what're some of your fears when you train in aikido? One of my fears is actually breaking my arm (I broke it before when I was a child and let's just say, I don't want to ever experience it again). Just today, while practising kotagaeshi (tenkan), I almost broke my arm. As I commited a stomach punch, the nage stepped out of the line, and almost snapped my arm while he torqued his body to do a tenkan movement. After that, I started punching like a pansy...I didn't want that arm snapped!
