Most people pump iron to get bigger and bigger muscles loosing sight that it's too much and too fake. When they stop it all comes back down and they end up with sagging muscles and breasts. You're pretty much optimal there without going for an athletic look. Maybe work your back to strengthen and straighten it and get it a little defined if it is not.
Important to always have antagonistic muscles balanced to not get injured in the long run.
That's not necessary really, except for the bubble butt part ;)
Honestly it will happen naturally as you grow older. I have gone from thin to say fit/athletic over the years just from my regular activities. As long as you look good for your given body type that's what matters. You'll have takers :P
*looks around* where are they though? ;.=.; lol and its more of a personal goal than for impressing others (even though I put pictures like this here xD) but thank you for the kind words ^.=.^ its much appreciated
you will haha, If you want some hints though, the easiest way to Bulk Up, I've found is swimming I was a Varsity Swimmer through all my Years of High School and as such, even though I don't swim regularly (anymore), I still have the traditional "V" shape of a swimmer.
PM me if you want to know some swim routines/Exercise routines that really help. :)
