915 Generation Wrist Force Device Electronic Health Ring Timing Speed Trai

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.
