I was looking at a thread in General Survival, and it got me to thinking. So rather than hijacking his thread, I thought I would start this and ask everyone. Do you train or study any type of hand to hand combat? If so, what have you found effective? I have not really had any formalized training, but have worked as a bouncer for a couple of years, and work in light security part time now. I am looking at taking some classes in ju jitsu, and using the treadmill more to tone and build up some endurance. I am sparring occasionally with my son, who is doing some amatuer events in the cage fighting events. His first fight was a King of the Cage event, he was not on the card, but got to be one of the warm up amatuer events. Here is a picture of him and his opponent. His original opponent and the guy he eventually fought both cancelled so he had to fight 2 weight classes above him. He is 5'9", and 175 lbs, and his opponent was 6'1" and weighed 205. (He lost, but I got to hand it to him to get in the ring!) Do you work out, or are we in trouble when we run out of bullets?
