Early in the morning, my dog Reuben is raring to go. He wakes me up with tons of licks, and paces coyly around the room until I pull my lazy bum out of bed. He can't wait to get outside, not only to "do his business," but to run and jump around, chase skittish squirrels, and play with his favorite squeaky ball. It's impossible to watch him happily zooming around with boundless amounts of energy without being inspired to get my body moving, too. The next time you see a dog sprinting and smiling, catch its buzz and be just as excited to exercise as it is. If you have a pooch, take them along on your run as a thank for encouraging you to get off the couch and move.
