Daedo Suk Kudo Chongbonbu is a martial arts studio in Busan where people train in karate, kickboxing, judo, and jiu-jitsu. It also runs weight-assisted diet workouts done while wearing protective gear. Members who register a fingerprint can enter and train on days without weekend classes, even as a white-belt beginner. Air conditioners and heaters are run at high settings, so indoor cooling and heating are distinct.
