I have been browsing a few things with a view to updating my blog links, along the way I found :-
Men's fitness UK
Pete Reed's rowing form guide
The British Olympic rowers guide to using an ergo effectively. The article is a bit brief, but very useful if you have only ever abused the rowing machine in your local gym rather than 'rowed' it ;o)
Great website to follow all of international rowing, from Juniors through Senior to Masters level. Coverage of the Semi's and Final's (including live streaming) of the World Rowing Championships in Poznan, Poland starts tomorrow.
The website includes events, results, and athlete biographies (including MEET THE ATHLETES - Video Interviews)
