An exercise device (100) comprises a frame (120) and a resistance component (130) coupled to the frame (1 20). The exercise device (1 00) further comprises a cable (140) coupled to the resistance component (130) and supported by the frame (120), configured to transmit a force from a motion end (142) of the cable (140) to the resistance component (130). The exercise device (100) also comprises a pulley system (150) movably coupled to the frame (120) along a track (124), the pulley system (150) supporting the cable (140) as the cable (140) transmits the force to the resistance component (130), the pulley system (150) configured to be reversibly fixed in position relative to the frame (120). The pulley system (150) includes a first pulley member (152) and a second pulley member (156), the second pulley member (156) being removably attachable to the first pulley member (152) such that at least one of the first pulley member (152) and second pulley members (156) can be independently moved along the track (124). |
