I had this thought, and it seemed to work, for the little bit that ive done it. I dont do it often, but if other people think its a good idea, ill do it much more. What I did once in a while was grab a partner around my size and strength and tell him whats up, "Hey, I want to get grapple just for getting stronger, will you train with me?" What I did was both of us would use VERY little technique, maybe an underhook for escaping sidecontrol, or an upa, but anyway...We would grapple as hard as we could. We would go 110% strength 5% technique. No submissions, all we worked for was positions. When someone achieved mount, he tried to force his way to the back. Once someone got the back, we started over. But escapes were like, pushing a guy off of you and quickly rolling out. Or grabbing his hips and throwing him off of mount. We never slam each other, because thats just kinda rude. What do you guys think? Would this give you grappling functional strength?
