When summer is just around the corner, your workouts need to adjust to the warmer weather. If you exercise outdoors -- or at an indoor facility with no air conditioning -- you need to take the threat of heat injury seriously.

As the weather turns hot, it will take your body close to 2 weeks to adjust to exercising in the heat. During this period, lower your exercise intensity level.

By allowing this gradual transition, you'll reap the benefits of a lower core body temperature, decreased heart rate during exercise, and a lower risk for dehydration and electrolyte depletion.
