How Does an Anti Gravity Treadmill Work?

When you hear the term “anti-gravity treadmill,” the very first thing that usually comes to mind is science fiction. It appears to be more of a notion than a fact. Anti-gravity treadmill exercise has been termed the most recent type of prehab in the industry for future-proofing your body from injury while saving you money on physio bills.

The anti-gravity treadmill, also recognized as a no gravity treadmill, can help individuals accomplish rehabilitation therapy with little distress. With this great treadmill, people can run or walk at a lower proportion of their body weight. A few even argue it’s the same weightlessness as being on the moon.

Training sessions on the Anti-Gravity Treadmill are fun for everyone, even those who despise exercise due to fatigue or mobility issues. Many people look forward to using the Anti-Gravity Treadmill. As a result, they are one of the costliest treadmills on the market today. If you are wondering How Does an Anti Gravity Treadmill Work, then this is the article for you.

What is an Anti Gravity Treadmill?

Anti-gravity treadmills, also recognized as zero gravity treadmills, are specialized pieces of equipment that simulate weightlessness by delaying your body into an expandable position. You can go as high as you wish or vice versa, as well as the coils, which will give you the sensation of moving under air pressure. When you start moving forward with the treadmill, the belt will progressively begin to pull you along.


Robert Whalen, a NASA Ames Research Institute biomechanics specialist, created the “anti-gravity treadmill” in the 1990s. As an astronaut here on International Space Station (ISS), Whalen was quite well aware of the necessity to counter the bone resorption and muscular atrophy that happens in low gravity.

Astronauts must interact in a routine of physical exercise. On the other hand, the ISS’s treadmill has permanently abandoned a left much to be desired. Rather than relying on gravity, the astronaut is held in place by straps all across the shoulders and hips.

The bungee system cannot recreate the amplitude or different powers experienced by runners on the ground. Running becomes much more extremely stressful as a result.

Sunita Williams, the very first candidate to run the Marathon Bombing in space, clarified her encounter in a NASA news release: “The belts on my shoulder induced my foot to go helpless and unhappy during the sprint race.  In addition, the strap bristled my neck so badly that I had to cover it with moleskin.”

Sean Whalen, an engineering student at the university, finally agreed to resurrect his father’s exploratory treadmill in 2005. His strategy is to use a reduced gravity simulation model to help rehab clients regain their ability to stand, stroll, and run.

The technique has been licensed to Alter G, which would seem to become the first corporation to use the word “anti-gravity treadmill.” AlterG uses advanced information to help alleviate leg and knee injury recovery patients instead of offering weight to astronauts in space.

How Does an Anti Gravity Treadmill Work?

The Anti-Gravity Treadmill, which looks like a bouncy castle for the leg muscles, creates weightlessness through offloading and gradual loading. This treadmill uses air pressure to assist unweight.

To use it, you must put on a pair of very tight neoprene shorts. The Shorts have a skirt that is covered with zipper teeth. You walk within the device’s chamber, which looks like a burst and is zipped shut. This allows the air pressure to encircle and support the lower body.

The body support proportion can be adapted for walking and running whenever the system is adjusted for a specific individual.

The transparent back of the bubble, primarily used in physical rehabilitation clinics, allows the therapist to discover movement and stride dynamics for more therapeutic intervention. Instead of floating within the system, the person maintains constant contact with the treadmill straps.

Other Features

Some other features of an Anti-gravity treadmill are as follows:

  • The bag is attached to the workout machine and encloses the runner’s lower body and moving belt.
  • The Monitors can display more information than a classic treadmill, such as cadence and security forces, as well as stance time and pace symmetry.
  • Choose a maximum speed (18 mph for the Pro 200 model), an uphill angle (up to 15%), and how much load you want to lose.
  • The waist of these neoprene shorts zips up to create an airtight bag.


Even though individuals aren’t always aware of it, air pressure tends to put a massive strain on one’s joints and muscles. Working out in normal gravity circumstances can lead to muscle damage over time, which is often exacerbated when people avoid working out entirely to reduce the pain.

However, not exercising causes stiffening of troublesome joints and results in softened muscles and inadequate heart health. An anti-gravity treadmill gives you the best of the two: cardio advantages with less joint stress.

Benefits of Anti-Gravity Treadmill

While some special tools are either too tricky or not complicated enough to encounter a wide variety of needs, the anti-gravity treadmill’s extendable nature enables widespread applications. Among its numerous applications are:

1. Supports Healing Tissue

There’s been an investigation to assist the use of body-facilitated support structures in rehabilitation for muscular pain like arthritis or for resuming walking after surgical procedures or situations such as stroke. 1 This is due to the Anti-Gravity Treadmill’s ability to rebuild regular walking and running dynamics while supporting healing tissue.

2. Injury Healing

Without surgery, physical therapy is frequently the best way to recover ligament damage and broken bones. The anti-gravity treadmill helps you to stay in shape without exacerbating your initial injury.

3. Safety Regulations

If we’re talking about something serious, like an injury, equipment that generates zero gravity will make some people anxious; however, the workout machine could not be safer. Regardless of your experiences, you may be able to locate a setting that will allow you to achieve the desired safety results.

The anti-gravity treadmill meets all relevant safety requirements and provides an easy ride. It’s also ideal for people who have pulses because it assists them in regaining their balance. Patients can benefit from a non-intimidating and enjoyable workout.

4. Recovery from Surgeries

For those unable to avoid surgery, the extendable resistance pressure of the anti-gravity treadmill enables you to come back as your condition improves progressively, and you will be resolved to force somewhat more challenging each moment. Furthermore, by enhancing circulation and stamina, numerous patients can accelerate their ultimate recovery.

5. Athletic Training

Distance running, in specific, necessitates lengthy daily workouts to construct stamina. The treadmill helps you to put in that moment without causing harm to your bones. Runners can also collaborate on their shape as they have relatively low support, preventing buckling and muscular depletion.

6. Weight Loss

The Anti-Gravity Treadmill helps rehab clients, athletes, older people, and even people who have suffered from brain trauma ensure a steady fitness level by utilizing unweighting technology to decrease a patient’s body weight by up to 60%. The product has the appearance of a bounce house for the leg muscles. When you get on the treadmill, it weighs you and asks how severe you wish your exercise to be.



Anti-gravity treadmills are a wise investment for all those who are intense regarding their nutrition and well-being. The anti-gravity treadmill is an excellent service for people who have restricted mobility and flexibility. It is also an outstanding tool for people who cannot stroll or interact in conventional forms of exercise.
