I have been taking Kenpo classes for 2 months. However, I not sure if this is part of the training or if all martial arts classes are like this. When the instructor is showing submissions (arm bars, arm logs, wrist locks) he really inflicts pain and when the I and other students tap, there's a long delay. It's almost like he enjoys hearing us scream out loud. Please tell me if this is the "Kenpo style" of teaching. My gut is telling me somebody is really going to get hurt.
