If you keep that perspective on things, it gives you the knowledge of why it's so important to make yourself a wide aerobic base and then build your anaerobic stuff on top, and why you need to have some power endurance, because you need to be able to punch over and over and over without getting fatigued. Interesting. I've just got a question about that. I hear all the time, a lot of people, I've got a lot of friends who say, oh yeah, I really want to do jujitsu, but I think I just need to get fit first.

When you start jujitsu, everyone's going to maul you and everyone's going to take away your energy reserve.
