摘要： An exercise machine includes a longitudinal rail for slidably supporting a carriage assembly together with the weight of a user. The longitudinal rail is supported at an elevation above a support surface by a fore support structure positioned at the fore end of the rail and by an aft support structure positioned at the aft end of the rail. A carriage assembly slidably engages the rail structure and supports the weight of a user on the rail structure. The carriage assembly includes roller wheels for rolling engagement with the rail. A lever is pivotally connected to the rail and enables a user to operate the exercise machine. The lever has a hand grip assembly at one end and a foot grip assembly at the other end. A resistance structure is connected to and positioned between the fore end of the rail and the carriage assembly and provides resistance to translational movement of the carriage assembly and pivotal movement of the lever. A cable connects the lever to the carriage assembly and, thereby, to the resistance structure. A pulley is secured to the aft end of the rail and is used to guide the ends of the cable to the lever and to the carriage. A seat is positioned on the carriage for sitting by a user, who operates the exercise machine in a conventional or modified rowing-type fashion.
