Since the age of 12, I have weighed less than 180 pounds in only two different periods of my life. The first was when I was wrestling my junior year of high school. I started out around 185 pounds and the intense training brought me down to roughly 160 pounds and probably single digit body fat percentage. I wouldn't say I was in an unhealthy state, but I used unhealthy tactics to drop that much weight. Working out for three hours on an empty stomach is fairly brutal. So, the other time that I weighed less than 180 pounds? Today. As difficult as it is to eat clean, exercise properly and maintain other health parameters, it's completely worth it. I haven't worn a pair of size 31 pants... ever. It's a good thing my current wardrobe isn't expensive because if I keep this up, I'm going to have to replace quite a few things.
