I have been active as a coach for more than 8 years and practicing martial arts for more than a decade. Upon my first contact with Martin’s and Jan’s Grappling Development program, I was certain, that nothing I have seen so far could have a more significant influence on how I think about movement and physical performance. This program is an absolute necessity if you want to keep on grappling in the next 10, 20 or even 50 years and stay free of chronic injuries. The concept lets you in on a number of principles, games, and exercises, that will make your training more efficient, fun and at the same time help you to improve on many levels. That being said, everything they teach is very closely connected to grappling and BJJ, so you don’t need to worry about adding an extra training time besides being on the mats (even though you will want to!).
