Twelve minutes is all it takes to maximize muscle size and strength, shed fat, and dramatically reduce your risk of heart attack, cancer, and diabetes

Body by Science challenges everything you thought you knew about exercise and takes you deep inside your body’s inner workings–all the way down to the single cell–to explain what science now knows about the role of exercise in human health. With the help of medical diagrams and step-by-step photos, exercise scientist Doug McGuff, M.D., and weight-training pioneer John Little present a revolutionary new workout protocol that fully leverages the positive effects of high-intensity, low-frequency weight training, while avoiding the negative effects of traditional aerobic-centric exercise.

In as little as 12 minutes a week, you’ll:

• Build muscle size and strength, fast
• Optimize cardiovascular health
• Ramp up your metabolism
• Lower cholesterol
• Increase insulin sensitivity
• Improve flexibility
• Manage arthritis and chronic back pain
• Build bone density
• Reduce your risk for diabetes, cancer, heart attack, and more
