“A command I heard CONSTANTLY when I started Aikido training back in 1993 was one simple word – relax. I would try to do a technique and a senior student would stop me and say – “just relax”. Then I would exhale, try to release the tension in my shoulders and try again. Again I would be stopped and there’s that word again – “relax!”.
I didn’t have a lot of life skills at that time but one thing I thought I knew how to do well was to relax! Why was this so difficult?”
