About  by 



Rebounding on a Needak RebounderNeedak® rebounders are proudly manufactured in O'Neill, Nebraska by Needak Manufacturing, the only firm still producing rebounders in the United States.

Needak Manufacturing was founded in early 1990 with the mission of producing the best rebounder available.  Prior to the founding of Needak Manufacturing, rebounder manufacturers had been leaving the United States in search of lower manufacturing costs in "low cost countries", primarily in Asia.  Although of lesser quality, these imported rebounders forced remaining manufacturers either overseas or out of business.  In the past 20+ years, Needak® has established itself as the premier rebounder, with the highest quality and best jumping platform available.

Unlike other manufacturers, Needak® produces only rebounders.  Where other brands are produced in multi-use overseas contract manufacturers, rebounders are the only focus of Needak® Manufacturing.

Several fitness industry leaders, including Al Carter, the father of rebounding, have endorsed Needak® rebounders as being in a class by themselves compared to other rebounders in terms of design, manufacturing quality, and quality of bounce.

We firmly believe that Needak® rebounders are the finest on the market and that a Needak® rebounder will provide you and your family a unique low-impact exercise for years and years.

Below are some general testemonials and endorcements. Be sure to read the reviews from our customers here: Needak® Rebounder Reviews (click and scroll down for reviews)

“I was recently diagnosed with MS. I changed my diet and exercise with the rebounder 1 to 3 times a day. I have lost 15 pounds and everyone says I look so healthy. I feel that the rebounder has given me strength. I have my 66 year old mom using it, and I even put my one year old daughter on it – she loves it!” - L.D., TV Writer/Producer, Amity Harbor, NY

 “I had bone spurs on both my heels for about 15 years and needed arches in my shoes so I could walk comfortably. I also had a calcium build up on my fifth vertebrate in my back. After using the rebounder for only three weeks – my spurs had totally disappeared; my neck took a little longer. I have now had my rebounder for over 4 years and enjoy using it everyday. Again, a big THANK YOU! - H.M., Edmonton, Canada

 “I keep my rebounder at the foot of my bed and use it daily.” - Bob Hope

 “The rebounder is great! I lost 8 lbs and beat my 6’3’’, 180lb boyfriend at arm wrestling after only 2 months of use! Then he started bouncing and his masseuse asked him, ‘I know you’ve been working out for 2 years -  what have you been doing the past week?’ She actually felt the difference in his muscles!” - B.L. New York, NY

 “Rebounding exercise is the best exercise in the world! Now that I’ve tried rebounding, I have progressed more in 2-3 months than in 3 years on the Nordic Track. My primary exercise, and the one I now recommend to my patients, especially for upper body shaping and toning, overall cell exercise and health, and just plain fun, will now be the rebounder.” - Dr. R.P., Nashville, TN

 We have had the Needak® Soft-Bounce™ for about two weeks or so. My wife’s pain in her hips and arms has completely disappeared. - A.L., Cave Junetson, OR

 “My wife and I learned of your rebounding product approximately two years ago, and have been using it ever since. First one unit, then two -  then three units. We keep them handy on all floors of the house and find its convenience exceeds by a factor of ten any other exercise product. Just by doing ten minutes in the morning, or even five, or even three minutes while watching the news and weather, you are awake and feeling just great. No other exercise can offer that. Then for the evening pickup, after a long day, again – the recirculation of the blood facilitated by your rebounder cannot be achieved in any other exercise procedure or equipment that we are aware of, and we have tried them all. The rebounder speeds up metabolism and thereby burns calories faster and serves as a weight control device which has no equal. I simply cannot praise the concept and your particular product line more highly.” - L.P., Publisher Ohio, USA and Zurich Switzerland

 “The Needak® Soft-Bounce™ rebounder is a smile generating device. Who would want to do without it for even a single day?” - J.Q., Richland Center, WI

The Needak® Soft-Bounce™ rebounder is the same high quality Needak® rebounder that J.B. Berns recommends for gym use. - “Urban Rebounding” by J.B. Berns


“The Needak® Soft-bounce™ IS the standard of rebounders! Well made, comfortable and practically indestructible it is the only rebounder I recommend in my books’ exercise sections.” - Marie Miczak, D. Sc., Ph.D., Author of “How Not to Kill Yourself with Deadly Interactions” & “Age Reversal for Mind and Body”


Hello. I'm Joseph Ventura, DC, Chiropractic Physician with 21 years experience in the field of exercise rehabilitation. In those years I've seen and used just about every type of exercise routine and devices designed to improve cardiovascular health. By far, the winner in the "benefits versus risks" category is rebounding.
When discussing aerobic exercise you must understand the difference between High Impact and Low Impact and how those differences affect the body.

