Dr Phil Maffetone, the man who wrote the training prescriptive that changed how endurance athletes approach sport, joins Jon and Debbie on today's episode of Fit Fat Fast for a lengthy discussion on health and well-being.

Debbie and Jon discuss with Dr. Maffetone the entirety of his approach to health and fitness, of which heart rate is only but a small part. They talk about diet, training, sleep, recovery, muscle imbalance and the importance of proper brain function. Enjoy!
