Exercise Calculators

Target Heart Rate

Where should my heart rate be while exercising in order to reach my fitness goal?

Every one should know their maximum heart rate (MHR) for exercising safely, which depends on your age. Also enter your fitness goal and let this calculator help determine your target heart rate (THR).

Karvonen Target Heart Rate

Where should my heart rate be while exercising, based on my current fitness level and my fitness goal?

The Karvonen formula is a more personalized method to determine your exercise target heart rate. Enter your age, your resting heart rate, and the your intensity level during exercise and let this calculator help determine the target heart rate (THR) zone that will maximize the effectiveness of your cardio workouts.

Resting Heart Rate Average

Calculate my average resting heart rate for up to 5 days.

Resting heart rate is an indicator of your cardiovascular fitness level or how well your heart and lungs work. Typical resting heart rate is about 72 bpm, while highly trained runners may have resting heart rates around 35-40 bmp. Your average resting heart rate should be 15 to 20 bpm slower than your normal heart rate. The more fit you are, the lower your resting heart rate will be. As you monitor your average resting heart rate, you'll see this number drop as you become more fit.

Increased Life Expectancy

How much time have I added to my life expectancy based on my exercise habits?

According to Dr. Ralph Paffenbarger you increase your life expectancy by 2 hours for each hour of vigorous exercise. (Recent results of a study of over 17,000 Harvard alumni started in 1962.) Enter your exercise habits to calculate how many hours you have exercised or will exercise over time and the resulting increase in your life expectancy.
