I decided that I wanted to compete in grappling this semester, and my BJJ club just sent me an email about an upcoming tournament. http://www.prokarateweekly.com/Story101.htm I am, of course, highly excited/terrified about this tournament. The only competitions I've ever done before were tournament karate and special divisions (kickboxing, etc.) run at karate tournaments. I've done BJJ for about 8 months over the course of the last year, and judo for about two months in the middle of that. I plan on entering the novice division. I'm around 145, so I'm not sure what division I'll weigh in at. My big fears are the following: -Someone throwing all their weight into an armbar and breaking my arm. -The fact that the no-gi division allows leg locks, including heel hooks -Wrestlers. People who wrestled in high school for 4 years and then do BJJ just terrify me. Any advice for an upcoming grappler?
