The rowing machine has a main frame (20) with a sliding seat (38) and two foot support plates (32). The main frame has two side bars (29) and an adjustable magnet controlled wheel mechanism (50) between the bars. This has a magnetically conducting flywheel (51), a pulley (52), a spring cover (54), helical spring set (55) and a set of magnets (56). One end of the spring set projects past the underside of a guide pulley (28), fastened to a hollow frame girder (21), through the girder interior. It emerges at the upper girder end between two pressure wheels (25), and is fastened to a traction rod (64). The other end of the spring set is fastened in a slot (63) in the pulley.
