Adolescent obesity and diabetes is running amok worldwide. The causes of these conditions are not, as commonly believed, inactivity and too much dietary fat. And the cure for these, as well as for general robust health and improved athletic performance in kids, is strength training. Strong Kids, Healthy Kids is for parents, caregivers and for kids. I wrote the book to dispel and shatter the long lived myths that surround weight lifting and to, once and for all, free children from the grips of obesity and diabetes as well as to enhance every aspect of their health and athleticism.
