It depends on your gender, age, and physical conditioning. In general, a normal resting heart rate for an adult is between 70-80 beats per minute with women tending to have a slightly higher heart rate than men. Also children and the elderly tend to also have a higher rate that can be as high as 100 bpm.
The other factor is if you are physically fit. The more aerobic exercise you do the more your heart rate tends to be lower, even down to 60 bpm.
