I've always loved the quote by Kenichi Ohmae;
"Rowing harder doesn't help if the boat is headed in the wrong direction."
If you haven't identified your end goal properly, you’ll row and row and then find yourself in the wrong place. Which ultimately destroys the motivation of those engaged in badly planned methods of overtraining certain areas of their body.
Just because you've started rowing, it doesn't mean you can't reassess the journey and turn your boat around. The sooner you plan where you want to be, and how you'll reach that place, the easier your journey will be. The idea of engaging in a properly designed and prescribed exercise program is to work smarter, not just harder and longer.
