Heart Rate

Your heart is constantly beating in order to supply oxygen and other nutrients throughout your body. When you exercise, you increase that demand for oxygen, so your heart beats faster. Your resting heart rate refers to your normal heart beat rate which is measured in beats per minute.  For teens between the ages of 11 and 17 (and for adults) a normal resting heart rate is 60-100 beats per minute.

Your maximum heart rate is calculated at 220 minus your age. As you exercise to maintain or increase cardiovascular health, you will want to obtain a heart rate that is 60-80% of your maximum heart rate. That range is referred to as your target heart rate. This is the range where you will be maintaining or increasing your endurance and heart health.

Quick: take your pulse…. To check your pulse you can place two fingers either on your wrist or neck (or anywhere else that your artery comes close to the surface of your skin, like the top of your foot or your groin!!!). Using a stop watch, count how many times your heart beats in a 30 second period, then double that number to get your beats per minute.

Post Question: What is your resting heart rate? Do 15 jumping jacks and measure it again… what was it then?
