first of all...I go to the same club as Rockuman and he wasn't even in it for 3 months...I've been in it for a year and it is alot more then just grappling...in Hapkido you learn how to get thrown or fall without gettin hurt seriously and it is an excelent art of discipline and pain tollerence and all sorts of stuff...plus,this Monday we're having a knife defence siminar which will be awesome.... I think TKD and Hapkido are an awesome combination of defence...self discipline, fighting techniques, and alot more...
