I'm about to do my first day of that deadly middle eastern art, jew jitsu. I've heard this place will usually have you roll a good bit your first day, which is cool with me. I love to wrestle, and I'm not too bad at it for someone untrained. So my question is, when rolling, is it cool to go pretty hard as far as sweeps and positioning is concerned and just take it easy/pure technique with the subs? Or should I one hundred percent only try using the techniques they show me for position too. I ask because wrestling/grappling/w/e is a lot of fun for me, and I don't wanna get to into it to not learn from it. Buttt, I don't want to get so into improving that I don't have fun either. Anywho, any advice is appreciated. I'm excited.
