An exercise machine that enables a user to perform a variety of repetitive exercises in reclined, sitting and standing positions. The machine permits a user to perform exercises not possible on a traditional Pilates Reformer machine. The machine includes a frame with parallel side rails formed of extrusions, with a carriage that is mounted for rolling movement along the frame. A plurality of tension springs are selectively detachable/attachable to the end of the frame, to allow the user to decrease/increase the tension on the carriage. Angularly adjustable crossbars are mounted at both the head and foot ends of the frame, as are stationary platforms for the user's feet and/or hands; in addition, a raised transverse bar is mounted at the head end of the rolling platform. The combination of platforms and bars enables the user to perform a variety of exercises in standing positions. The frame includes legs that raise the side rails above the floor. A barbell rack and storage tray are mounted between the rails so as to be positioned generally beneath the frame, and are accessible vertically through the open space between the rails when the rolling platform is retracted by the springs to the foot end of the assembly.
