An exercise machine carriage system which allows for a wide range of exercises while maintaining improved balance and control for the exerciser. The exercise machine generally includes a stationary frame and a carriage adapted to slide along at least one track on the frame. The carriage may include at least one opening on its upper surface to be used by an exerciser to perform a variety of exercises. The carriage may also include, either in combination with the openings or alternatively, at least one carriage strap extending across its upper surface for use in a variety of exercises. Platforms may also be included on either end of the frame, each of the platforms including its own platform strap. By utilizing such openings and/or straps, a wide variety of exercises may be accomplished that otherwise would be difficult or impossible to perform on conventional exercise machines.
