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

Rehabilitation

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.

Training and Conditioning

Elite athletes and weekend joggers alike are always looking for technological advancements to help them run farther, faster. The G-Trainer is being adopted by athletic trainers, conditioning specialists, and exercise facilities to augment training and conditioning routines, enhance performance, and provide the most advanced option in reduced-impact exercise.

The G-Trainer Difference

Unrestricted Mobility

You can reduce their body weight easily without restriction. A person is able to maintain a normal gait, stride length, bounding, leg kick, and normal body positioning.

Natural Body Movement

Overcome limitations such as water resistance and cumbersome harnesses associated with conventional unweighting systems allowing for a natural gait pattern. The G-Trainer's supportive force is at your core and is uniformly distributed over the your lower body making it very comfortable while allowing for natural body movement.

Full Range of Motion

You can walk or run with a full range of motion. Not only do you have a full stride length but your upper body is not restricted in movement. Other systems that support a person's weight make it nearly impossible to achieve a full range of motion. Because the G-Trainer allows the you to reduce your body weight you're able to even extend range of motion to condition muscles more thoroughly.

Extended Variable Options

With the G-Trainer you can add reduction of body weight to traditional treadmill variables of speed and incline. Variables can be adjusted and programmed to meet any health, medical, therapeutic, training, or conditioning need. The G-Trainer continually adjusts to ensure the accuracy of set variables is consistent throughout a session.

Broad Variable Range

Weight, speed, and incline settings can be set with precision and include a broad range. Effective body weight can be reduced to as low as 20% of the your body weight with reduction increments of 1% allowing for progressive weight bearing. Speed variables can be adjusted up to 18 miles per hour in forward motion or 10 miles per hour in reverse and incline can be set up to 15%.

In-use Setting Adjustment

Each variable can be adjusted to different levels while in use. This advantage means you can adjust settings to meet your performance level and tailor workouts to account for ability level, pain or fatigue. Variables can be altered on-the-fly your or your clinician without interrupting your workout.

"We use the G-Trainer for rehab, extra cardio work without the pounding, and speed training. For post surgery and injury rehab, like knee scopes and ankle issues, we've been able to put players on the G-Trainer early and not only work them back into contact but to look at their mechanics and see that they are running properly."

"By reducing my athletes' effective body weight using the G-Trainer, they've increased their training volume as high as 25%, without increased risk of injury. This has enabled our runners to compete at their highest levels ever."

Alberto Salazar,
Director of Nike's Oregon Project

"Without the G-trainer I would not have been able to qualify for the Olympic Marathon team or win the USA cross country championships. I have trained right through a couple of season-ending injuries and come back even stronger than before."
