Will hula hooping by itself get rid of belly fat?

It can contribute to: Fat loss - but won't do it by it's self. There's no such thing as natural spot fat loss. You need to lose weight in general & a certain % will be abdominal fat. Eat healthfully & be physically active. Calories burned must > calories consumed. To tighten ab's do crunches, reverse crunches, exercise ball crunches, pelvic thrusts, lying leg raises, side bridge & “bicycling” exercise on your back.
