I train for a few reasons...for one, bodybuilding is one of the only sports I can say I'm somewhat "good" at. I enjoy playing with my diet and training, it's like my own little science project. Also, I like the way I look and feel. I don't believe most people that say they don't do it to get attention. There is certainly something about the way people look at me when I'm in shape that is almost addictive. And finally, I do have competitive aspirations for the near future.
Pretty much same as you brother. I've never been that great at sports, yet once I got into bodybuilding, I loved the fact that I could accel in it so quickly.
I've always had projects in my life, whether it was building the fastest street car or trying to treat my girl like a princess. When I started bodybuilding, it quickly became another one of my projects, except this project wasn't someone else or working on an object, but it was actual my very own body. I was in complete control of me and the way I looked. By making a few tweaks here in there, I can put on more size or burn off bodyfat. I do it because the science behind it is so interesting. It takes a vast amount of knowledge and dedication to be good at bodybuilding. I don't compete, but I would say that for the short amount of time that I've been serious with it, I've done pretty well so far (went from 178 at 9.5% bodyfat to 225 at 11% bodyfat in a year). Being able to actually dedicate myself to something that produces such great results, in such a short amount of time, on my own body no less...that's probably what has kept me so hooked. Also the fact that it is never-ending. It's not that I reach a certain point and then stop. No, you keep wanting to get bigger or leaner. Always changing.
And hell, I love being in the gym, I love the attention, and I love having somethign to myself. When I sit down with my chicken breast, sweet potato, and brocolli while others are eating mcdonald's, it gives me a feeling of superiority.
Oh and one more thing...I think it has kept me out of trouble. Since I have focused on my body, I no longer drink any alcohol, I stay away from all rec drugs, and all my free time has been taken up by bodybuilding so I have no time to get into any trouble if you know what I mean.
I could go on and on...but bodybuilding has been great to me. I hope to do it for as long as possible and I may compete if I get good enough and have the nerve to get on stage.
