I purchased this from Amazon with the intention of using it for a diet focused on pelvic alignment, but due to a misdescription by the seller at the time, it turned out to be for children. Since no one in my household will be using it, I'm offering it at a low price to someone who can! This hula hoop is excellent for correcting pelvic misalignment and directly working the inner muscles. It seems to be effective for creating a defined waistline. - Color: Yellow - Size: 50cm diameter - Quantity: 1 - Intended Use: For children
