Smart Hula Hoop

Auto Spin - With its centrifugal ball’s help, you can now do your daily hula hoop goals without exerting a ton of energy and time. The ball provides a bit of force to the hoop when spinning — giving you that “effortless” workout dream.
Adjustable size - It can change the size of the hoop's inner circumference to suit a person's waistline.
Durable and environmentally friendly - Made of high-quality ABS material, the gravity ball is made of soft silicone, you don't have to worry about it breaking when dropped on the ground.
Safety - The products are linked with safety elastic straps to prevent the harm caused by the buckle falling during the movement.
