I wrestled for two years in high school (a long time ago...) and we would always go nearly full-intensity when live wrestling during practice. Since starting grappling/bjj six months ago, I've been having trouble throttling the intensity while rolling during randori. It is like I have two settings: practice-move-mode and competition-mode. I try to take it easy, but accidents sometimes happen when the other person and I have different intensities. I don't want to seriously harm anyone. (Ironic despite the nature of the sport, I know.) So how do I relax more when rolling?
