If you love to eat but hate to exercise, I've got news for you: You've got to get your butt in gear. I mean, literally get your butt in gear and move your body. Your health is so important to your overall life satisfaction, say the father-son authors of Happiness: Unlocking the Mysteries of Psychological Wealth, that even if you hate to exercise, you've simply got to do it. You don't even need to lose weight. You just need to exercise.

Father writer Ed Diener says he doesn't enjoy working out but found that if he listens to books on tape while exercising and stops his session just before the end of a chapter, he'll want to exercise the next day -- if only to get back to his book.

Health in general can increase feelings of well-being, say Diener and his son Robert Biswas-Diener. Plain and simple: Happier people are healthier people.

The happy guys tell all in the October 2008 issue of The Oprah Magazine. Check it out if you can -- on page 194 -- and give some thought to how you might trick yourself into enjoying exercise. Figure it out and your health and happiness will soar.
