Along those lines, there is a playful routine that can help you lose weight and tone up, all at the same time.
For decades, the hula hoop was a popular children's toy. Now, adults are getting in on the swing of things, using the plastic rings to get in shape.
Keeping the hoop going is part of the challenge, and instructor Noelle Powers says the secret to control is the right fit.
"It is easy with the right size and weight hoop, because the heavier and larger the hoop, the slower it revolves around," she said.
In fact, the hoop is good for toning the entire body, not just the waist.
"Part of the beauty of hooping, with these kinds of hoops, is you can start to take it all the way off your body, and start to do a lot of hooping around your arms which builds your arm muscles all the way down to your legs," Powers said.
They are some fancy moves that help to burn calories.
"It's more aerobic than it looks," exerciser Drew Fields said. "So you actually get a really good workout from doing this."
Weighted hula hoops are bigger and heavier than traditional hula hoops and are available at many sporting goods stores. Lighter hoops require more energy to keep them going. Heavier ones are easier to keep going.
