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.
