The New Science of Strong, the new special edition from the editors of Shape, is an all-inclusive guide to the importance of strength training for a fit and healthy lifestyle at any age. Drawing on the research and expertise of scientists, sports physicians and nationally-recognized physical trainers, The New Science of Strong focuses on and delivers guidance into High Intensity Interval Training (HIIT), the strength-building and weight-control technique that offers transformative results in far less time than gained with conventional workouts. Separate articles and sections delve into the mechanics of building lean muscle, strategies for healthy weight loss, working out with (and without) a trainer, and the critical roles played by mood, your metabolism, the body’s hormones, and nutrients such as proteins, carbohydrates and vitamins. The New Science of Strong also includes three scientifically-tested workouts, with detailed instructions as well as a primer on muscle and fat. Plus: We also provide you with our guide to the key equipment you’ll need for better training and “Words to Lift By”—quotations that will motivate you.
