Detailed explanation-1: -A resting heart rate is the number of times your heart beats per minute when you’re not engaged in a physical activity. What’s normal depends on your age and activity level but, generally, a resting heart rate of 60 to 80 beats per minute (BPM) is considered to be in the normal range.

Detailed explanation-2: -In adults, a typical resting heart rate is 60–100 beats per minute, but structural or electrical disorders of the heart can cause it to rise or fall. Medications, a lack of sleep, and stress may also be factors. A person’s heart rate may be lower when they are sleeping or higher during exercise.

Detailed explanation-3: -The target heart rate, also known as THR, is based on 60 to 80 percent of a maximum heart rate. To figure your THR, use the table on this page. If you keep your heart rate in the lower range of the guideline, you will be able to exercise longer and have more weight loss benefits.

Detailed explanation-4: -A normal resting heart rate for adults ranges from 60 to 100 beats per 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 per minute.

Detailed explanation-5: -At rest, the normal heart beats approximately 60 to 100 times every minute, and it increases when you exercise. To ensure an adequate blood supply around your body, the four chambers of your heart have to pump regularly and in the right sequence.
