For the uninitiated, an anti-gravity treadmill is a piece of equipment that allows users to move in an environment where their own body weight is reduced. As per the National Library of Medicine, it is a treadmill "surrounded by an enclosed, air-filled chamber."

Speaking to another person on how the equipment helped him, Renner said that it allowed him to feel "less weight" so that he could get support while walking. He shared the video on Twitter with the caption:

"I now have to find other things to occupy my time so my body can recover from my will. #minduful #intended #recovery."

The anti-gravity treadmill was invented in the 90s

Robert Whalen was the one who invented the anti-gravity treadmill in 1990. A biomechanics researcher at the NASA Ames Research Center, the idea for the treadmill came to Whalen's mind after he witnessed astronauts on the International Space Station exercising for several hours to avoid the loss of bone mass and muscle in microgravity.

The ISS treadmill required users to have straps around their shoulders and hips, making it uncomfortable.

Whalen designed a treadmill that would allow the astronauts to run naturally. This treadmill enclosed the astronaut's lower body in an airtight chamber and lowered the air pressure inside the chamber which pushed down the astronaut, simulating gravity.

The design was patented in 1992. But the idea was later licensed to a company called AlterG and they used the technology to take the weight off of rehab patients recovering from leg and foot injuries.

Those using it have to wear a pair of tight neoprene shorts that have a skirt lined with zipper teeth attached to it. The treadmill's entry is through a hole in the plastic casing and the person needs to zip himself/herself in that so that from the waist down, they are encased in an airtight plastic bag. The treadmill measures weight and asks the way the workout should be.

It is useful in physical rehab clinics and lets the patients exercise without exacerbating an injury.
