Wrestling made simple Well not really but I was talking to one of the lads about core principles in grappling and wrestling and there are a few universal truths that I believe hold true: 1) Its all about space: if you are in a dominants position you need to kill space its your enemy, anything from body lock takedowns, to side control pins to being in the guard. If you give your opponent space you give him an out. conversely if you are in trouble you need to create space: be it framing under side control, digging under hooks in the clinch, pushing the head away whilst body locked etc all are looking to essentially create space in order to move. 2) it's also all about the hips: whomever controls the hips usually wins: be it stood up shooting a double, in guard or mounted whomever managing to gain control of the hips and stop there opponents hips moving usually wins. The control of Hips and Space really covers everything in grappling. Three bonus points: Hips again, whomever has the lower hip level usually wins the takedown game. Whomever has dominant head position usually wins (this applies equally standing and on the ground.) This also relates to breaking an opponent's posture by controlling his head. (At the risk of sounding like Dominic Cruz)who ever wins the underhook battle is likely to win the match.
