What are some standard/average rowing distances for 20:00 on a stationary rowing machine.I'm not talking about professionals.. just regular rowing in a fitness class.Thanks!!owers rarely exceed 34 strokes per minute (except in races and sprints), and do a lot of their training at about 18-28 strokes / minute. - The fan resistance settings change the intensity and distance-Each machine differs slightly.
