How to check your heart rate:
Find your radial pulse.
Use two fingers.
Not your thumb.
Place just below wrist crease at base of the thumb.
Press lightly until you feel a pulse.
Count beats for fifteen seconds, multiply times 4. Fifteen seconds times 4 equals rate.
Or count beats for thirty seconds, multiply times 2. Thirty seconds times 2 equals rate.
Save to your health log.
