When it's cold outside, it's tempting to just throw on a heavy sweatshirt and sweatpants and hit the ground running. Problem is, this could leave us standing running out in the cold, wet and uncomfortable.

To keep warm think about correcting these common mistakes many people make while working out in the cold:

• Mistake #1: Wearing jeans or street clothes. Unless they’re waterproof (which most jeans are not) and designed to dry quickly (again, not my jeans), you’ll end up freezing cold and miserable.

• Mistake #2: Wearing only cotton. Cotton is great, but not for working out in the cold weather since it absorbs and retains sweat, rain, and snow.
• Mistake #3: Not layering clothing. Perfecting the art of layering is key to exercising happily outdoors in the winter. Not sure how to do it, be sure to check out my how to on layering effectively.
• Mistake #4: Layering socks. I learned this lesson while skiing and as a kid and the theory is that your feet will stay warmer with more layers, however, you could end up cutting off your circulation in your tootsies and making things much worse (and painful). Instead, invest in one good warm pair of wicking socks.
• Mistake #5: Not wearing a hat or gloves. We all lose a good amount of heat through our heads and hands, so keep warm by covering yours up.
