Check out the interview I did with Dr Doug McGuff. Doug lives in South Carolina and is the co-author of Body by Science, owner of Ultimate Exercise gym, and, and a full-time ER Room Physician. Doug is one of the world’s leading experts in High Intensity Strength Training and works tirelessly to help people to improve their health and realise the benefits of this highly effective but widely misunderstood training method.

In summary, we cover the origins of HIT, strength training fundamentals, benefits, techniques, and strategies, nutrition (Paleo Diet), stress management, Doug’s involvement with the “4 Hour Body” (written by Tim Ferriss), the impact of programs like “Insanity” and “P90x”, the development of the HIT movement, sport specific training, and even how to effectively prepare for “fun runs” like “Tough Mudder” and “Survival of the Fittest”. For those that are familiar with Doug and his work, in this interview, you will learn more about Doug as a person, his experiences, and his personal mission.
