Exercising in the Heat

I have received a few questions about this over the last couple of days and thought it was important to give advice on exercising in the heat!
I suggest that you try to workout in the morning or late evening during the hot summer months. I can speak from personal experience about how heat affects you during workouts. Your heart rate can be elevated by 5 to 15 beats versus exercising in normal temperatures. You also sweat a lot more and can cramp up easily as you also lose more sodium due to the high sweat levels. You will also see that it is more difficult to hit target heart rates or target perceived exertion levels in the heat as you can feel exhausted and drained.
I suggest that you avoid exercising outside in temperatures above 90 degrees (maybe even 85 degrees). Your health is too important to risk by trying to fit in a hard interval workout on a very hot day. Of course, your doctor is the best source of information on what is too hot a temperature for your workouts.
One last point, regardless of whether you are working out in the heat or on a 70 degree day, you should always have a water bottle with you and keep hydrated during your workout. If you feel thirsty while working out, then you are too late as you are already dehydrated. Being proactive about this will keep you safe and performing well.
The #1 thing to focus on while trying to fit in your summer outside workouts is to be safe. So do some smart planning, avoid making excuses and get your workouts done early in the morning or late in the evening if you absolutely can’t do the mornings.
When it’s just too HOT outside, hit the GYM!
GOOD LUCK AND HAVE FUN!
IMPORTANT NOTE: IF YOU EVER FEEL SICK OR THE SLIGHTEST BIT DIZZY WHILE WORKOUT (IN THE HEAT OR OTHERWISE), STOP WORKING OUT IMMEDIATELY. YOU ARE PROBABLY DEHYDRATED, LOW ON CALORIES AND/OR PUSHED TOO HARD. IF YOU TAKE IN SOME FLUIDS AND FOOD AND DON’T FEEL BETTER, I SUGGEST YOU CALL YOUR DOCTOR RIGHT AWAY. REMEMBER, BEING SAFE IS THE #1 PRIORITY ON YOUR FITNESS AND/OR WEIGHT LOSS JOURNEY.
Stay Cool!
