Prima Sole's Spring Hula Hoop (1.0kg). This weighted hula hoop helps you shape up effectively, tightening your waist and abdomen while naturally engaging your core. The textured surface stimulates the abdominal area. It features a soft spring structure with an internal spring and PVC soft material, absorbing impact and providing a gentle feel against the skin. The design has improved the issue of parts getting caught during rotation, and the noise level has been reduced compared to previous models. You can use it without worrying about disturbing others in apartments or condominiums. This model, produced by Japanese staff, offers a low price while simplifying the packaging. It stimulates the waist, back, and lower back, allowing you to train for as little as 10 minutes a day. #hulahoop #primasole #diet #quietsounddesign #weighted #springstructure #exercise #waisttraining #fitness