High Impact Dangers

Everytime the foot hits the ground, force is generated by the impact. Some of this force travels down and out, absorbed by the shoe and the ground. Some of the force travels back upwards to be absorbed by the foot, ankles, knees, etc. The higher the impact, the more force is absorbed by the body.

While a sudden injury rarely occurs during this type of injury, microtraumas, or very slight cumulative injuries, do occur frequently. Over time these little injuries can become big problems.

The most likely place for a major problem to develop is in the cushions of major bones, the meniscus of the knees, and the disks of the spinal column.

The animation on the right shows how the bony spinal segments (vertebrae) can break down from excessive wear and tear.

Degenerative Joint Disease can occur
from repetitive high impact exercises.

The Low Impact Difference

To reduce the chance of these microtraumas developing into big problems, the goal is to focus on activities that produce high aerobic benefits and low impact forces.

By far, the best exercise routine to fit this bill is rebounding on a mini-trampoline. If done properly, virtually every major muscle in the body, especially the heart, is worked with extremely low impact to the knees and spine.

As always, consult your physician before starting any new exercise routine.


Most important for excellent rebounding is the mat material. It should give no stretch during the downward landing, while at the same time providing a resilient rebound. Such a mat will be made from Permatron® material, which has a smooth finish. The Permatron® is resistant to ultraviolet rays, doesn't break down as do other fabrics, and allows no moisture absorption. Part of the specifications for a perfect rebounder is that its mat will be sewn together using 5760 stitches of high-grade nylon thread with two layers of strong polypropylene webbing stitched around the mat's edges.

Attached to a heavy-grade, all steel round frame should be an oversize spring mechanism holding four-inch-long, custom-made jumbo springs which deliver a soft bounce. Thirty-six springs made of quality wire will hold the mat to the frame. The springs should be shielded by a protective cover. Individual spring mounting pins prevent frame wear. Tapered coils help to give extended wearability to such springs. (Untapered coils allow low-quality springs to break frequently, requiring replacement.) Replacement springs must be available directly from the manufacturer since retail distributors seldom stock spare springs.

The spring-loaded legs should fold for easy storage under a bed or behind a door. For a folding rebounder, the frame should fold in half to be packed into its carrying bag, allowing for storage in a car trunk.

To jump for health, rebounding devices that exhibit all of these features of excellence I’ve been describing are the Needak® rebounders. They meet all of these specifications for the ideal rebounding device.” - Dr. Morton Walker, author of JUMPING FOR HEALTH.

Jumping for Health
by Morton Walker, D.P.M.

In the spring of 1981, 28-year old Samuel J. Kofsky of Manchester, New Hampshire, a Ph.D. candidate attending the School of Economics at Dartmouth University, lay in a Hanover, New Hampshire hospital room, recovering from the surgical excision of an apparent cyst. Soon after the operation, his surgeon and an oncologist entered the room and walked hesitantly to the foot of the patient's bed. The surgeon said, "Sam, I don't want to shock you, but our hospital pathology department reports that your biopsy shows you have a connective tissue cancer. It's a rare form of fibrosarcoma, which develops suddenly from small bumps on the skin like what I thought was your cyst. Sam, I'm sorry to tell you that there's an 80% chance it will take your life within four years."

The oncologist had come along to confirm the young man's diagnosis and prognosis. Then he suggested further treatment.

Soon Sam Kofsky found himself faced with daily radiation therapy and then intravenous chemotherapy which the late Senator Hubert H. Humphrey had once referred to during a TV interview as "bottled death!" For graduate student it was devastating treatment routine. He felt that his body being assaulted, burned, and poisoned.

To sustain himself through chemotherapy, and to believe that he was doing something positive to help himself, Mr. Kofsky took up exercise of the aerobic type. Aerobics is the steady state of exercising which, when performed over a period of months or years, develops the cardiopulmonary system's ability to take in and utilize more oxygen. This elevated amount of "oxygen uptake" increases cellular metabolism of oxygen molecules as nutrients. Besides competitive team sports such as football, basketball, racquetball and tennis, aerobic exercises include speed walking, running, sustained jogging, swimming, rowing, bicycle riding, calisthenics performed in a specific time frame, and rope jumping.

