It's so tempting when the mercury drops to stay inside where it's warm and toasty. While cuddling up on the couch will keep you warm, it won't do anything for your fitness level.

Plan on keeping up your outdoor routine for as long as you can, and get ready for a winter outdoor workout by stocking up on the proper gear to keep yourself warm. If you can stay warm while you're exercising outside, you're more likely to stick to it.

If exercising in the cold air just isn't possible, find yourself an indoor workout ... pronto.
