Experts agree. The heart is the most important muscle in the body and, like all muscles, must be exercised regularly to remain strong and efficient. How do you determine when you're exercising your heart safely and effectively? Fortunately, your heart provides the key information needed for determining the safety and effectiveness of your personal fitness program. Heart rate, which is reflected in a single number (beats per minute) provides a constant report on your body. How hard or easy you're exercising. How fast you're using energy. Too low a heart rate and your body reaps little or no benefits. Too high a heart rate and you'll tire too quickly and run the risk of frustration and injury. See more Heart Rate Monitors here! |
