Re: This "coaching" technique disgusts me
so you are telling me that hanging upside down with all the blood rushing into your head and then being hit is a bad thing? never seen anything like this before and dont need to see any science to know that it is absolutely positively retarded.
side note, i am aware that you can body harden/deaden your nerves in various areas of your body but i am almost 100% sure you cant do the same thing with your face and head.
