I try to do something when I get up each morning, whether that's a vigorous yoga practice, a three-mile walk to the coffee shop (no doughnuts!), or a Firm work-out. When the weather is nice and warm, I'll then try to supplement that (especially on days I can't quite manage to do the morning work) with a noon-time walk or an evening walk. I also rely on scheduled classes, typically one or two days per week, either in body conditioning, or power yoga. Finally, during the summer, I try to bicycle the 20 miles, roundtrip, to and from work every day I can.
