Aluminum hoops respond better to the inertia in comparison to plastic hoops that tend to warp, losing a lot of the inertia or energy. Therefore it takes less effort to "hoop" with aluminum hoops.
These hoops have a 36" diameter, are SUPER LIGHT at just over 6 ounces a piece and come with a shiny finish suitable for professional performances.
Even if you are not a professional, these hoops are so easy to hoop with that 10 minutes a day will give you an excellent cardiovascular exercise and help burn a few calories too!
