There are a few positives in exercise. You feel better and get sick less often. I am much more alert and find I make a lot less errors at work. People get a “High” from exercising, that is why there are so many people that get almost addicted.

It also helps if you are changing your self to get better or have goals. Time wise or maybe you are trying to win or be the top American finisher.

Also you can think about things in your life, solve problems from work, set goals and plan your day while doing it.
