If you walk or run regularly as your form of cardio, it's important to exercise on all types of surfaces. Doing so offers varying degrees of shock absorption for your joints and feet, so mixing your exercise terrain strengthens the muscles around your hips, knees, and ankles in different ways. Instead of sticking to the treadmill all the time, try to alternate your workouts between pavement, grass, dirt trails, sand, track, and your beloved treadmill.

Even though the
Chicago Marathon was marred by scorching temperatures, I am still thinking about layering for cooler weather. You want extra layers that will keep you warm without adding unnecessary bulk to your frame.

Let me know what you think.

When the weather is bad, or you don't feel safe running or walking outside,
treadmills are great. The only thing that's bad is that you are doing the same repetition of motions over and over again. You use all the same muscles, which is very unlike moving on actual terrain outdoors (and very boring too).
