Just by turning the waist slightly, it can bring about 4 times more waist-circling force than ordinary fitness belts, which can effectively reduce fat and burn calories, and there are massage balls in the circled area. While rotating, the massage ball also relaxes your body, allowing fitness and massage to proceed at the same time. Detachable design The fitness hoop has 6 detachable parts and has a hidden high-elastic steel buckle design for easy assembly and disassembly. You can assemble your fitness circuit however you want. Soft skin-friendly material, won't hurt your skin: Each part of the grass skirt strap is made of soft skin-friendly EVA foam material and wrapped with high-quality and durable PE plastic core. It weighs 1kg when assembled and has a diameter of 82cm, suitable for adults and teenagers. Beginners should not train for more than 15 minutes to avoid muscle soreness from overtraining. PORTABLE DESIGN & EASY TO INSTALL: The hula hoop consists of 6 removable foam parts, saving space and easier to store and carry. The hula hoop adopts a lightweight and strong buckle design, which is easy to install and remove. Therefore, you can install and use the gymnastics straps anywhere very quickly. 5 minutes of training = 1 hour of walking: Gym band training is a relatively high-intensity exercise. Spinning a hula hoop requires a lot of body movement, so your fitness hoop should only take 5 minutes to achieve the equivalent of 45-60 minutes worth of exercise. Regular exercise can enhance the coordination of the body and form charming curves and a healthy body. Package contents: 1 set of detachable hula hoops
