 Page 2 of 5 There are two different formulas you can use to calculate your Target Heart Rate: 1. The Maximal Heart Rate Formula is most commonly used to estimate Target Heart Rate because it’s easy to do and easy to remember. This formula does not take into account fitness level, medical conditions, or other things that might affect your heart rate. It is a good estimate but may be less accurate than other methods. How to Use the Maximal Heart Rate Formula Calculate your Max Heart Rate: (MHR = 220-age) Calculate your Max Heart Rate: (MHR = 220-age) Plug your numbers into the formula, using percentages that reflect your fitness level (i.e. 50% to 60% for beginners and 75% to 85% for advanced), as indicated below: Continued ›

• I do the exertion thing, I cannot hold a conversation though so I guess I am working too hard. I am out of breath most of the time while I am walking and especially when I get to go to the gym and use the elliptical or stair climber. I just know I have lost 21 pounds in about 4 months and still have close to 30 to go. - 4/19/2016 9:45:32 PM
• I can't use the target heart rate method either. I doubt my heart would handle it very well. I run out of breath long before I get there. I will do what I can do, and hope it is enough. I need to lose the weight, but am not willing to die trying. - 4/3/2016 11:00:11 PM
• Definitely cannot use the target heart rate method - my minimum would throw me into A-Fib if it got that high. I do use perceived rate of exertion and the talk test which both seem to work for me! Research all suggestions then listen to your body!! - 3/12/2016 8:58:28 AM
• Does this work for people who have a pacemaker/defibri
llator? I don 't believe my heart rate is allowed to go over 80. - 11/26/2015 11:10:43 PM

The chart on page 4 has an error. The order should be---
8. Very hard
9. Extremely hard
10. Maximum exertion

• I know some people like the definite quantification of having heart rate numbers, but individuals vary in this as in all other bodily measures. A friend's husband was getting extremely frustrated that he was not getting his heart rate up in his "target zone". He finally brought it up with his doctor, who told him that a lifetime of athletic activity had adapted his heart to have a larger than average stroke volume, which meant that his heart was very strong and efficient, pumping more blood per beat, and didn't need to be in the "target zone" to support vigorous activity. Numbers can be a guideline, but they are not the end-all and be-all. - 9/29/2015 11:18:57 AM
• The older you get, the more different the results of these two formulas are. Very confusing. - 9/29/2015 10:31:12 AM
• Great info! Thank you for the updated info !!! I've been using the numbers from 20 years ago!!!! - 9/8/2015 12:21:24 PM
• Good info! Thanks. - 9/5/2015 10:07:41 AM
• This was really excellent information, which really helps me a lot more than the general, often conflicting, info out there. Thanks too for the Target Heart Rate Calculator and link--that's really helpful! - 6/18/2015 5:41:16 PM

I think the the standard formula for determining MHR is very inaccurate for many people. I bought a heart rate monitor thinking I must not be working hard enough because I never saw improvement in my fitness level. According to the formula I should be in defib at rates over 160, but I found that I was frequently in the low to mid 160's and felt fine. When I slow down to the 75 to 80% range it feels like nothing more than a casual stroll. Although I am in better shape than many my age (60), I would hardly be considered an athlete, just a slightly overweight housewife. - 4/11/2015 10:05:09 AM
• "And what if you are walking 17 mph but it is all hills (up and down)"

That's some pretty fast walking!!!

My doctor told me to forget the calculations and heart monitor devices and let your body tell you (as long as you are pushing yourself).

and basically, you know when you are pushing yourself when " you can answer a question, but not comfortably carry on a conversation."

the most important thing here is I got my doctor's advice. - 2/24/2015 4:44:27 PM
• "Using this method, the goal is to work at a level where you can answer a question, but not comfortably carry on a conversation."
This should be printed on little laminated cards and affixed to every piece of exercise equipment at the gym, for the benefit of the chatty fatty workout buddies.
Quit your yapping and get to work!! - 2/24/2015 8:54:15 AM
