AlterG Anti-Gravity Treadmill

The AlterG Anti-Gravity Treadmill offers a revolutionary approach to athletic training and rehabilitation. 

From achieving athletic goals to conditioning, to recovering from an injury or surgery, AlterG provides benefits like no other treadmill can. 

The AlterG Anti-Gravity Treadmill helps to maximize your fitness and rehab outcomes by defying gravity, allowing you to regain and develop function like never before. AlterG's patented NASA technology offers a unique differential air pressure that allows for precise partial weight bearing, providing an accurate, safe and comfortable exercise experience.

FDA-approved in 2008, the AlterG Anti-Gravity Treadmill is a medical device used for:

  • Aerobic Conditioning
  • Rehabilitation of the lower extremities
  • Treatment of neurological conditions
  • Weight reduction
  • General training to combat the diseases of aging

A pressure-controlled chamber gently lifts the user, allowing for unweighting to be achieved. Precise calibration allows for specific unweighting from 100-20 percent of the user's body weight in one percent increments . . . something no other unweighting modality can do!

AlterG's unique precision gives users the ability to set the precise point where exercise becomes pain free and provides clinicians an accurate way to measure progress. From professional athletes to senior citizens, the AlterG Anti-Gravity Treadmill offers accelerated athletic training and optimal recovery.


The AlterG's precise unweighting function allows patients to safely build their strength, endurance and conditioning prior to joint replacements and other elective surgeries.  A number of studies have shown how a prehabilitation program can help improve post-surgical functional outcomes.

Patient Recovery

The AlterG Anti-Gravity Treadmill provides customized partial weight-bearing following injury or surgery, which helps to restore a natural gait pattern and improve range of motion, coordination, timing and a host of other components of normal movement.  It provides controlled neuromuscular and proprioceptive input that enhances balance, confidence and ultimately independence.

Athletic Training Like Never Before

Some of the world's best athletes and sports teams consider the AlterG Anti-Gravity Treadmill an essential part of their athletic conditioning and rehabilitation programs. Use of the AlterG:
