Alter G Treadmill

The Alter G treadmill uses differential air-pressure technology originally developed by NASA as a way for astronauts to exercise and maintain conditioning in space. Since then, this technology has been used in medical facilities, hospitals and physical therapy clinics in order to help patients rehabilitate from illness and injuries. This machine is capable of reducing the user’s body weight as much as 80 percent in order to maximize mobility. This equipment can be used on a variety of patients from older adults combating reconditioning to elite level athletes recovering from lower body orthopedic surgeries and everyone in between!

Why should I use the Alter G?


The Alter G is useful in limiting the amount of weight and forces through joints. Clients who are rehabbing from an injury and can’t fully bear weight on an extremity, find that the Alter G is useful in helping return to proper walking and running form. High performance athletes also use the Alter G when training; runners will work Alter G sessions into their training regimens to allow for longer distance runs without the wear and tear that occurs when running outside or on a regular treadmill.
