This is 100 shomen suburi. It only takes 3 minutes.
Now why did I put this up here? It is because quite a log of people think that suburi is a warm-up exercise. So I wanted to introduce how we should be doing suburi. The explanation at the beginning is where you should pay the most attention to. And if you do not have an instructor, please see how I stop my kensaki (the tip of the sword).
