I know that sounds like a no brainer but here is my predicament. I have never trained before and am looking to start out. Marcus teaches at a small gym near where I live. But the gym is a martial arts gym where the training revolves around several areas not just BJJ. Which I don't mind but I am mostly interested in the BJJ. Marcus teaches the BJJ classes but the belt system is intergrated with the other styles (kick boxing, pankration) as well. They have their own unique belt system. Should I just be thankful to train with Marcus and concentrate on learning the basics before I worry about getting into a traditional belt system or should I find a gym where the focus is solely on BJJ. Any thoughts would be greatly appreciated. I live in Vancouver area and there are lots of gyms.
