GYMWATCH has developed a patented sensor to measure strength and motion across fitness exercises, including machines, free weights and bodyweight. The sensor records the full range of motion of an exercise, determines every strength component, all repetitions and detects incorrect exercise execution to help ensure exercises are performed properly and desired fitness goals are reached. The GYMWATCH Sensor tracks every strength component, like starting strength, explosive strength or speed strength, as well as the precise motion amplitude in every exercise. It can differentiate between full and partial repetitions and the time under tension of eccentric, concentric and static muscle contractions.
