I was thinking about a different way to teach BJJ. Here is the usual way I teach:
5 minutes warm up.
Teach two or three techniques for 30 - 35 minutes.
Do some "hole" training i.e. One person under side control for three minutes trying to escape, when he does another guy jumps on; One guy playing guard for three minutes while his opponent has to pass.If he passes then a third partner goes in the guard.
35 minutes of rolling.
This is the way I've always been taught and seems to yield results. However if you have people of many different belt grades it means that sometimes you're teaching above or below some people's levels. Generally you only want to do 30 minutes of technique and the rest of the class is drilling or rolling.
So I was thinking about this for a class format:
Class starts at 6pm. At 6.15 pm the whitebelts get taught in one corner of the class. The rest of the mat is open mat. At 6.45pm the blue belts are taught in one corner of the class while the white belts roll amongst themselves and whoever else has shown up. At 7.30pm the purple belts and above are taught in one corner of the mat while the blues get to roll in the open mat with the whites. From 8pm to 9pm the mat is open for everyone to roll together.
Why do you think? Pros, cons?
