The present invention relates to a magnet-controlled rowing exercisor which utilizes an adjustable magnet-controlled wheel mechanism such that the user can adjust resistance in exercise. A magnet controlled wheel mechanism includes a magnet conductive fly wheel and cooperating magnet set for providing variably adjustable resistance. The mechanism further includes a coaxially mounted leading wheel for securing an end of the pulling string in a spiral configuration and a spiral spring for exerting a counter-rotational force on the leading wheel. In use rotation of the leading wheel caused by extending the string creates tension in the spiral spring sufficient to retract the string for repeated motion. The magnetic resistance has the advantage of being less subject to fatigue than common known devices, quieter that prior art devices and more easily adjustable in resistance.
