Winter workouts: Watch the wind chill

Updated: 01-15-2013

Wind chill extremes can make exercising outdoors unsafe even if you dress warmly. The wind can penetrate your clothes and remove the insulating layer of warm air that surrounds your body. Fast motion, such as skiing or skating, also creates wind chill because it increases air movement past your body. If the air temperature dips well below zero F (minus 18 C), choose an indoor activity instead.
