The video explains correct (abdominal) breathing and the correct positioning of the iPhone during a measurement with a chest strap (e.g. Polar H10). Phone upside down in the waistband with the display facing outwards. During the paced breathing sections let the phone move only from your belly. https://breathtuner.app/wp-content/uploads/2022/10/TwoBreathHrm.mp4
