As it says in my sigline, I'm 6'4 and 230lbs. I'm not so much out of shape, but not in the best of shape either. I've also been in my fair share of fights, won some, some lost. I "know" how to throw a punch when standing up and have used my body weight/strength when on the ground. But sometimes I wonder if this is truly enough. I'm a fairly busy guy between work, my family and riding my with my crew ) ), so I'm afraid that I don't have a whole lot of spare time on my hands to jump headfirst into a martial art for the full experience and yada, yada, yada. I'm not out looking for trouble either and I will always walk away from it if it is an option. I just, basically, want to be able to defend myself if a day comes that I would need to where my normal "knocking someone out" or whatever wouldn't work so well. Where should I begin to look? Thanks.
