Expect to Sweat

As your workouts get longer and harder, you use more muscle and generate more heat. Blood flow to the skin allows your body to sweat and thereby, cool you through the sweat’s evaporation. Short bouts of exercise don’t typically produce a lot of heat, but longer bouts, particularly that of high intensity aerobic work, can. Monitor your pre-, mid- and post-workout hydration so that you can always make enough sweat to cool your body!
