! Yeah ! it is for real but you have to develop the power to do those things , it does ' nt come easy , body mechanics and stances , and the last but not least the power to make it happen . The sifu who demo that punch on youtube spent alot of time perfecting the technique so that ' s why he could do it .
Practice on the sil lum tao form very slowely like you ' re doing chi kung and breath normally , then practice on those bean bags that they sell in a martial stores . Condition your fists on the bean bag , when you hit the bean bag it becomes hard and that ' s how you can condition your fist and be able to achieve that one inch punching technique . As times goes by for you try and hit a piece of wood , and see the results . And from there you decide what you really need to do . And if you people don ' t believe me then find your own way of achieving that 1 inch punching technique .
