We don't talk during practice, but use gestures and body language to communicate.
Discussion happens after the training - not during.
The Sensei is the only one who should be talking when training. He'll often come up to an individual and almost whisper any corrections, apart from observing these rules of etiquette, the club is very informal. The Sensei can often be quite comical at times, and have us all laughing. I think this is healthy.
