It's hotter than HOT here in Arizona, and I am constantly reminding my clients to DRINK WATER! It is difficult to over-drink in the desert, and I can tell when some of them come in for a workout depleted. Sometimes, this heat is too much, so we may have to work hard to fight off that summer burn-out feeling. Some of the tips I've found helpful are: Stay inside during the hottest part of the day (11am-5pm), use an electrolyte replacement if your workout is longer than 60 minutes, get plenty of rest, eat smaller lighter meals with less animal protein and more fruits and vegetables, break your workout into 2 segments throughout the day to boost your metabolism and warrant off fatigue, try doing an aqua session instead of running or walking outside...I hope these tips help you feel better. I can guarantee they won't make you feel worse!
