【Industry-Leading Durability | 500kg Load Capacity】AYO's foam roller features a unique "solid integrated structure." The surface is made of high-density EVA material, which is durable, waterproof, and elastic, with protrusions that provide a sensation similar to acupressure massage. The combination of solid EVA material inside the stretch pole achieves twice the strength compared to conventional hollow types. It does not sag under body weight and is resistant to deformation even with long-term use, offering professional-grade durability. 【Authentic Fascia Release Effect】Simply place the fascia roller under your back and thighs and roll for 5-10 minutes daily on areas of concern to relax your fascia. The roller can be applied to areas where you feel stiffness or tension, such as the back, waist, shoulders, and neck, to loosen hardened fascia and relieve muscle soreness after training and everyday fatigue. It is also effective in alleviating chronic stiff shoulders and lower back pain caused by office work. 【3-Way Uneven Design for Beginners to Advanced Users】The surface has three types of uneven shapes: a flat shape like the palm of your hand, a tube shape like your fingers, and a protruding shape like your fingertips. The small protrusions like fingertips loosen stiffness, while the flat surface provides a gentle sensation like being pressed by the palm of your hand. You can start self-care at your own pace with your preferred level of stimulation. 【Lightweight and Portable | Storage Bag Included】The lightweight design makes it easy to carry to the gym. When placed in the included storage bag, it fits into the gaps in suitcases or gym bags. You can easily perform self-care anywhere, whether at home, in the office, at a yoga studio, gym, or on a business trip.
