LMAO. I'm 35 with bad genetics and years of abuse to my body. NO ONE should have to see me with my shirt off. 5 years ago, I was 290 with a fat free mass of 161. Now I'm 280 with a fat free mass of 223. I'm still ugly as sin, but it is nice to know that, for the most part, I am the baddest mofo wherever I go. It's my trip, my ego and my motivation. I aint just fat anymore. I giggle at the metros. They stop puffing out their chests and acting big and bad and don't talk near as much when I am warming up with what they are maxing out at. All of a sudden, they get all serious. I know this is stupid and immature but I like being the alpha male almost everwhere I go. Not everywhere, mind you. There are some mighty big people at some of the gyms I visit. I guarantee exrx has some too. But then again, that's my motivation. I want to be stronger than you. I want to be stronger than I was yesterday. To hell with the way I look. You may look pretty, but I can still kick your ass.
Sorry for my rant and my ego trip. I'm not trying to be a internet Rambo, but I think the motivation for most of use here are for one of three different reasons. Either you are vain and want to look good, you are insecure and want to be better (me), or you are unhealthy and are going to die if you don't make some changes. If you say you just want to be fit, then what is the point of working out? Don't you want to be better than you were yesterday?
