Right. Which is why people don't exercise. That's a lot to ask of people with other things on their plate.
To be clear, I know I should exercise. I just find it very difficult to do so, and it's very easy to convince yourself you should do something else with that energy.
I think team sports are probably the best way to get into exercise. This allows tying the benefit directly into a reward system. I ran long-distance in high school and, without teammates to let down, it was very difficult to push myself beyond the bare minimum effort. Most of us don't have the ability to summon a team sport into our work schedule though.
