This pair of arm hula hoops is super fun and makes exercise so much better. Made from a high quality elastic soft foam material. We decided to try out just 2 minutes and we are feeling the burn in our shoulders, arms, core, and back. The hoops weigh approximately a half pound and are easy to store or take with you. It feels more like dancing around having a good time instead of working out. Super high quality design and materials. Strong and durable. These hoops are definitely supercharging our motivation to exercise. Super happy. Love this set. Would definitely highly recommend this fun and effective arm hula hoop set. Overall, we are giving this awesome and useful design ⭐️⭐️⭐️⭐️⭐️.
