Hey HGH, don't know how I missed this thread. Congratulations on picking up a sport that you like that's a great workout for you!
Boxing is an excellent way to stay in shape! It's very challenging, and I liken it to human chess. Obviously, speed, strength and endurance are very important, but there's a ton of strategy and learning of your opponent.
I've taken boxing and BJJ as workouts over the years. Both are great workouts. The BJJ was extremely tough on my joints, and I was prone to injury. Boxing seemed a bit easier on my body, but everybody is different.
If's funny. I think the one thing that helped me from boxing is I'm more relaxed in a situation where someone throws a punch at me. I think it's just human nature to flinch, close your eyes or cover up when someone swings at you. You learn pretty quickly to keep you head up and your eyes open! LOL I don't consider myself much of a fighter, but after training a bit, at least I feel like I could defend myself.
I'm not too quick, so I'd never be a great fighter. My best attribute is that I can take a pretty good beating! LOL I guess having a bunch of brothers growing up had its advantages...
