Abstract: The belt drive assembly includes a frame having a first plate including an inner surface, an outer surface, a first end, and a second end, a second plate including an inner surface, an outer surface, a first end, and a second end, and a shaft disposed between the first plate and the second plate. The belt drive assembly also includes a first pair of idler pulley wheels positioned coaxially at one end of the first plate, a second pair of idler pulley wheels positioned coaxially at one end of the second plate, a drive pulley wheel rotatably mounted onto the outer surface of the first plate, a driven pulley wheel rotatably mounted onto the outer surface of the second plate, and an endless belt trained on the drive pulley wheel, on each idler pulley wheel, and on the driven pulley wheel.

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.
