Emily has been practicing martial arts for most of her life. Her first karate school emphasized the importance of learning as many variations as possible, catering techniques to individuals. It was a combination of several traditional and modern Japanese styles that also integrated aspects of Judo, Japanese Jiu Jitsu, and practical self-defense. She trained in Kyokushin and Shotokan while living in Japan for three years, learning sparring techniques and teaching kata to fighters. Upon her return, she trained in Muay Thai and Jeet Kune Do for several years and ran cardio kickboxing classes on Zoom in 2020. In classes both on and off the mat, she expresses her belief that martial arts help to form some of the best communities in the world, allowing practitioners to better understand and push the boundaries of their own potential while forging practical skills and self-confidence. She applies her knowledge of and experience with martial arts to her academic work as a Ph.D. candidate in Philosophy of Religion at Columbia University, where she is currently writing her dissertation about embodiment, imagination, and virtuality.


Even though he practiced martial arts all along his childhood (mostly judo), David consider that his true martial arts journey started in 2003. After a couple of year of Aikido and kick boxing, he discovered Shorinji Kempo, a Japanese martial art he consistently got involved in until 2019. Over the years, he won the french Taikai (annual SK tournament) three consecutive years, ended two times at the fourth place in European and World competitions, and participated in numerous international events, as a demonstration performer (Embu). After a two-years break due to COVID crisis, and an expatriation to New York City, he started a fresh new curriculum in Krav Maga with Tsahi Shemesh and got his instructor certification last July. David firmly believes that martial arts changed his life for the better and expect now to give back to others what was given to him years ago: technical knowledge and self-defense skills of course, but also self-confidence, and rigor.
