Abstract: This invention offers a rowing machine's mechanical resistance device which comprises an electric motor or a solenoid, a programmable control means and a custom algorithm, controlling the programmable controls means. It eliminates the compromising effect of backlash between the rower's handle and the resistance imparting device. This backlash is present between the power and the idle phases of rowing strokes on all state of the art rowing machines comprising flywheels. Ultimately, this invention allows all rowers to improve their rowing form and avoid injury.

Abstract: This invention offers a rowing machines' mechanical resistance device which comprises an electric motor and a programmable control. While it simulates the beneficial responses of a mechanical resistance imparting device comprising a fluid pump and a flywheel, it simultaneously eliminates the compromising effect of backlash. Said backlash exists on commonly used, state of the art rowing machines between the idling and the pulling phases of a rowing stroke. By eliminating backlash, this invention allows rowers to achieve better rowing form and avoid injury.
