This multi-functional abdominal wheel roller is designed for muscle workouts, especially core strengthening and planks. Featuring a 290mm widened four-wheel stable structure, it increases ground contact area to ensure safety during use. The rubber-coated hubs with wear-resistant textures prevent slipping, reduce noise, and minimise damage to the floor. The auto-rebound function assists in exerting force while reducing pressure on the back and joints, making it highly suitable for fitness beginners. The upgraded four-elbow support design distributes elbow pressure and enhances elbow comfort. Whether you are a fitness beginner or an experienced athlete, it offers customisable workout options to suit the needs of everyone.
