I was really into natural bodybuilding in college, and quit to pursue running. Being jacked really isn't this impossible goal, and no, nobody respects you for it. Like running, they think you waste too much time on a useless fitness hobby. What's more, when you're jacked, they assume you're stupid, shallow, and vain. Frankly, I get more romantic interest now, at 140 lbs than I ever did at 175. People told me I looked gross. But I don't really care. You have to do what you enjoy. I enjoy the act of running, and the pursuit of fitness you can take outside of the gym.
