Title: A title for these calculator results that will help you identify it if you have printed out several versions of the calculator.

Age: Your current age.

Fitness Goal: Choose the fitness goal closest to your actual goal.

Output Fields

Target Heart Rate (THR): Exercise at an intensity that will keep your heart rate within this range to best meet your fitness goal.

Max Heart Rate (MHR): Based on your age, this is your maximum heart rate. Even during high intensity exercise you should not let your heart rate go above this number.

Beats Per Minute (bpm): The number of heart beats per minute (bpm). If your exercise equipment has a pulse sensor it will be expressed as beats per minute.

Beats in 10 Secs: Find your pulse at your neck or wrist. Using a clock or watch with a second hand, count each heart beat for 10 seconds. (This number times 6 will be your heart beats per minute (bpm).)

Exercise Intensity Table: Your fitness goal helps determine the intensity of your exercise. In turn, exercise intensity and your age determines your target heart rate range to meet your fitness goal. This table shows the exercise intensity and target heart rate range for each fitness goal.

  1. I get on treadmill walk at elevation 3 and speed 3.5 for 30 minutes and my heart rate stays around 70-78 I’m 63 and weigh 274, 6ft tall I recently put weight on due to and accident I had and was layed up in bed for 7 months ,broke 6 ribs and collar bone and scapula with collapsed lungs, and the ribs are healed and the scapula the collar bone has had 2 operations with a bone graft and metal plate

  2. Last year I had an upper left lobectomy. My upper left lung portion was removed due to cancer. This year I want to get in shape again. Exercise has always been a part of my life. I am wanting to use the Fat Burn setting on the treadmill however; my doctor is not an exercise advocate. I am on blood pressure medication and find myself scared to go to my heart target: even the minimum. I am 70 years old and in good condition, I think. Have been exercising with a trainer since February 2014.

  3. We just got treadmill for Christmas. For over all good health… But do not want to over due heart rate … At times its 134 … But not for long then down to the 80’s and 70’s… I’m 140 pounds 5′.4″
