I have been studying the martial arts for quite some time now. I have studied Kuk Sool Won, Shotokan, Kenpo, and Ninjitsu regularly. I have also dabbled in Hap Ki Do, Tae Kwon Do, Go Ju Ryu, and Jeet Kune Do. Out of all the styles that I have studied, I believe the most versatile is Kuk Sool Won. This is because Kuk Sool is a combination of martial arts. Translated directly to English, Kuk Sool Won means Korean National Martial Arts Association. Kuk Sool, which was developed by In Hyuk Su, incorporates the Korean Martial Arts style of past and present. This includes Tae Kwon Do, Hap Ki Do, and Akido to name a few. It is a soft style while at the same time it is a hard style. It is the yin and the yang.
