Coming off one of the most popular episodes in 2014 “Cardio is for Suckers” we bring in the World’s #1 expert in High Intensity Interval Training! Dr. Mark Smith has researched the effects of HIIT for the past few decades and has some amazing data and insight into why this type of training is so effective! Doc Smith is an extremely active member of the TPI Fitness Advisory Board and a great friend of mine. Doc is also a noted expert on nutrition and the prevention of diseases through food and lectures and writes on the benefits of the Paleo Diet.
