My wife is a TKD black belt. When I met her and when she learned Chinese wrestling from me, I threw her and expected that she knew how to do a break fall. I was wrong. After that, I won't expect all black belts know how to do a break fall. The break fall training may not be part of all black belt testing requirement.• I do not recommend TKD practitioners fall to techniques or throws without sufficient training in break falls. It is like asking a yellow belt to train his punch by attempting three-board breaks.
