On the 84th episode of The Richard Robbins Show, I sit down with a man who has dedicated his life to working with some of the highest-performing individuals on the planet. His clients include Olympic and World champions, and organizations ranging from General Electric to Deloitte, KPMG, BMW, Audi, and the Royal Bank of Canada.

Author of 4 best-selling books, CEO and Founder of Wells Performance, Dr. Greg Wells, has made health and peak performance his personal and professional obsession.

Dr. Wells has a Ph.D. in Physiology and serves as a Senior Scientist at the Hospital for Sick Children in Toronto. As a scientist and physiologist, he is focused on making the science of human limits understandable and actionable.

Though he has worked with Olympic athletes, Dr. Wells tells me that he wants to use his experience to help the general public live happier and healthier lives. "What I'm fascinated about at this stage in my life, is learning from those extremes. Learning from sports, learning from medicine to inform all of us mere mortals…I'm now trying to pull in all this information to help everybody that I can and have a bigger impact at this stage."

Dr. Wells tells me that understanding the thresholds between peak performance and exhaustion is a fine line.
