An exercise machine suitable for exercising a person's muscles contains a frame (100Y), a seat (102) situated over the frame, a seatback (104), a connection mechanism (106Y) for flexibly and adjustably connecting the seatback to the frame or/and the seat, and a pedaling mechanism (112Y) connectable

An exercise machine suitable for exercising a person's muscles contains a frame (100Y), a seat (102) situated over the frame, a seatback (104), a connection mechanism (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 connection mechanism includes (a) a seatback-attaching portion (120, 180, 184, 186, 188, and 190) attached to the seatback and (b) a support rod (128Y) extending between the seatback-attaching portion and a location within the frame. The support rod is of adjustable length for adjusting the incline of the seatback to the seat. The seatback can swivel about a swivel axis of the connection mechanism. The exercise machine normally has a pair of frame legs (302).
