Rowing

A rowing technology comprising:

• a rowing machine having
• a seat slidably mounted on a longitudinal rail,
• a conductive disk held for rotation on a bearing,
• an electromagnet to generate a magnetic field passing through the conductive disk,
• an electronic controller to control a magnitude of the magnetic field,
• a one-way clutch driven by a rowing handle to cause rotation of the conductive disk,
• an extended flexible element connected between the rowing handle and the one-way clutch, and
• a return mechanism coupled to retract the extended flexible element and the handle,
• the electromagnet and conductive disk providing a controllable resistance through the extended flexible element and the rowing handle to a rower of the rowing machine in each rowing stroke of a series of rowing strokes of the rower,
• a user interface for a user selection of a stored resistance profile to be effected by the electronic controller during the series of rowing strokes of the rower, the stored resistance profile specifying a fixed or varying resistance that a rower experiences over time during the series of rowing strokes,
• the electronic controller being configured to cause the resistance of the electromagnetic brake to vary during the series of rowing strokes to match the selected stored resistance profile, and
• a display to visually present a rowing figure performing rowing strokes matching the selected stored resistance profile.
