"Stand facing a wall. Reach out with both hands, palm outboard, thumb down, find the place to stand where you can touch the fingertips to the wall at the limit of extension. Stand up straight at maximum reach. Now just turn your hands palm up. Your fingertips are now 3-4 inches from the wall still fully extended -- but shorter."

I must have a different build, cause no matter how I do this, my fingers are still touching the wall. And yes, I did it fully extended. Weird huh.

I like the resonance theory. Kinda subscribes to what Systema's wave power is like.
