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.
Your resting heart rate should be between 60-100 beats per minute. If you are an athlete or train a lot, your resting heart rate could be lower. That is an average. Resting heart rate above 150 is tachycardia (fast).During exercise, you should shoot for between 40-60% of your heart rate max which is generally estimated by subtracting your age from 220.Example a 20 year old (220-20=200) would have a max heart rate of 200. You should be careful when starting exercise not to get your heart rate too close to max.For athletes-or people who often perform cardiovascular activity  - a normal resting heart rate may be closer to 40 beats a minute.      If your your heart rate is continuously above 120 bpm or below 40  bpm you should consult a doctor.
