One of my passions in Taekwondo studdies is Poomsae Boonseok (Pattern analisys) to find practical applications or meaning in the movements in our forms. In Taegeuk Oh (5) Jang there is a technique which follows a knife hand outer block in middle section where you do an elbow strike where the hand is supported by the other hand (I am NOT talking about the elbow target strike that follows the side kick/ hammerfist strike combo by the way). Now usually when we do the round elbow strike in basic technique training we do is with the non striking arm pulled back at our hip, but in Taegeuk Oh (5) Jang we have the non striking hand placed on the striking arms fist. The question is: What is the purpose for this placement of the non striking arm? Do anyone have any idea or have you ever really even wondered about this? I have an application for the move, but I am very curious as to what other people think about the move.