As it happens, Mr. Kofsky became intrigued with rebounding, which is similar to jumping rope except that it's performed on a kind of mini-trampoline (see Photograph 1). Since the jumping surface of a rebounding device has cushioning spring to it, any jarring to one's ankle joints, knees, and back is removed. While rebounding, too, a person can work out outdoors or indoors and simultaneously speak on the telephone, watch television, listen to music, and do other things. Jumping on the mini-trampoline is the ultimate aerobic exercise able to be performed anywhere, even in hotel rooms with a carryon, foldable-type rebounding device As he was being treated with toxic chemicals, Mr. Kofsky engaged in rebounding for his health several hours every day, including 60 minutes before breakfast, lunch and dinner. Whenever possible, he carried his rebounding device out-of-doors to bound under the trees. Also he ate a nutritious diet, took supplements, and engaged in other exercises for diversity. At regular intervals he swam a full mile at the local health club, furiously punched the heavy bag, and ran a consistent six-minute mile over a ten-mile course. His weight plummeted 36 pounds from a high of 193 not from cancer, but from his strenuous amount of daily exercising.

The exercise was good psychologically for Mr. Kofsky, since so much activity had him believing that he was "winning" his battle against cancer. Philosopher Michael Novak has described winning as "a form of thumbing one's nose, for a moment, at the cancers and diseases that, in the end, strike down all of us." The patient pushed himself harder each day. By the end of a year, he had doubled his daily rebounding time and was seemingly able to go into a meditative state even as he bounced on the device. Mr. Kofsky additionally increased the number of swimming laps, miles run, and time punching the bag. He gained a new confidence.

Since he needed to research his Ph.D. thesis, later the student was forced to drop back on his two more time-consuming sports at the gym and swimming pool. But he never diminished the amount of his jumping for health, because he traveled with a portable rebounder which folded into its own airplane carryon bag.

I met Sam Kofsky 120 feet below the ocean's surface at Grand Cayman Island when we buddied during a morning scuba dive on the North Wall's underwater drop off. Returning aboard our dive boat, he enthusiastically told me of his involvement with rebounding. I told him then of my having authored a book on the same subject. We met often during that vacation trip and spoke about other alternative methods of healing. Our conversations took place in January 1995, and we've stayed in touch since. Kofsky, now age forty-two, had already lived well past his prior dire prognosis. He attributed the circumstance of his thriving to his jumping for health and life.

The same time that he took chemotherapy and engaged in his prolonged exercise therapy, the Dartmouth student finished his doctoral thesis. He is now an assistant professor of economics at a midwestern university. Dr. Kofsky needs no chemicals for cancer and feels fitter than ever today. Perhaps the malignancy still lurks somewhere in his body, for once cancer has been present the potential for its return always remains. Still, this economics professor knows that he has fought it off the best way he could. Dr. Kofsky continues to rebound and participate in other sports activities.

Rebounding Benefits the Body in 30 Healthful ways

Rebounding is an exercise that reduces your body fat; firms your legs, thighs, abdomen, arms, and hips; increases your agility; improves your sense of balance; strengthens your muscles over all; provides an aerobic effect for your heart; rejuvenates your body when it's tired, and generally puts you in a state of health and fitness.

You can easily perform this exercise in your living room, your office, and your yard. The traveler may wish to carry a portable rebounder aboard an airliner for use in a hotel room. It's the most convenient, metabolically effective form of exercise around.

There are 30 health advantages of regular rebounding, including the following:

1. It increases the capacity for respiration.
2. It circulates more oxygen to the tissues.
3. It establishes a better equilibrium between the oxygen required by the tissues and the oxygen made available.
4. It causes muscles to perform work in moving fluids through the body to lighten the heart's load.
5. It tends to reduce the height to which the arterial pressures rise during exertion.
6. It lessens the time during which blood pressure remains abnormal after severe activity.
7. It holds off the incidence of cardiovascular disease.
8. It increases the functional activity of the red bone marrow in the production of red blood cells.
9. It aids lymphatic circulation, as well as the flow in the veins of the circulatory system.
10. It encourages collateral circulation.
11. It strengthens the heart and other muscles in the body so that they work more efficiently.
12. It allows the resting heart to beat less often.
13. It lowers elevated cholesterol and triglyceride levels.
14. It stimulates the metabolism.
15. It promotes body growth and repair.
16. It tones up the glandular system, especially the thyroid to increase its output.
17. It adds to the alkaline reserve of the body which may be of significance in an emergency requiring prolonged effort.
18. It chemically attains absolute potential of the cells.
19. It reserves bodily strength and physical efficiency.
20. It expands the body's capacity for fuel storage and endurance.
21. It improves coordination through the transmission of nerve impulses and responsiveness of the muscle fibers.
22. It affords muscular vigor from increased muscle fiber tone.
23. It offers relief from neck and back pains, headaches, and other pain caused by lack of exercise.
24. It enhances digestion and elimination processes.
25. It allows for better and easier relaxation and sleep.
26. It results in a better mental performance, with keener learning processes.
27. It curtails fatigue and menstrual discomfort for women.
28. It minimizes the number of colds, allergies, digestive disturbances, and abdominal problems.
29. It tends to slow down aging.
30. It reduces the likelihood of obesity.

