In February 2018, my left leg became paralyzed and I underwent surgery for lumbar spondylolisthesis. I have always played some kind of sport since childhood, swimming, soccer, karate, surfing, marathon running, road biking, etc., but after the surgery, I was not expected to be able to exercise for about 2 years until the bone set, so I wondered if there was any training equivalent to exercise without exercising?  I searched PubMed, a database of medical articles, and found the Wim Hof Method, which reduces pain and exercises all the blood vessels in the body.　And the exercises are done while sitting in a chair or lying on the floor!!!  Various academic papers also reported on why the Wim Hof Method causes health changes. In fact, as I continued to train every day, the things mentioned in the papers happened to me. Thanks to the Wim Hof Method, the paralysis in my left leg has been restored, and I can now run a half marathon as before. I am indebted to the Wim Hof method. So I became an instructor to spread the method to those who need it in Japan.
