Made of environmentally friendly PP material, this ab roller withstands intensity exercise and can support up to 300 pounds without deformation. It is well suited for home workouts and core strength training. Advanced autorebound technology with a 50 pound thick silicone elastic cord provides a strong rebound force. This design helps engage muscles efficiently and is suitable for fitness beginners or experienced athletes. The flat panel design offers greater stability than a traditional AB roller. With an enlarged surface area for force distribution, it delivers smooth, controlled movement and reduces the risk of tipping and swaying. This ab board goes beyond the traditional ab roller with its versatility to meet the needs of a variety of exercises. Use scenarios Core rollout training at home: perform kneeling rollouts to build core and spinal stability, using controlled ranges of motion and gradually increasing difficulty as you get stronger. Progression from beginner to advanced: start with shorter ranges and lower resistance, then extend range and increase effort to match your improving strength, leveraging the autorebound tension for steady progress. Versatile workout tool: incorporate into stability and dynamic core routines beyond standard ab rollouts, such as moves that challenge balance and engage the obliques and supporting muscles.
