How closely are you looking at your athletes?
"Loss of mobility is sometimes the only way the body can achieve a point of stability, but that stability is not authentic. It is often seen or observed as stiffness or inflexibility, but on a sensory motor level, it is part of a system with no other available choice. It is basically engineered dysfunction at a local level to allow continued physical performance at a global level."
