Not just how it looks, but how it moves and feels. For instance, consider taking up yoga, which requires you to stay grounded in the moment, focus on your breathing and observe your thoughts and your bodily sensations. Or try a mediation exercise where you have to move through your body bit by bit, examining its sensations.
Not so into downward dogging or reciting mantras? Make a list of all the things you love most about your body and why. If you find yourself writing more cons than pros, take a moment to examine why you feel that way and how you can change it. And make sure to find something good even in the parts you're not that fond of. For instance, you might not be crazy about your “big” boobs, but try to remember just how bangin’ they looked in that pink dress at your sister’s wedding.
