I'm a trampoline gymnast (though don't get pictures in your head of me being excessively flexible.. Yes, I can touch my toes, but that's about it!)
However, my chest very small.. Barely even a handful :( and my stomach is extremely toned. My coach wants me to do sit ups and crunches more regularly, however my stomach is already hinting a six pack.. If this got more defined, would that be a turn off?
(On the plus side, I have a decent sized butt and very long legs! But that's aside from the point lol)
In all honesty, I 've never fantasized about a girl with a six-pack, but, to be honest, it's not a turn-off. Every girl attracts a guy in a different way, otherwise guys would only ever be attracted to a single girl. If that works for your look, then there's no harm in it and you can still be very attractive. Don't worry about the chest thing either...
Being toned and physically active is always attractive. A hint of a six-pack is cool, but if it is visible even when the stomach muscles are not tensed, I'd probably be slightly unnerved. I would say you should continue doing situps and crunches to become stronger, but maybe eat more fat. This means you don't have to sacrifice fitness levels, you can control your level of definition, and you get more boobs too!
nnnoooooo... that actually be a very big turn on if you have a 6 pack abs. that would be very attractive. but do you feel very confident showing off your very muscular stomach? and thats very attractive that you have very long legs. the second question is how tall are you? and how would you fully describe your legs?
