Estimate resting, maximum, and exercise heart rate ranges based on age, resting heart rate, and training intensity. This free heart rate calculator shows target heart rate zones and workout ranges in a clean calculator layout.
Basic method:
Uses a simple estimate of maximum heart rate from the formula 220 minus age.
Karvonen method:
Uses heart rate reserve, which includes both maximum heart rate and resting heart rate.
Target range:
The calculator applies workout intensity percentages to estimate training ranges.
Zone planning:
It also shows broader training zones for easier workout planning.
Heart rate zones can help make workouts more structured by showing easier and harder effort ranges. Many people use them for cardio training, conditioning, endurance work, and recovery sessions.
They can be especially helpful when you want a simple way to control workout intensity.
Your result shows your estimated maximum heart rate, target training rate, and broader heart rate zones. This gives you both a quick workout target and a wider training guide.
Many people use the moderate ranges most often for steady cardio and general fitness work.
Resting heart rate can vary a lot, but many adults fall somewhere around 60 to 100 beats per minute.
Maximum heart rate is an estimated upper limit of how fast your heart may beat during intense effort.
The Karvonen method uses heart rate reserve, which takes resting heart rate into account when calculating training targets.
No. They are useful estimates and can differ from person to person.
