Myself: I come from a mma/ no gi grappling school that I started going to 7 years or so ago. I did that for about a year and quickly realized I didn't want to fight, don't like getting hit and don't want to spend $80 a month for something I'll have nothing to show for down the road, so I found judo and never looked back. About 3 1/2 years ago a sport bjj school opened up near by and I quickly signed up. I got my blue belt after about 1 1/2 years and have been going 2-3x per week since. I love the sport almost as much as judo. I feel it has helped me in all the obvious ways, but mostly in the guard passing, submission defense, and conditioning in the extra mat time. A lot of the success from bjj in judo for myself comes down to the particular referee and the amount of mat time they allow. A lot of the flashier sweeps, submissions, and back attacks don't work in judo because you don't have the time to set it up, but I still have fun learning it anyways. I also try to go work out with a friend that coaches folk style scholastic wrestling once in a while when I have time. The benefits are huge in the turn overs and conditioning, but I just don't have the time to make a habit out of it.
My area is not a very popular judo area with only 3 major clubs, including the one I go to. So with the exception of small talk at tournaments, I'm kind of cut off from the judo crowd. I'm curious as to if cross training is becoming more popular and what others thoughts are about it in other parts of the states and world. Thanks!
