Definitely number two. I don't need, or really want, people to be super impressed with me physically in real life. I like to think my engaging personality and boyish charm will win the masses over. Being in shape is just icing on the cake. Also, it's more of a shock factor when they see that you're in shape. When I first moved back to Hawaii I had a part time job at a vitamin store. I left my work shirt at the store the previous day because I changed to go to the gym after work. When I got in the next day and quickly changed back into my work shirt one of the guys said, "Daaamn! You're shredded!" The resident teen hottie just looked at me but didn't say anything but her attitude towards me changed a lot. She was a lot friendlier and ask me stuff like did I play sports and make jokes implying that I had an easy time getting girls. One time her friend came in and as we were all talking and joking around her friend asked me, "Can I see your abs?" The girl, the one who worked at the store, just jumped all over her in the sense that she kind of pushed her and told her to shut up. I guess her friend didn't realize that by asking this it betrayed the fact that my name came up at some point.
So when a person takes off their shirt I'd rather them be pleasantly surprised then disappointed when you just look fat and bloofy without a shirt. Especially when they have higher expectations with the big guy because he looks muscular in clothes.
