CrossFit’s wall ball exercise is an example high functionality and the marked carryover of cardiorespiratory benefit to sport and human performance in general, writes Coach Greg Glassman.
We see the bulk of human action as being composed of a limited number of irreducible fundamental movements. These fundamental movements we call functional. When you review the list of factors or exercises associated with significant neuroendocrine response, they largely or completely meet our requirements of being fundamental, elemental or irreducible, and universal to sport and life.
Currently we see each major functional movement carrying with it a cardiorespiratory capacity that can be developed independently and in conjunction with other functional movements to provide a superior cardiorespiratory response.
