This is a really good idea. I got a yoga DVD and used it last spring to get back in shape for riding because I don't ride a lot in the winter. The difference was noticable. I've started it already this spring. Also, I've added walking lunges, squats, crunches, and wall-push ups. Hopefully this way I can minimize the spring time painfulness!
