Once again Delaware Jiujitsu hosted Professor Dave Kama for a seminar. Professor Kama is a member of jiujitsu’s “dirty dozen” (the first 12 American jiujitsu black belts), and known as Rickson’s top student. Professor Kama received all is belts from Rickson Gracie. He taught a three hour seminar consisting of Rickson’s “invisible jiujitsu”, using weight, leverage and connection to make jiujitsu effortless and even more effective. Delaware Jiujitsu is one of only several gyms in the USA where Dave Kama has taught these techniques.
