A normal resting heart rate for adults ranges from 60 to 100 beats a minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.To measure your heart rate, simply check your pulse. Place your index and third fingers on your neck to the side of your windpipe.or example, a well-trained athlete might have a normal resting heart rate closer to 40 beats a minute.

A. The normal resting adult heart beats regularly at an average rate of 60-100 times per minute. How fast the heart beats (heart rate) is governed by the speed of electrical signals originating from the pacemaker of the heart, the SA node..
