the effects of rebounding on eight children, age 10 to 13, with cystic fibrosis (CF). This is a hereditary disease affecting ducts in the pancreas, sweat glands, and lungs, in which the ducts get clogged with thick mucus and cannot work properly. Children exercised on rebounders for 109 minutes weekly for two months.

    Two of the children with the most advanced lung problems increased their oxygen intake from 45 to 49 ml/kg/minute. In addition to providing this benefit, researchers recommended rebounding to CF patients as a way of breaking the monotony of their standard physical training programs.

    Emphysema patients pulmonary function improved by very gentle rebounding.The physical therapy department at the University of Michigan medical school reported, about 1980, that the very mild up and down motion from gentle rebounding on a mini-trampoline would very significantly improve the functional breathing capacity of people with severe emphysema.

    Unlike the circulatory system, in which the heart pumps our blood, the lymphatic system does not have a pump. It is a one-way valve, and the lymphatic system only works efficiently if three things take place: 1) exercise, 2) massage, and 3) gravity. I don’t know of any other exercise or form of movement that will work those three simultaneously other than rebounding. It helps the lymph system pump the uric acid, and other toxins from the tissues into the bloodstream efficiently and quickly.

    Exercises like rebounding that work the leg muscles help keep the blood moving. The contractions of these muscles (the calf muscles in particular) during exercise act like pumps to circulate the blood back up to the heart for fresh oxygen.

    The added benefit of having the lymphatic system energized during rebounding can’t be overemphasized in terms of achieving better total health. Dr. Arthur C. Guyton, Professor and Chairman of the Dept. of Physiology and Biophysics, University of Mississippi School of Medicine, is recognized internationally for his expertise on lymphology and the lymphatic system. He had this to say about the importance of exercise:

    “The lymphatic group becomes very active during exercise but sluggish under resting conditions. During exercise, the rate of lymph flow can increase to as high as three to fourteen times normal because of increased activity.”

    Dr. Robert G. Frost, who headed the research team, said this about rebounding:

    “It improves the performance of the heart, lungs and lymphatic system. It improves circulation and muscle tone and challenges the skeletal muscles to increase stamina without any of the jarring associated with other aerobic activities. Gravity-plus rebounding is the single most efficient way to improve health. No other exercise can match it.”

    Researchers also have discovered that on a cellular level, more benefits are realized by rebounders. Dr. Frost explains, “ Lymph system cleanses out toxic waste and health-threatening bacteria. What bouncing does is improve the body’s own immunological system.”

    In other words, those who use a rebounder have bodies more capable of dealing with bacteria, viruses, and toxins produced by these organisms, making the user much more resistant to disease than he would otherwise be.

    Rebounding Helps Move the Lymph One of rebounding’s special benefits is its ability to improve flow in the lymphatic system. “The lymphatic system is the metabolic garbage can of the body,” says Dr. Walker. “It rids the body of toxins, fatigue substances, dead cells, cancer cells, nitrogenous wastes, trapped protein, fatty globules, pathogenic bacteria, infectious viruses, foreign substances, heavy metals, and other assorted junk the cells cast off.”

    Stagnant or inadequate lymph flow is associated with the onset of many symptoms and illnesses, including bursitis in the shoulders, bunions, joint stiffness or soft tissue spasms, dry flaking skin, bad breath, body odors, lethargy, depression, and cancer. Unlike the circulatory system with the heart as its pump, the lymph system lacks a pump to move the fluid. It is vital that the lymph fluids continue to flow in order to eliminate waste from the body. The flow is dependent on muscle contractions and body movements, massage and other forms of compression, and gravity. One of the best ways to stimulate this flow is by exercising.

    The lymph system consists of lymph nodes which are clusters of immune tissue that work as filters or “inspection stations” for detecting foreign and potentially harmful substances in the lymph fluid. Acting like spongy filter bags, lymph nodes are part of the lymphatic system, which is the body’s master drain. While the body has many dozens of lymph nodes, they are mostly clustered in the neck, armpits, chest, groin, and abdomen. Lymph fluid (1-2 quarts) accounts for 1-3% of body weight. Exercise can increase lymph flow by 15 times.

    “The lymphatic [flow] becomes very active during exercise but sluggish under resting conditions,” states Arthur C. Guyton, M.D., chairman of the department of Physiology and Biophysics at the University of Mississippi School of Medicine and author of Basic Human Physiology. “During exercise, the rate of lymph flow can increase to as high as 14 times normal because of the increased activity.” This happens because the lymph ducts expand during rebounding. The increased lymph flow flushes more toxins through the lymphatic system. Or as Dr. Walker says, rebounding stimulates “an optimum drainage of the lymphatic circulation.”

    Because rebounding exercise takes place in the privacy of your home, you’ll pocket a lot of ectra cash since you’ll do away with the need to pay membership fees at health clubs as well as the gas and time needed for that long drive to the gym.

    Another important aspect – rebounding is fun, and that makes it more likely that you’ll do it.
