Abstract: The arm and leg-exercising machine is an apparatus that targets both the upper body and lower body to provide a full body workout. The upper and lower body workouts can be performed separately or simultaneously. The machine includes a generally U-shaped frame fixed to a base. Pedals and lateral handlebars are provided on the frame for respective leg (lower body) and arm (upper body) exercises. A three-drive mechanism including a plurality of pulleys or sprockets is coupled to the pedals and lateral handlebars and joined by bevel gears. A seat is mounted on the frame for strategically positioning an operator to employ the pedals and lateral handlebars.
