These cuddly critters are gettin' their sweat on!
Did you make a resolution to get fit in 2013? Welcome to the club. It's easy to say you want to be healthier, but it's much harder to keep up the momentum. Exercising with a buddy is one way to stay on track. And who says that buddy has to be a person? These active pets inspire us to keep breaking a sweat. Laughter's not a bad workout, either.
