NASA Treadmill Makes Exercise Easy

Alter-G G-Trainer

The G-Trainer is a new invention that makes exercising easy for everyone. Forbes reports "Alter-G G-Trainer's unique treadmill system allows people to train and recover by reducing their effective body weight via positive air pressure. Because the technology, developed by NASA, controls the impact on the body, people who have trouble standing, walking or running can do so comfortably. Athletes also can get a workout minus the stress on their joints."

Implications - The G-Trainer is able to reduce your body weight from "three to 80 percent, in one percent increments." The machine uses air pressure to create a sort of "uniform, upward-lifting force on the lower body." The featured images show a man running on the treadmill with a tube in his mouth that connects to different spots on the machine.
