We hereby make use of an energy harvester system that moves in response to movement of the motion of an forearms exercise machine for converting kinetic energy of the forearms exercise equipment into electrical power. Our system makes use of the gripping rod connected to spring based motorized mechanism having rack pinion arrangement and multiple motors to power the system and generate power. The system aims to provide resistance to forearms movement while generating power from the same thus serving dual purpose. The machine makes use of 3 motor arrangement to provide 3 levels of generation capability. The machine aims to generate electricity through horizontal motion created while working our forearms. The spring based mechanism allows for efficient resistance settings in the machine as needed. Increased resistance leads to increased power generation in the machine.
