An exercise apparatus has a body supporting carriage that moves relative to a frame in a direction having a vertical component. Levers are movably mounted on the carriage and connected to the frame in such a manner that movement of the levers relative to the carriage is linked to movement of the carriage relative to the frame.

Exercise method and apparatus

A full body reciprocating aerobic exercise machine that forces all of a user's limbs to move during the exercise. Because all the leg and arm levers move in unison, it allows a user to maintain the proper exercise motion even with an injured, incapacitated, or missing limb. The machine simulates uphill running or walking, and eliminates any joint impact to the user. The machine includes a central torso stabilization support, two leg levers, and two arm levers. The torso support and the leg and arm levers are mounted on a machine base. The leg and arm levers are rotatable through a limited but large arc relative to the torso support. The levers are synchronized so that the left leg lever must move with the right arm lever, and the right leg lever must move with the left arm lever, and so that all four levers move simultaneously. Because of this synchronization, the machine utilizes a 'cross-crawl' motion that is completely natural to any user. A user's learning time is therefore minimized.
