I'll take a different angle at it.
What are your goals? What do you want to achieve from bodybuilding?
I ask this cause in these 4pages of replies you got a bunch of people telling you that you are small, you need to grow, blah blah. It all comes down what you want though.
Do you want to compete eventually?
Do you want to just gain a little bit more of muscle?
You won't know this now, but very few of the people that posted on this thread are huge and ripped at the same time. It's usually one or the other, and sometimes neither.
Just tell us what you are looking for and I am sure people will help you out. If you just post pics at a bodybuilding board, they will tell you what to do based on how they see is best ... not how you should be based on your opinion.
I took a lot of the advice here and ballooned up to 260lbs @ 6'3. Then I looked at myself in the mirror and realized I was fat. I don't need that. Noone here is a pro bodybuilder, so could we stop with the bulking to be a pig routine?
You are already pretty cut. Just tell us what you wanna achieve.
If you wanna gain size, first thing most people will tell you is to increase your carbs. Noone became mr. olympia listening to atkins.
