Muay Thai is recently gaining popularity in Japan not just as a martial art, but also as a method of exercise. We visit a Muay Thai gym in the city of Nagoya where all the personal trainers are professional fighters. Whenever a fight nears, they have to go through the grueling process of cutting weight, but luckily, they have delicious, yet healthy low-fat-low-carb staff lunch every day that makes it all a little easier.
