If you are looking to add a little more fun to your exercise routine, try hula hooping! Hooping exercise isn't just for kids—it's a great workout that can give you a similar calorie burn to that of step aerobics, kickboxing or boot camp classes. Plus, when you have fun with your workouts, you are more likely to stick to them. You don't have to own a specific type of hoop to enjoy hula hooping, but if you are serious about burning calories and adding muscle, you might want to consider using a weighted hoop—one that is in the one- to two-pound range. How many calories you burn hooping depends on your speed, weight and gender. To see how many calories you burn hula hooping, use the calculator below.
