This book is an independent instructional guide. It is not affiliated with, endorsed by, sponsored by, or licensed by the National Football League, any league, conference, school, or club. Football is a contact sport and physical training carries a risk of injury. The drills and training guidance in this book are general information, not medical advice. Consult a qualified physician before beginning any training program, train under the supervision of a qualified coach, and stop immediately if you feel pain, dizziness, or any symptom of a head injury. Young athletes should do all strength training under adult supervision with an emphasis on technique over load. The author and publisher accept no liability for injury resulting from the use of this material.
It is a general instructional guide to playing technique, training and film study.
It is not medical advice. It is not physiotherapy. It is not a strength and conditioning prescription for any individual. It does not promise selection, playing time, or any outcome in the sport.
Report symptoms immediately, never hide them to stay on the field, and return to play only when a qualified medical professional has cleared you. Chapter 4 of the book covers this in full.
