There's nothing wrong with incorporating a little fun into your workout. When you enjoy the activities you're participating in, you're much more likely to stick with it. So why not inject a little playtime in your workout?

If you have kids, you're likely a frequent visitor at the neighborhood park. While you could certainly lounge on a bench and watch your kids play, you'd probably have more fun if you got right in there and played with your kids. Try out the swings, zoom down a slide, and climb around the equipment to your heart's delight. You can also start a game of catch, tag, or have a relay race.

What's more, you can take the opportunity to do a little strength training. While you're there, take a few minutes to try these playground exercises. Gossip Girl actress Jessica Szohr shows us how each move is done. Check out her balance bends using a swing, hanging crunches, and lunges on a slide.
