I was a twig growing up, so I actually do feel big now.
I just stepped off the scale a second ago at 222.5 (clothing and running shoes on though), I estimate 10% BF at 5'9.5''
If I posted a pic, no one would say I was big here, but I know I am muscular compared to normal people.
I am pretty happy with my look, but I will keep going just because I enjoy making progress. I also like the endorphin release after just going to the gym and having a good training session.
That being said, I don't feel big by BB'ing standards, especially compared to those guys that have awesome muscle shape, insertions, and full muscle bellies.
I have a friend that is 5'9'' and 185, he has the best physique I have ever seen in person (I've never been to a BB event or anything like that). He is one of those guys that everyone in town knows is a bodybuilder just by looking at him. I stand next to him with 30lbs on him, and I bet some people would question whether or not I even lifted weights compared to him, lol.
