My main fitness activity is walking or jogging, and sometimes I get a little bored with it. Usually that means it's just time to refresh my mp3 playlist or choose a new route, but sometimes I'm in the mood for a little more. Though the key to a consistent exercise routine is choosing an activity you love that fits into your lifestyle, there's nothing wrong with changing it up on a regular basis. By varying your routine, you keep your body and your mind sharp and keep the workout doldrums away.

Here's a list of some ideas for you to shake things up and try something new. There are some classics here, like horseback riding, rowing, tennis, and boxing. There are also some innovative workouts like adult gymnastics (sounds fun!), adult ballet, meridian flexibility, gyrotonics, and working out with kettleballs.

Not every fitness activity has to happen in a gym. Living a more active life in general, and in addition to your workout routine, will help you burn calories, increase muscle strength, and improve your heart health. Be creative this spring and put some spice back into your workout!
