About the episode:

In today’s episode, I chat with Dr. Kirk Parsley about the importance of sleep, stress, and how they play a massive role in your ability to perform, lose fat, and gain muscle.

Dr. Parsley is a traditionally trained western medical doctor who has discovered that his medical training did not provide him with the necessary information and expertise to help improve and maintain his patient’s health.

After discovering that he had been trained to recognize and treat disease, he set out on a mission to learn everything possible about actually optimizing health.

He now works with clients and organizations on four pillars of health; sleep, nutrition, exercise, and stress control.
