Walking my dog twice a day (no getting out of that!), turning my compost pile once a week, riding my bike to the post office and back every day (because I work from home, that's my commute), and yoga and Pilates keeps me active in the winter. My riding is limited to 1-2 longer rides per week on the weekends. I do not have a mountain bike, but if I did, I would ride in the woods.
