Gain: The Life-Changing Science of Building Muscle

by Layne Norton

From renowned nutritional scientist and champion powerlifter, Dr. Lanye Norton, a revolutionary new look at how building muscle is our body’s most powerful tool for improving quality of life, extending longevity, and safeguarding against disease

For far too long, muscle mass has been viewed as a side effect of exercise rather than a cornerstone of lifelong health. In Gain, pioneering nutritional scientist and two-time world champion powerlifter Dr. Layne Norton reframes muscle as a vital organ in its own right, as deserving of attention as the heart or brain. Drawing on the latest research, Dr. Norton reveals that muscle does far more for us than a toned appearance or the ability to set a new personal best; it can help us live pain-free, improve cognition, increase energy, help us get fit, and prevent disease.

Building muscle may seem reserved for gym rats and vanity seekers, but in Gain, Dr. Norton presents a compelling argument that both men and women of all ages and backgrounds can benefit from his program developed from over two decades of his nutrition research, work with thousands of clients, and his own competition-level training. With easy-to-understand guidance, Dr. Norton breaks down exactly how to go about building muscle without having to become a powerlifter, as well as exactly what types of foods and supplements are nature's secret weapons for building the muscles that fuel longevity and a healthy body.

Whether you’re in the gym every day or haven’t touched a dumbbell in years, Gain is an accessible blueprint for building and maintaining strength at any age.
