1. An exercise system comprising:
a housing having an upper cover, an open bottom, front and rear faces, and left and right side faces, the rear and side faces each having a top edge and a bottom edge and a first height between the top and bottom edges, the front face having a top edge and a second bottom edge and a second height between the top and edge and the second bottom edge greater than the first height; a left foot pedal and a right foot pedal, laterally spaced parallel guiding slots formed in the upper cover, a pedal mount extending through each guiding slot and attached to an associated foot pedal, each pedal mount having a lower extent; a glide rail beneath an associated guiding slot, each glide rail having an upwardly facing recess slidably receiving an associated lower extent; a motion imparter including corner pulleys, a cable in a closed loop configuration trained around the corner pulleys and attached to the lower extents of the pedal mounts to move the foot pedals in equal and opposite directions during use; and a lower main plate removably coupled to the open bottom of the housing, an adjusting pulley coupled to the lower main plate adjacent to the front face receiving the cable, a tension adjuster including a tension dial with a threaded interior extending through the upper cover and rotatable with respect to the upper cover, a pin having a threaded upper end received within the threaded interior for axial movement of the pin in response to rotation of the tension dial, the pin having a lower end with an attached disk, a tension pad coupling the tension dial and the pin to the upper cover, two elastomeric friction disks between the tension pad and the attached disk with the adjusting pulley between the friction disks whereby rotation of the tension dial in opposite directions will vary the height of the adjusting pulley and thereby increase and decrease the pressure needed for reciprocating the foot pedals. |
