How to Manually Check Your Heart Rate. A normal resting heart rate for most adults is between 60 and 100 beats per minute. Conditioned athletes typically have resting heart rates closer to 60 beats per minute.

You want to stay between 50 percent to 85 percent of your maximum heart rate. This range is your target heart rate.
