That's not good get toned up then maybe give it a try, how old are you? It may not even be worth it if your too old. I'm 5'11 and 200 but toned.
You have time, that's not toooo old but if you really want to get your ass in the gym and get toned up,:good but now 23 is bordering on too old to get started they make a big deal out of Sergio starting at 20.
That not setting a very hard goal to beat, but boxing isn't a game you can get hurt brutally as I'm sure your well aware of being a fan of the Krusher.
