We all havev access to the "Scientific" reasoning behind the sine wave, but what is YOUR opinion of it please.
I'm with my friend "Martialist" regards to its uselessness.
If it was that good, it would be used in everything, but at present its used ONLY Poomsae/Tuls/forms not in the Self defence combinations etc.
Also on a side note on some of the forms the hands come back to the waist before striking this to me is detrimental. try have someone in boxing gloves punch you full speed in the face as you do this block/strike and see if you can bloke it BEFORE he hits you in the face
A man is but the product of his thoughts what he thinks, he becomes.
