We do use verbal tap outs per say, but my concern is about the speed of some of these takedowns. the other day he took me down and I honestly didnt see him grab me until I was on the ground, it was so quick. it was my turn to try and he was telling me that it was not necessary to do it with such speed but he didnt want me to pause through the maneuver. Now, he knows how to fall, of course, and so do I but nonetheless, I feel I should know something he isnt telling me yet so that I can be more confident about putting some pain on him and not injuring him because of a careless mistake. I guess what im trying to see is if I can get any advice from Hapkido or even Aikido instructors on the level of precaution we must have or is it negligible... I wouldnt think so. How wide is the margin between pain and injury? Is there a margin, or is it very easy to go too far?
