Fitness is a curve. You can be Lance Armstrong, or you can be really out of shape at the opposite end. People enter the curve wherever they are and then they can move up the curve, by better nutrition and better exercise. ↗
Me personally, I'm a guy who it took a long time to figure out what I'm supposed to be doing. I relate to a lot of that finding oneself a little later in the game, or being thrown a curve later in the game. ↗
