BIMGEC emulates weight in zero gravity, both for weight training exercises and as a rowing machine for aerobic workouts. In weight training mode it can deliver from as little as 12kg to over 180kg of concentric resistive force with infinite resolution between these settings. It also incorporates a unique eccentric bias system to increase the effective load during the eccentric phase of a rep up to 360kg. The mechanism is totally powered by the aerobic workout, requiring no external energy supply. The entire system weighs 9kg and is roughly the size of a shoebox.
BIMGEC was designed for an open competition by NASA for a Bio-Inspired Advanced Exercise Concept for use in their Orion capsule for future manned interplanetary missions, which it won.
