Doing what for vanity?
Just the weight training, or extra core exercises?
If you are weight training for vanity it's called body building and there is a ton of crap written on forums every day about it. Basically you address muscle hypertrophy at the expense of all else.
Funnily enough, look at the team sprint podium from this years nationals (last night) and there's no overdeveloped upper bodies or beach guns.
