The Alter G Anti-Gravity Treadmill, which uses NASA Differential Air Pressure technology, is a dependable, cutting-edge rehabilitation and training tool. The International Space Station astronauts who used it at first were able to exercise for hours every day to prevent their muscles and bone mass from deteriorating while they were in microgravity.

How Do Anti-gravity Treadmills Operate?

The patient is helped to unweight by the Alter G Anti-Gravity Treadmill. Specified shorts are typically worn on top of shorts or form-fitting leggings. After doing so, the patient is zipped inside the machine’s chamber, which resembles a sizable bubble. This enables the air pressure to enclose and support the lower body. The body support percentage can be changed to your liking once the machine has been calibrated to the user. The treadmill then functions as a standard treadmill with walking and running speed adjustments. The physical therapist can observe mobility and mechanics for better treatment because the back and sides of the bubble are transparent.

The Alter G Anti-Gravity Treadmill can be used to support the healing tissue while also restoring normal walking and running mechanics. It can also be used to help people lose weight and recover from fractures, stress fractures, knee or hip replacement surgery, or both. Overall, using this can speed up recovery, facilitate rehab, and maximize rehab.

Currently, we have Alter Gs in both of our Massachusetts offices, which are in Woburn and Melrose. Alter G minutes are a stand-alone cash service that may or may not be covered by your insurance.

What Does An Anti-gravity Treadmill Do?

With an anti-gravity treadmill, you can exercise at a lighter bodyweight than usual, which relieves pressure and is excellent for weight loss, injury recovery, and rehabilitation of overworked joints and muscles.

With anti-gravity treadmills, your bodyweight is reduced using a pressurized air chamber. Your lower half fits inside the air chamber, which is closed with a zipper, and the apparatus adapts to your weight, letting you choose how much weight support you want from the apparatus. Similar to regular treadmills, the pressurized air chamber on this treadmill facilitates movement and lessens discomfort.

The Cost Of Anti-gravity Treadmills

Treadmills designed to combat gravity aren’t like those used in homes or even gyms. Costing around $35,000 to $75,000, they’re some of the most expensive training machines on the market.

University sports centers and physical therapy clinics are the typical places to find anti-gravity treadmills. You can rent it for a single session; the hourly rate typically ranges from $50 to $80.

The History Of Anti-gravity Treadmills

NASA has been launching astronauts into space for over 50 years. As missions got more complicated and technology advanced, astronauts were spending more time in orbit. The typical astronaut could stay in space for three to six months, depending on the mission.

These daring space explorers’ muscles and bones begin to atrophy without the literal pull of earth’s gravity.

Astronauts must exercise frequently to maintain their bone and muscle strength. Why is it important? Without physical exercise, their bodies, sooner than later, will start losing both muscle and bone density.

This results in a loss of size and strength and, by weakening them, can jeopardize the astronauts’ capacity to carry out tasks in space. And, God forbid, they would need to be in excellent shape in an emergency so they could escape the danger as quickly as possible.

In addition, the astronauts’ weakened muscles and bones will make carrying any weight painful and difficult once they return to Earth.

For these reasons, NASA (as well as other space agencies) has worked diligently over the years to develop strategies and tools to support astronauts’ physical well-being.

Then, in the 1990s, Dr. Robert Whalen, a biomechanics researcher at the The task of creating a way for astronauts to exercise inside the space station fell to NASA Ames Research Center.

A pressurized bubble that used air pressure to hold the astronauts down was one of the tools he created. Anti-gravity treadmills as a concept were thus created.

It was an easy process. The astronauts’ lower bodies were originally enclosed in an airtight chamber where the air pressure was elevated, forcing them downward and creating the illusion of gravity.

This, in turn, increased the astronaut’s apparent weight, allowing them to exercise at their normal earth weight.

This was a big step. With the previous devices, the astronauts could only train at roughly 60 percent of their body weight on earth. The astronauts could now recreate Earth-like conditions in space, however, thanks to the new device.

However, due to funding limits, NASA decided to pursue some of Robert’s other ideas, and his “air-pressure” controlled treadmill never really caught on.

Then around 2005, Sean Whalen, Whalen’s son made the decision to resurrect his father’s experimental treadmill. Sean wanted to make it possible to lessen gravity on Earth rather than increase it.

Then, by flipping the air pump, thus, creating the opposite gravity effect, Sean designed the initial prototype of the anti-gravity treadmill as we know it today.

The Technology Behind The Machine

The reason anti-gravity treadmills can “manipulate” gravity comes down to the innovative “Differential Air Pressure” (DAP), a gravitational force-resisting technology.

Anti-gravity treadmills feature a bubble that inflates with air, then surrounds the user’s lower body. This gently lifts them off the treadmill which reduces pressure on the lower body.

You can therefore walk or run as though you weigh only 90 pounds if you weigh 180 pounds and use the anti-gravity treadmill at 50% of its maximum setting.

Would you like to experience what it’s like to shed 30 pounds? 84 percent is the setting to use when lifting 150 pounds.

Is Owning An Anti-gravity Treadmill Worth It?

It’s best to consult with your doctor or physiotherapist before deciding whether you require an anti-gravity treadmill. Anti-gravity treadmills are typically used for joint pain, injury recovery, and rehabilitation, and a doctor may even recommend anti-gravity exercise if they believe their patients will benefit from it.

By evaluating your physical condition, you can decide whether an anti-gravity treadmill is the best option for you. Do you find that doing cardio on standard machines hurts too much, or is it difficult for you to work out because of your size? Do you struggle to recover from recent or ongoing injuries? An anti-gravity treadmill might be the perfect remedy if you said yes to any of these questions.

The Best Anti-gravity Treadmill Stores Where To Go?

Amazon is still the best place to find high-quality home gym equipment at the lowest prices, even though you probably can’t buy an anti-gravity treadmill there. Take a look at their selection of treadmills and benefit from their quick, free shipping.


You ought to try anti-gravity treadmills if you’re dealing with injuries, want to explore more training options, or just want to train in a bubble (no pun intended).
