Let me just put on my black belt before I make this post.
Only the smart fighters come out on top. These guys may have large upper bodies, but you have to be very aware of space and angles that are created when someone opens themselves up to attack. You can simplify your unarmed combat arsenal to striking, throwing, breaking, and asphyxiating. Not only is it required to be skilled in at least one of these for you to be dangerous, but these tools are extremely perishable if they aren't as sharp as your mind. It's much harder to maintain a lethal understanding of unarmed combat than it is to grasp it.
Aside from that you need exercise. One of the main problems with these beefed up brawlers is that they gas out easily because they're cardio is shit and that is because all they've been told is to lift weights and run on tread mills. Your knuckles are extremely sensitive, so why the fuck would you lead to box if your upper half is conditioned better to just monkey grip shit until it's dead? Because they're stupid fighters who only fight for money and fame and not because they appreciate martial arts at all. Be deliberate in how you condition yourself. Your body shouldn't look like someone took a the torso off HE-MAN and put it on Cheetara.
Basically all you actually need to learn to turn your body into a weapon is how to be good at at least one of those four disciplines and to strengthen your body. Don't get caught up in style wars because they all have something to give provided you can take whats good and discard the rest.
