Cycle of chest hair

I actually would like to add an image to this cycle for the fitness guys! The next step brings the guy back to the beginning with a bare chest.

Since I started going down this path with Beachbody to get fit and healthy, I have come into contact with a lot of people who have success stories already. Many of them are men, and I have noticed a pattern when looking at before and after pictures: they almost always seem to have bare chests once they have reached their goals.

Now I wonder, is this because of a girlfriend, or just personal preference? Anyone wanna put in their two cents on this? I am genuinely curious! haha
