I started rowing last summer after visiting a friend in Madison, Wisconsin who had a Concept2. I loved it and since then have been rowing approx. 40–70k a week. I appreciate that lack of wear and tear on your body and have recommended it to friends in Atlanta and Kalamazoo, Michigan, each of whom bought one. I have lost 10 pounds in a year (and can eat anything that I want). It is a great workout. Wish I had started sooner.
