AlterG Anti-Gravity G-Trainer Treadmill is the only piece un-weighting rehabilitation equipment built on patented anti-gravity technologies developed by NASA. Patients begin therapy sooner and athletes can train through injuries.

G-Trainer Anti-Gravity Treadmills are changing the weight of the world. G-Trainers enable people to improve mobility and health, recover from injury and surgery more effectively, overcome medical challenges that limit movement, and enhance physical performance. Whether you're an elite athlete who can't afford bench time or an individual whose daily life doesn't have time for sitting still, G-Trainers are designed for everyone.

G-Trainer Applications


Physical activity has a direct impact on the state of your health, but physical activity can be restricted by medical conditions that limit mobility. The G-Trainer allows individuals to improve overall health, benefit from exercise regardless of many conditions that limit mobility and weight-bearing activities, and rehabilitate more effectively, with less pain after lower extremity injury or surgery.

Injury Prevention

Whether you're a world-class athlete or a weekend golfer, it's always preferable to prevent injuries rather than recover from them. The G-Trainer allows individuals to receive the health benefits of walking or running while reducing the risk of injury and they can get a great cardiovascular workout without the chronic pain so many people experience while exercising. And it allows athletes to increase training volume and speed while minimizing the risk of impact-related injury and continue training regimens without pain caused by chronic injury issues.
