One could say that Dr. Doug McGuff is one of the pioneers of BMX motocross bike racing in Texas. He built the state’s first race track, having gotten hooked on the sport as a teenager in the 1970s. The sport also triggered a deeper interest in fitness. As McGuff tried strengthen his core for bike racing, he discovered Arthur Jones’ Nautilus training technique and bartered janitorial services for a Nautilus gym membership. McGuff’s interest and aptitude for studying the body led him to pursue medicine at the University of Texas in San Antonio. He specialized in emergency medicine, was chief resident of emergency medicine at the University of Arkansas in Little Rock, and a staff physician at Wright-Patterson Air Force Base Hospital in Ohio. McGuff is currently an ER physician with Blue Ridge Emergency Physicians in Seneca, South Carolina. The other side of McGuff’s career is dedicated to fitness, or as he says—helping people never have to go to the ER. Realizing a lifetime dream, he opened up his own fitness facility in 1997 called Ultimate Exercise. The gym is dedicated to the type of high-intensity fitness training using the Super Slow protocol. In this episode of STEM-Talk, McGuff talks about why this type of exercise is better for the body, safer, and able to prevent age-related conditions such as sarcopenia. McGuff is the author of three books: “Body by Science: A Research-Based Program for Strength Training, Body-building and Complete Fitness in 12 Minutes a Week,” http://amzn.to/2fy7vKN (co-authored with John Little), “The Primal Prescription: Surviving the “Sick Care” Sinkhole,” http://amzn.to/2fLTBtl (co-authored with economist Robert Murphy), and “BMX Training: A Scientific Approach.” http://amzn.to/2fUhqPd
