My opinion is that the young, or new rower can benefit from a general weightroom based strength training program of the type outline above. However, the already well trained rower probably has little to gain from further increases in "weightroom strength". Movement specificity is critical. The strength training I have outlined really has it's greatest application in either very short events such as the 500 meter dash, or to the brief acceleration phase at the start of a traditional 2k race. I think it is also very useful when it allows technical elements to be emphasized in isolation. But, remember, there is no correlation between short sprint performance (strength) and 2k performance on the ergometer in a group of similar sized elite guys or women. So weight train, but remember that the best training for rowing is still rowing!
