I was fat as a kid, hated PE class, and even went to a fat camp once. After moving out (and coming out), I wanted to lose weight and so I wasted several years thinking the key to looking good was just to run on the treadmill and do Atkins. Eventually I realized that I was just becoming a smaller fat person after a loss of over 70lbs, so I began to learn about bodybuilding, strength training, macronutrients (e.g. consuming massive amounts of protein) and anaerobic exercise (e.g. moving heavy iron). That's when I learned about real bodybuilding.
