There are only few direct O-Sensei disciples left alive and Yamada Sensei is one of them. This is one reason he is so respected and demanded. The other and even bigger reason is is his high aikido skill, unique style and colossal contribution to aikido.
There is a ton of the warm up exercises and variations of each one, just like the techniques and the entrances. Changing a speed of the same move can make you feel different. No matter where you do aikido – a class is going to start from a warm up most of the times. Warm up exercises are usually the simple ones to do. They are about stretching, breathing, unlocking your joints and preparing your body for a harder work. You are trying to get a detailed feeling of these little parts of your body, preparing your mind also and concentrating on the present moment. These simple moves will tell you how hard are you able to go this time. You must try to remember this every time you start a warm up. It’s not only a tradition.
