ABOUT STEPHAN KESTING AND GRAPPLEARTS.COM My name is Stephan Kesting and I’ve been doing martial arts for more than 37 years. The grappling arts have been my main focus for about 25 of these years, and now I’m a Brazilian Jiu-Jitsu black belt, and also a certified instructor in Erik Paulson’s Combat Submission Wrestling. In addition to the grappling qualifications, I’m also a black belt in Kajukenbo Karate, an instructor in Dan Inosanto’s Jun Fan JKD, Maphalindo Silat, and the Filipino Martial Arts program. I’ve studied Japanese Judo, Russian Sambo, various Chinese Kung Fu systems, Brazilian Capoeira, Muay Thai Kickboxing, and many other martial arts. I’m not bringing up those qualifications to boast. The reason I mentioned them is to establish that I’ve been around the scene, trained with a lot of different people, and have a good understanding of the challenges that grapplers face on the mats everyday. I know quality and can recognize stuff that really works when I see it. Grapplearts is my company and we’ve been online since 2002. That’s a long time, and we’ve produced a ton of instructional products, continuously refining how the material gets taught and presented in order to make it easier to learn. The goal is to get you the best information in the easiest-to-learn format, period! END USER LICENSE AGREEMENT https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
