Astronautsdo not have these types of functional activities in space and must replace them with treadmill exercise using a loading harness to hold the astronaut in place on the treadmill. However, the treadmill loading harness is uncomfortable and prevents astronauts from exercising normally and with the same intensity as on Earth. Whalen suggested using air pressure as an effective way of applying a high force, equal to body weight, to astronauts during treadmill exercise to replace the harness system.

According to Barfod, another market for the G-Trainer is professional athletic teams and athletic departments at universities, which use the G-Trainer to help athletes recover from stress injuries. Many teams in the National Basketball Association (NBA), the National Football League (NFL), and the National Collegiate Athletic Association (NCAA) have G-Trainers.

Whatever the cause of an injury, rehabilitation can be painful, and patients often alter their gait, stride length, or body position to over-compensate for the pain. The G-Trainer reduces the effect of gravity and weight, which makes it more comfortable for a patient to focus on a normal, correct gait instead of worrying about more injury and pain. This allows patients to develop good habits and condition their muscles while their bodies are still healing. The G-Trainer is comfortable like water training, but offers more realistic support of the lower limbs in their free-swing phase, allowing the legs to swing more normally than they would in water. Precision is another advantage the G-Trainer offers over water rehabilitation.

The comfort of the G-Trainer is an improvement over harness systems, Barfod explains, because the support remains constant, even when the system is supporting a high percentage of weight or a patient weighing several hundred pounds. Conversely, harness systems chafe and can become uncomfortable quickly, especially if a patient is obese or needs a larger percentage of weight lifted. In a harness system, there is typically no reliable, precise method to change or record the amount of weight on a weak or injured limb and no digital readout to keep patient and trainer informed.
