Why do you train BJJ?
I enjoy both the mental and physical challenge. Besides being a great workout, I find that to be really good at BJJ, you always have to be thinking about your next combination of moves or you may find yourself sleeping on the mat.
What advice do you have for novices?
Learn to relax and accept that everybody gets tapped. I say this so that students stay injury free which is the biggest impediment to improving. Once you get your ego under control, you are more free to learn and improve your game.
What has BJJ done for you?
BJJ has given me confidence. It has challenged me both mentally and physically. BJJ has allowed me to meet a diverse set of friends from all walks of life and around the world. I find that for the most part BJJ practioners are some of the nicest and most genuine people you will ever meet. Meatheads do not last long in BJJ.
