45. Take It to the Tradmill
When the weather's raunchy or you just don't feel like getting out and walking, power walking, or running around the park or the track, you can always work out on the treadmill. It's an easy way to get your workout in no matter what, and you can work your way up from slower speeds. Remember, any exercise is better than none! However, once more, when you're on the treadmill, make sure that you're working hard enough to get your heart rate up for maximum potential. Like with the Elliptical, try to stay on at various speeds for at least half an hour.
