Exercised

Mostly choir-preaching here. I suspect most people that are not exercise-aholics know intuitively that we have a natural resistance to exercise for exercise sake.
Good coverage on the evolutionary and biological aspects.
And does reinforce, of course, that although we are resistant to exercise, it does do us a lot of good. And there is no doubting the “high” you get is part of some evolutionary goal to get us to do it more.
