Proper dynamic stretching and warm-up prior workout, as well as static stretching after workout, reduce the risk of injury, increase muscle strength, improve overall performance, and enhance joint flexibility and range of motion. I am a bodybuilder, and Mark Kovacs "Dynamic Streching" immediately grabbed my attention. For a long time I was trying to find a competent resource on that subject, that would help me to consolidate my pre workout dynamic stretching routine.
In case of bodybuilding, this book does not offer that. Furthermore, I would suspect that it does not work for other sports as well. So, what seems to be the problem?
Simply put, the book does not provide enough information (almost neglects) the dynamic stretching of: biceps, triceps, back, abdominal muscles, and hips. The 85% of the dynamic stretching exercises refers only to: quadriceps, hamstring, calves, and foot joints. It is hard to imagine that any of these dynamic stretching workouts would work for anyone, except for those athletes involved in running, cycling, soccer, or other sports that primarily engages leg muscles. There is not enough information on how to properly warm-up the entire body through dynamic stretching, and therefore prepare the muscles, tendons, ligaments, and joint for further engagement in training.
This book would be most likely useful for athletes that primarily need to prepare lower body for training. Otherwise, it should be avoided which is not what I would expect having in mind the authors experience, and expertise.
There are few good things to be honest. Presented concepts are well explained, illustrations and accompanying explanation of dynamic stretches are good as well.
