Personally I dont really care about backing it up either. Im not in it to show anyone up, im in it cause I love the iron. I love the pumps, I love the "me time" in the gym. I love being able to push myself beyond the pain threshold that most people have and even beyond that which some people only dream about. I will never be the biggest, the leanest or the strongest, and frankly, I am OK with that. I have overcome enough in my life where just turning heads is enough for me when it comes to "proving myself".
Lot of my friends tell me I am rather large and comming along nicely and I get some looks in the gym on occasion but for the most part I still feel small......oh well.
