In our forthcoming book (The Body By Science Question & Answer Book), Dr. McGuff and I devote a significant section to training and rehabilitating the lower back. As the lower back can prove problematic to some (by some estimates, between 75 and 85% of the population will experience lower back pain at some point in their lives), keeping it strong is very important and can go a long way toward keeping you in the 15 to 25% that do not experience such problems).

Dr. McGuff has put together a two-part video that will help trainees immensely in strengthening this important area of the body. In Part One, Dr. McGuff describes the anatomy of the lower back and what muscle groups we need to focus on with our training. In Part Two, he continues with his presentation, demonstrating three exercises that can be performed to strengthen the lower back for those who do not have access to MedX or Nautilus lower back machines.
