Abstract
Resistance in a rowing exerciser may be adjusted by varying the distance between a magnet set and a magnetically conductive flywheel that is attached to a second wheel having a cord wound there around and connected to a handle which is pulled by a user. A spiral spring engaged with the second wheel causes retraction of the cord after it is extended by the pulling action.
