Ok, Rodrigo came to our school yesterday for a four hour no-gi seminar. It went really well. He is a cool guy, very nice. I was completely spent after the seminar and sore from head to toe today.
We did a little warm-up and got right into it. He would have us pair up and put us into a position. For instance one would be in side control and the other on bottom. The guy on bottom would try to escape or put partner in guard, the other would try to mount or submit. Whenever one would win we would start over. After probably five minutes we would switch. After that he would go over some mistakes he saw and offer advice and different techniques for escape or submission. He did this with virtually every position you could find yourself in. Very informative. He also went over takedowns and set ups for takedowns for NHB fighting.
Like I said, the seminar was mainly position orientated and it was no-gi. We all had a great time and learned alot. He rolled with many students from white to brown. He is a very humble guy and his jiu-jitsu knowledge and technique is unreal. If you get a chance, take a seminar with him and a private if possible.
