Does the subject want to ask, "What if the fitness circle can't be sensed by climbing?" Check the sensor and adjust the position.

1. Check the sensor: Check whether the sensor of the fitness circle works normally. If the sensor fails or is damaged, you can contact the manufacturer or after-sales service center for repair or replacement.

2. Adjust the position: Make sure the position of the fitness ring is correct. If the fitness ring is not placed correctly, the sensor will not work properly. Adjust the position of the fitness ring to make it contact with the body more closely.
