I learned a simple technique early in my practice and created many muscle-specific stretches for the whole body using this simple way of stretching. I use it with all my clients and in my stretch classes with great success. There is a related testimonial here. It is not 'static' stretching or 'dynamic' or 'PNF' and we don't go 'ballistic' doing this. Designed as a way to communicate with the muscles, each stretch is held for two seconds with seven to ten reps. Do two sets a few minutes apart for best result. It is the most sustainable way to stretch I have seen and is appropriate for rehabilitation and maintaining vitality in our body at any age. I know of nothing better for this purpose. We can do it cold and it is an ideal initial warm up for the muscles. It never creates injury, it allows greater strength and speed, and helps avoid soreness and spasm.
