Chatchai Sasakul is the owner of this gym who turned pro in 1991 and captured the WBC and lineal flyweight titles with a win over Yuri Arbachakov in 1997. He defended the titles twice before losing to Manny Pacquiao by knockout in 1998 to earn Pacquiao his first championship title.
I met with the champion, who just trained next to me. He was incredible indeed. Just tried to follow what he was doing, get sweated a lot.
One of the best Muay Thai Gym in Bangkok. Trainers are friendly and experienced, especially "Kru Neung" for Boxing.
