Nothing wrong with both! I started when I was 11, but was interested since I was about 7 or 8, my dad's barber was a national competitor and his wife did some competitions herself, thier kids were pretty beefy.
Indirectly, maybe. I work out so I can be happier and more confident about myself and my body. This is something I'm diong for myself, for life. Not to hit some chick in the sack.
I'd have given up really quickly if that were the case.
