If you find yourself shopping in New York City on a Saturday between tomorrow and June 13, you may want to take a break from the stacks of summer goodies on the shelves and head over to Kate Spade's 5th Avenue store. The designer, inspired by a retro hula theme, is offering free hula hoop lessons from 3 p.m to 5 p.m., weather permitting. There will be hooping professional to teach you some moves, and plenty of hula hoops on hand -- of course you can bring your own, too.

Is this a ploy to just get people into the store? Yes, for sure. Will you walk away a hula hoop master? Probably not. But you might just be inspired enough to pick up your own hoop at home and use it to have some fun and tone your waistline all summer long. Spinning a hula hoop around your middle can burn more than 150 calories per hour.

And, if a few minutes of hooping outside a store sounds like child's play, try a hooping class at a gym near you for a more serious workout.
