Inseong Jang Biography

Inseong Jang was born on December 17, 1988, in Seoul, the capital of South Korea.

South Korea is well known for its martial arts tradition, activities to which most of its population is well educated. Jang was no different, with his involvement in Korea’s prime self-defense style, Hapkido, starting at the age of 15.

His interest in martial arts developed from his mid-teens all the way into Inseong’s adulthood, with the young athlete going on a deep dive into martial arts studies, which led to Jang taking a university degree in the subject. His learning of combat was not strictly academic as the young Korean went on to achieve black belts in hapkido (4th degree), taekwondo (3rd degree), and judo (2nd degree) while competing extensively in all 3 MA’s.

After graduating from college on May 2013, Inseong started looking for another challenge in martial arts, something that excited his competitive nature. He found that feeling in Brazilian jiu-jitsu, then joined Choi Won Choi’s BJJ academy in Seoul. Jang progressed through the belt system always under Choi’s tutelage and eventually became an instructor at the academy as well as a professional athlete, earning his black belt in 2018.