How Rebound Exercise Accomplishes Its Benefits

Rebounding involves aerobic movements performed on a bouncing device that looks like a small trampoline. It has you jumping up and down for health and fitness. As an ideal jumping device, the mini-trampoline or "rebounder," has a strong woven mat attached by coiled steel springs to a circular steel frame. The rebounder usually is round, although some models have been made oval, rectangular, square or polygonal. The entire jumping surface of the mat is twenty-eight inches in diameter, stands on six legs with spring coils of their own, which are seven to nine inches high.

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 doublegravity 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. It's likely that the vast amount of oxygen taken in by Dr. Samuel Kofsky over a sustained period was the true source of his cancer remission. Rebounding might be considered a precursor movement for better achieving the oxygen therapies.

Rebounding offers a less stressful means of reducing body fat and simultaneously firming body tissues. Running in place on the rebounder burns calories effectively. According to a person's body weight, Table A shows how many calories from running on the rebounder may be expended per specified period of time in minutes.

The Detoxification Effect of Rebounding

The lymphatic system is the metabolic garbage can of the body. It rids you of toxins such as dead and cancerous 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

James White, Ph.D., director of research and rehabilitation in the physical education department at the University of California at San Diego (UCSD), has explained how jumping for health offers a true physical strengthening effect to the muscles. He said, "Rebounding allows the muscles to go through the full range of motion at equal force. It helps people learn to shift their weight properly and to be aware of body positions and balance."

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 (see Table A). "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.

As illustrated and explained in my book, Jumping for Health, there are 33 different exercises that may be performed advantageously on the rebounding device. Eight popular rebound movements are shown below.

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.

Specifications for the Perfect Rebounder

Depending on the quality, rebounding devices may be relatively low in cost, especially a department store model that's no more than a toy. Bouncing on such poorly-constructed models, usually imported from Asia, may actually be harmful to one's muscles, joints, and nerves. There's no yield to them and the abrupt jarring effect is the same as landing on the floor. My recommendation is that one should avoid purchasing these cheaply priced models.

Rebounding devices can be acquired from sporting goods stores, department stores, by mail order, and in some health food stores. No one manufacturer has a lock on the market for rebounders, but some are better manufactured than others. It's best, perhaps, to purchase your exercise unit directly from the manufacturer. (See Resources.)

Most important for excellent rebounding is the mat material. It should give no stretch during the downward landing, while at the same time providing a resilient rebound. Such a mat will be made from Permatron® material, which has a smooth finish. The Permatron® is resistant to ultraviolet rays, doesn't break down as do other fabrics, and allows no moisture absorption. Part of the specifications for a perfect rebounder is that its mat will be sewn together using 5760 stitches of high-grade nylon thread with two layers of strong polypropylene webbing stitched around the mat's edges.

Attached to a heavy-grade, all steel round frame should be an oversize spring mechanism holding four-inch-long, custom-made jumbo springs which deliver a soft bounce. Thirty-six springs made of quality wire will hold the mat to the frame. The springs should be shielded by a protective cover. Individual spring mounting pins prevent frame wear. Tapered coils help to give extended wearability to such springs. (Untapered coils allow low-quality springs to break frequently, requiring replacement.) Replacement springs must be available directly from the manufacturer since retail distributors seldom stock spare springs.

The spring-loaded legs should fold for easy storage under a bed or behind a door. For a folding rebounder, the frame should fold in half to be packed into its carrying bag, allowing for storage in a car trunk.

To jump for health, rebounding devices that exhibit all of these features of excellence I've been describing are the NEEDAK® Soft-Bounce™ rebounders. They meet all of these specifications for the ideal rebounding device. The stabilizing bar is an optional accessory that is easily attached to the NEEDAK® rebounder.
