I've been training BJJ for about six weeks and I'm completely addicted. With that being said I'm a little confused about how intense I should go when I grapple. A little about me; I'm a former Marine and current LEO. I've trained alot in different Self Defense and hand to hand tactics. I love the fact that in BJJ you roll or spar daily, to use the techniques you've learned. As I train more I am noticing different training partners roll at different levels of intensity. Particularly there is on guy who goes at about 110%. He regularly uses forearms across the face, uses elbows to push of and yesterday even used his fist to push my face down on to the mat. When going for subs, especially arm bars he backs into them 100%. I've grappled everyone in my gym and no one else is like that. My instructor even sometimes told us not to do these types of things, while teaching a technique, because that is "dirty" Jiu Jitsu. this guy obviously doesn't take heed to it. Oh yeah He's also a white belt (3 stripe I believe). No else in my gym rolls this way. (At least the ones I've rolled with) When ever I roll, I try to use technique and stregnth, as much as I can. I train cause I enjoy it and to learn things I can apply to my profession. To those of you who have been Grappling for a while how do you handle people like this?? or is this how it's supposed to be when you roll in practice? I could do these things also, but I'm not trying to hurt anyone and I don't wanna any injuries either, which is what this willi eventually lead. I haven't said anything to him about it, cause everyone else he rolls with seems to deal with the same thing and doesn't say anything either. Plus I'm the new guy so I don't complain. Any comments would be appreciated.
