Before you go too far... you should try it first... I did... and hated it... if you want to know what it feels like... just sit on the floor and use a broom to do the rowing... yuk...
Hate to be a party pooper... but that was "my" experience... I must admit that I do know some people who just love it... especially those who do it in the rapids...
Best of luck to you... and, let us know how it turns out...
