KYTO Multifunctional Wrist Force Device New Electronic Health Ring Centrifugal Ball Unisex Hand Trainer Timing Speed Trainer 

              The intelligent core fitness ring can display the real-time speed of exercise duration and exercise strength    

Summary Mode, Time Mode, Power Mode    

The core rotates with the wrist and uses the principle of 3D acceleration sensing to record the movement duration and movement force    

If you are strong, it will strengthen the centrifugal resistance principle of centrifugal force. When the speed is greater, the inertia generated is greater, and greater force control is required, thereby driving the body muscles to move.    

Anti-slip handle: The curved handle fits the wrist and can be held firmly even under strong vibration
