An exercise machine suitable for exercising a person's muscles contains a frame (100Y), a seat (102) situated over the frame, a seatback (104 or 104Y), a connection mechanism (106 or 106Y) for flexibly and adjustably connecting the seatback to the frame or/and the seat, and a pedaling mechanism (112Y) connectable to the frame and having a pair of movable foot pedals (140). The seatback is capable of swiveling and can be segmented to facilitate swiveling. The machine typically has a pair of retractable frame legs (302) so that the machine can be used for stationary cycling when the legs are retracted and as an elevated exercise bench when the legs extend downward. The machine may include a mechanism for rapidly switching the seatback between inclined and flat positions. |
