to be able to provide a little motivation!
Now if only your example of rowing could get me to give that another try. Just don't have the time and inclination to drive to the gym though.
It helps that my rower is in the next room. Alas, can't use it right now because of intractable back spasms. They are dragging on way too long. I have a doc appointment Wednesday, although not at all sure that will turn out to be much help.
