Abstract

A synchronous/asynchronous exercise machine is changeable between a synchronous exercise mode wherein a user's limbs, such as his legs, oppositely reciprocate, and an asynchronous exercise mode wherein the user's limbs move independently. The synchronous/asynchronous exercise machine may comprise a first movable element for accepting a user's limb, and a second movable element for accepting another limb. A load source against which the user can exercise may also be provided. A first drive belt operatively connects the first movable element to the load source, and a second drive belt operatively connects the second movable element to the load source. A quick change mechanism, which may be connected to the first movable element, is releasably engagable with the second drive belt for changing the synchronous/asynchronous exercise machine between the synchronous exercise mode and the asynchronous exercise mode.
