Henry Clark

10th Planet Purple Belt

Henry Clark is a 10th Planet purple belt and has his purple belt in Choi Shin Do. He has been training grappling for 6 years and also competes as an amateur MMA fighter proudly representing The Choi Institute. Monday night is the perfect way to start out your week with the focus of class being on the students. Depending on who is in class the techniques taught are tailored to the skill level and growth of the class. There is always the constant drilling of basic principles and ideas and the introduction of advance technique to challenge students and get them thinking outside the box. The second half of class is live rolling putting what we’ve drilled the previous hour into practice.


Friday’s class consists of grappling technique and sparring. Saturday’s class consists of dead zones and shark tanks ( where we drill important techniques/positions to build technical conditioning/resistance and muscle memory). I have been training in different martial arts including Aikido, Judo, Sambo, traditional Jiu-Jitsu, BJJ, Grappling, Boxing, Muay Thai, 10thplanet jj, and MMA since 2004. My private classes are tailored to the individual’s needs; as more attention is given to the individual, the learning process is usually faster.
