Strength with the aid of the "sphincters".
Greg Inglis, Australia's national sporting indigenous sporting hero has retired. His strength and athletic abilities have been hard to surpass on the field. I just love this image depicting such strength and tenacity in his play. Notice how he has his tongue just poking out to the right which is one of the components for switching on the anti-gravity response with strength. This is often missed as it is hard wired into our neurological system. This shot, is classic of how this sportsman naturally uses his inner network of postural organisation.
