I understand and read Naked Warrior and Power to the People, which by the way were great!
Interesting point Steve W. I guess the skill to generate high tension is the gross motor skill while the smaller controlled movements are fine motor skills, and everything we do has at least some of each. I got a bit confused because whenever i read something about fine motor skill they always use examples of the hand, but keeping your legs straight while doing a handstand is definitely the more fine motor part of the posture.
