About Alter G

The G-Trainer anti-gravity treadmill is much more than an exercise machine. It enables individuals to reduce their effective body weight for health and medical applications, to reduce the risk of injury, and to expand athletic training and conditioning programs.

Professional athletes, top collegiate programs, and rehabilitation and training clinics across the US are experiencing the unique benefits of walking and running at reduced body weight.

Since the original prototypes were installed with partners and training facilities, individuals have been making claims on the benefits they receive. When adding the G-Trainer to general conditioning, cross training, and performance enhancement routines, individuals at health clubs to elite athletes report measurable increases to their fitness goals. Rehabilitation clinics and other medical facilities see faster recovery times and lower overall costs for patients. Clinicians are also prescribing the G-Trainer to improve mobility with neurological patients, increase exercise options for patients with weight control challenges, and improve overall health of older individuals.

Everyday we hear from physicians, healthcare specialists, athletic trainers, athletes, and other individuals about why and how they're using the G-Trainer.
