Instructions:
In case of using a chest sensor, moisten the band (only the plastic part that is in contact with the skin).
Put on the sensor correctly:
Chest sensor (Rook Epic): you can place it a little bit more to the left since this allows a closer connection to the heart.
Arm Sensor (Rook Icon): The arm sensor should be placed on the left arm or forearm. To get even more precise metrics, place it over a vein and as tight as you can.
In case the training is on a mobile device, restart the phone.
