Now if I recall the original posters native language wasn't English so maybe a misunderstanding of terminology or maybe a radically different approach, but in almost 2 decades in martial arts and 10 in internal arts have not seen anyone use zero force and have someone unbalance.
I've found though in martial arts that using the language of origin of the art when 'naming' techniques or ideas is best. In karate we can say 'mawashigeri' and we all know what it means, likewise with 'kime', bunkai etc. I assume there is a name for this 'no touch' idea ?
