Hup Kwon Do is a modern Korean martial art that incorporates elements of taekwondo.
Hup Kwon Do was founded by Lim Ching Sing ("James Lim") in the 1970s. Sing left his original teacher Choi Hong Hi and became affiliated with Choi Kwang Do whose style was more fluid than Taekwondo. Hupkwondo is a synthesis of what he learned from these schools. Hup Kwon Do is characterized by short punches and kicks (i.e., not extending the arms and legs fully, keeping the elbows and knees bent during the strike). It is believed that this facilitates more natural and more rapid follow-up strikes.
