Larry, what style of Ju Jitsu are you doing? I took aikijujitsu years ago. This one combines with hard and soft arts, which was very hard. It took me almost a year and half just to get a yellow belt.
Brazilian Jiu Jitsu with Gi
http://veritasbjj.com/We do 30 minutes of cardio, then 30 minutes of techniques followed up by 30 minutes of rolling.
I used to box some when I was a teenager then wrestled Freestyle when I was 19/20. In 93 I started taking Wing chun, Chin Na, with some bits and pieces of Fukien White Crane, Chen Tai Chi Chuan, Pa Kua Chang, Hsing-I throw in and not stop till 2003. I studied BJJ/MA for almost a year in 06/07 then the d@mn jeep almost killed me. I could not roll or practice for almost a year and the place had stopped doing any grappling. So spent last year looking for a good place to train that was close to home.
