I was visiting my friend Joanne last night at her cute apartment when I noticed her hoola hoop! Aside from surfing on a regular basis, she uses a hula hoop for exercise. So I tried it out. I forgot how much stomach and butt muscle you use when you hula! Amazing. I owned one as a kid, and hey, it's never too late to be a kid again!
You can purchase some on ebay or Amazon.com. Be careful of the hula hoops specifically designed for exercise. I read the customer reviews and it seems that there are a ton of complaints that those type of hoops really hurt and cause bruising. So read reviews before you purchase. What a fun way to exercise!
