You've been working toward your goal for months now, and it was all going so well. Your energy was great, you felt strong and in control. Then out of nowhere, you hit a wall. Suddenly, all your workout-related joy is gone, and your whole body feels heavy. Chances are, you've been overtraining.
Overtraining puts our bodies into a sympathetic state (fight or flight) that releases cortisol, a stress hormone involved in cravings, weight gain, and adrenaline in the body. Overtraining is a common problem in weight training, runners, athletes, and even yogis. It occurs when the volume and intensity of exercise exceeds an individual's recovery capacity. People who have trained too hard cease making progress and can even begin to lose strength and fitness. Long story short, it's not ideal.
