Body by Science: A Research Based Program for Strength Training, Body building, and Complete Fitness in 12 Minutes a Week by Doug McGuff, John R. Little

Body by Science: A Research Based Program for Strength Training, Body building, and Complete Fitness in 12 Minutes a Week by Doug McGuff is a revolutionary book for people of all ages who are interested in increasing their strength, improving overall fitness, and building muscle without spending hours at the gym. The book provides readers with an easy to follow, scientifically-tested program that McGuff has coined "High Intensity Training" (HIT).

Doug McGuff, MD, is the author of Body by Science and the originator of High Intensity Training. He has a medical degree, is a Board Certified Emergency Medicine Physician, and has worked as a personal trainer. McGuff's background allows him to bring a unique perspective to physical fitness, combining medical science and his training experience to create an effective exercise program.

At the heart of McGuff's program is the concept of "time under tension." To maximize the efficiency of exercise, McGuff suggests limited rest periods, longer exercise sections, and heavier weights. In short, HIT reduces exercise time by focusing on longer periods of tension rather than repetition. Also, the program can easily adapt to any fitness level, allowing for beginners and advanced exercisers alike to follow the same regimen.

The main results of this program can include improved muscle growth, greater strength gains, better posture, and improved aerobic fitness. All of these are accomplished through an efficient twelve-minute once-per-week workout. McGuff also outlines the benefits of HIT, such as improving insulin sensitivity, aiding digestion, and reducing stress.

For those seeking to build muscle and maximize their fitness, Body by Science provides a research-based program that can be achieved with minimal time investment. McGuff carefully outlines each step of the program and encourages the reader to track their progress and adjust the program as needed. Additionally, McGuff discusses the risks associated with HIT and emphasizes the importance of proper form and rest periods.

Ultimately, Body by Science is an excellent guide that can show readers how they can optimize their fitness levels in a fraction of the time normally associated with exercising. McGuff's research-based program is a great resource for anyone who wants to increase their muscle mass, strength, and overall fitness.
