So, I can't really speak to why anyone else enjoys bodybuilding, but I will speak to why I do. I will make the disclaimer that I do what is probably better termed "powerbuilding", a combination of powerlifting type training with the intent of putting on mass AND functional strength, rather than just pure bodybuilding which isn't always about the functional strength part. For me, the biggest driver to get serious about training again (I actively trained in my high school and college years) was because I'd taken up some bad habits (smoking) and was developing some potentially very serious health problems (high blood pressure, high cholesterol, Metabolic Syndrome and asthma). Getting back into serious weight training has helped correct all of those health issues that could have made my life a lot shorter and less enjoyable, kept me from smoking again, and forced me to clean up my diet. Because of these things I feel better than I have in ten years with energy to burn. It's also about the personal challenge to me, seeing how I can affect changes in my body. The discipline required is something I carry with me into the rest of my life, and I view that time with the iron as my sort of moment of zen a few times a week where I can destress and not have to deal with anything or anyone but myself and the weight during that time. I also enjoy the functional strength I have from my training and, yes, I do having a physique that reflects my hard work and dedication. It certainly doesn't hurt my self-esteem or confidence, especially in a society where 75% of people are overweight. So, at least for me, it's not about compensating for something or trying to stroke my own ego or make myself feel okay with who I am. It's just a natural compliment to who I am, a stress and health management tool, and something that helps me with my goals in life in general.
