Your resting heart rate (RHR) is how often your heart beats in a minute, when you're not exercising and are completely relaxed. For a healthy adult, this is between 60 and 100 beats per minute.
Resting heart rates can differ from person to person. However, changes in your resting heart rate can be an indication of changes in your fitness level, stress level or physical condition. Active people often have a lower heart rate because their heart muscle is in better condition. It will take at least 24 hours of wearing the health watch to get your first resting heart rate measurement.
