I train in a style called Krav Maga....it is based on hand-to-hand techniques of the Israeli military. We spar heavy contact with pads (cups, mouth piece, head gear, shin guards and boxing gloves). The non-sparring practice drills are usually 2, 3, or more against 1. Cardio conditioning required for this style is off the charts. Because we do a lot of many vs. one training, we avoid going to the ground....Basically, I don't want your buddy kicking me in the head while I have you in an arm bar on the ground. So, we practice striking and staying on our feet (tons of sprawl work). But, because so many guys train BJJ, we practice from our backs, in the guard, in full mount, etc....Our goal is to get to a dominant position, ground and pound and escape. We are always looking to get to our feet or keep our feet underneath us and find an exit. This is not for sport, not for competition....It is for survival. The fight is never over until you are home safely, drinking some whiskey and telling your chick about it.
