A fitness machine is provided, which includes a base frame having a pair of vertical side members; a track assembly rotatably mounted to the base frame between the vertical side members; a drive assembly for rotating the track assembly relative to the base frame; a bench rest assembly slidably mounted to the track assembly for supporting a user in a supine position; a handle assembly and a footrest assembly fixedly attached to the track assembly; and a control system for directing the drive assembly to alter the angular orientation of the bench rest assembly to vary the resistance experienced by a user during an exercise routine. The operation may be manual, programmable, or adaptive to the user's performance, based on repetition time and/or heart rate.
