Have you had a chance to read McGills book, “Ultimate Back Fitness and Performance” ?
Dr. Stuart M. McGill is a professor of spine biomechanics at the University of Waterloo (Waterloo, ON, Canada). His advice is often sought by governments, corporations, legal experts and elite athletes and teams from around the world. Difficult back cases are regularly referred to him for consultation.
His work is the most up to date resource we have. The information presented in this book may well change your opinion on current “Core” training.
This book should be a mandatory textbook for all Strength and Conditioning coaches.
Rotational core work – with movement coming from the lumbar spine, such as windmills, side bends etc. only increases the risk of disc injury and and doesnt meet the needs of core training.
How does the idea of “the core exists to resist rotation , absorb and distribute force” sit with you ?
Much of the information on this site, in my opinion, is unfortunately dangerous and outdated.
