A Martial Arts Gym in Tokyo - S15.E34

The stage is a martial arts gym in Tokyo. More than ninety percent of the members are beginners, and the ratio of men and women is half. People of all ages, occupations, and different backgrounds gather here to dissipate something in their daily lives. There are lessons at the gym every hour, and the level ranges from diet and beginner classes to advanced classes. What is everyone facing at the end of the fist that is slammed? For three days, I listened to the people.
