What do Girls like more in a guy's body?

Broad shoulders and a nicely developed chest is usually what girls look for on a very primal level. Of course you will get more rational preferences, but deep down, broad shoulders means that you are strong and capable of hunting and protecting. This still matters on a subconscious level, even though we girls are quite capable of looking after ourselves. But generally, an all round fitness, despite any little bulges or skinniness here and there, is very desirable. I think you should just keep up with the kickboking. If you get to be anything like Tony Jaa, I think you are on the right track.
