About the Redesign

If you visited this site prior to September 15th, 2018, you've no doubt noticed that I've since launched a complete redesign of the website.

If you're not happy with the new design, I sincerely apologize. I would have preferred to keep the old desktop design, but considering the majority of my site's users are now accessing the site from small-screen, touch-enabled, mobile devices, and considering Google is now penalizing websites for not being mobile/thumb friendly, I was left with no choice but to switch to a responsive, mobile-first design.

The good news is that now that I have combined the three separate versions of the site (mobile, desktop, and ad-free member) into a single design, this will free up a ton of my time for working to make the mobile-optimized calculators more desktop/laptop friendly. In fact, some of the redesigned calculators already offer a desktop-optimized form that becomes visible when you increase the width setting of the calculator (within the "Calculator Preferences" expandable panel).

Thank you in advance for your help and patience as I work to improve the redesign.

Heart Rate Calculator

This calculator is actually five heart rate calculators all rolled into one. Calculate your maximum (MHR), target (THR), and reserve (RHR) heart rates, plus calculate your resting heart rate health category and create a personal, printable heart rate training zone chart. The Notes tab includes:

  • How the calculator came to be.
  • Heart rate formulas.
  • How to check your heart rate, and a shortcut method.

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

Select male or female.

Avg RHR:Average RHR:Average resting heart rate (RHR):Average resting heart rate (RHR):

Average resting heart rate (RHR # beats per minute):

Before you get out of bed in the morning, and prior to any physical exertion, count the number of times your heart beats during a 1-minute time period. Repeat for several mornings and enter the average here. Note that you can feel your heart beat by placing your index and middle fingers on your neck, just to either side of your adams apple.

Intensity:Intensity level:Intensity level:Intensity level:

Intensity level:

Select your desired level of intensity. The percentages represent a target percentage of your maximum heart rate. Most resources I studied recommended target rates between 50% and 85% of your maximum -- hence the 65% default setting.

Include Heart Rate Training Zone Chart:

Move the slider to "Yes" position if you would like the results to include a custom training zone heart rate chart with the results. Note that the chart will be created using the Zoladz method of creating exercise zones.

Max rate:Maximum rate:Maximum heart rate (MHR):Maximum heart rate (MHR):

Maximum heart rate (MHR):

Based on your age and gender, and the MHR formulas listed under the Notes tab, this is your estimated maximum heart rate (MHR) in beats per minute (BPM). Note that another of many methods for calculating MHR is simply MHR = 220 - age. With so many MHR formulas available be sure to consult with a qualified medical physician to assist you with calculating your maximum heart rate.

Rate reserve:Rate reserve:Heart rate reserve (HRR):Heart rate reserve (HRR):

Heart rate reserve (HRR):

This is the difference between your calculated maximum heart rate and your resting heart rate.

Target (c):Target (classic):Target heart rate, classic method:Target heart rate, classic method:

Target heart rate, classic method:

Based on your entries, this is your target heart rate without factoring in your specific resting heart rate. The formula used by the heart rate calculator is THR = ((MHR - 70) * % intensity) + 70.

Target (K):Target (Karvonen):Target heart rate, Karvonen method:Target heart rate, Karvonen method:

Target heart rate, Karvonen method:

Based on your entries, this is your target heart rate after factoring in your resting heart rate. The Karvonen formula this result is based on is THR = ((MHR - RHR) * % intensity) + RHR;

Resting rtg:Resting rating:Resting heart rate rating:Resting heart rate rating:

Resting heart rate rating:

Based on your age, resting heart rate, and the charts located at http://en.wikipedia.org/wiki/Heart_rate, this is the category your average resting heart rate falls within. Note that if your age and/or resting heart rate fall outside of the chart, this field will display N/A.

If you would like to save the current entries to the secure database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.
