Zone 2 Heart Rate Calculator for Women Over 40

Last reviewed: October 2026 by the Get Tips For Better Life Editorial Team

Zone 2 is the easy-but-steady effort where you can still talk in full sentences. It builds endurance and heart health without wearing you out, which makes it one of the best ways for women over 40 to exercise.

This free Zone 2 heart rate calculator gives your range by age, compares the main formulas side by side (including one made for women), and shows how many Zone 2 minutes to aim for each week. No sign-up, and nothing you enter is saved.

Zone 2 Heart Rate Calculator for Women

Find your Zone 2 heart rate range by age, compare the main formulas, and see how many Zone 2 minutes to aim for each week.

Please enter an age from 18 to 90. Resting heart rate should be 35 to 110, and max heart rate 120 to 220.

Zone 2 here means 60% to 70% of your max heart rate. If you add a resting heart rate, we also show the heart rate reserve (Karvonen) range. Formulas are estimates, and your real max can be 10 or more beats higher or lower. If you take a beta blocker or other heart medicine, heart rate targets may not apply to you: ask your doctor. Not medical advice.

Tanaka and Gulati columns are 60% to 70% of estimated max heart rate.

What Is Zone 2?

Heart rate training usually uses 5 zones. Zone 2 is the second-easiest: about 60% to 70% of your max heart rate. It feels easy to moderate. Your breathing is a bit deeper, but you can hold a conversation.

At this effort, your body gets a large share of its energy from fat, and you can keep going for a long time. Regular Zone 2 work builds your aerobic base, which helps your heart, stamina and daily energy.

Which Formula Should Women Use?

All of these formulas estimate your max heart rate. None of them measure it, and your real max can be 10 or more beats higher or lower.

  • Tanaka (208 minus 0.7 × age): based on data from thousands of adults. More accurate than 220 minus age for people over 40. This is our default and matches our heart rate zone calculator.
  • Gulati (206 minus 0.88 × age): developed from a study of over 5,000 women. It gives lower numbers than the other formulas.
  • 220 minus age: the classic, simple formula. It tends to be less accurate in older adults.
  • MAF (180 minus age): a popular endurance training method that gives a top limit for easy aerobic training. It’s not based on max heart rate and is often higher than the other ranges.
  • Heart rate reserve (Karvonen): if you enter your resting heart rate, we also show this range. Many fitness watches use it. It usually gives higher numbers.

If the formulas disagree, use the talk test to decide.

The Talk Test

You don’t need a watch to find Zone 2:

  • Zone 2: you can talk in full sentences, but you wouldn’t want to sing.
  • Too easy: you could sing.
  • Too hard: you can only say a few words at a time.

For many women over 40, a brisk walk, an easy bike ride, swimming or the elliptical at a steady pace is Zone 2.

How Much Zone 2 Do You Need?

The U.S. Physical Activity Guidelines recommend 150 to 300 minutes of moderate activity a week, plus muscle-strengthening on 2 or more days. Zone 2 counts toward the moderate minutes.

PlanZone 2 time each week
Starting out3 sessions of 20 to 30 minutes
Meets the guideline5 sessions of 30 minutes (150 minutes)
More endurance4 sessions of 45 to 60 minutes

Zone 2 After 40 and Menopause

Zone 2 is easy on joints, doesn’t leave you exhausted, and supports heart health, which matters more after menopause as heart disease risk rises. Pair it with strength training, because cardio alone doesn’t protect muscle and bone as well. Track your walks with the walking calorie calculator and the steps to miles calculator.

Safety Notes

  • If you take a beta blocker or other medicine that slows your heart rate, these targets may not apply to you. Ask your doctor for a target, or use the talk test.
  • Stop and get help if you have chest pain, pressure, dizziness or unusual shortness of breath.
  • If you’re new to exercise or have a heart condition, check with your doctor first.

Frequently Asked Questions

What is Zone 2 heart rate for a 50-year-old woman?
About 104 to 121 beats per minute using the Tanaka formula, or 97 to 113 using the Gulati formula for women.

What is Zone 2 heart rate for a 60-year-old woman?
About 100 to 116 beats per minute (Tanaka), or 92 to 107 (Gulati).

Is Zone 2 the same as the fat-burning zone?
Mostly, yes. Zone 2 is often called the fat-burning zone because your body uses a higher share of fat for fuel. But harder exercise burns more total calories per minute, so both have a place.

Why is my watch’s Zone 2 different?
Watches use different formulas. Many use heart rate reserve (with your resting heart rate), which gives higher numbers. Pick one method and use it consistently.

Is walking Zone 2?
For many women over 40, a brisk walk is Zone 2. Use the talk test or a heart rate monitor to check.

How long should a Zone 2 workout be?
Start with 20 to 30 minutes. As your fitness grows, 45 to 60 minutes is common. Aim for at least 150 minutes a week in total.

Can Zone 2 help with weight loss?
It helps you burn calories without leaving you too tired to stay active, but weight loss mostly depends on your overall calorie balance. See your numbers with the calorie deficit calculator.

What is the MAF heart rate?
It’s 180 minus your age, used as the top of easy aerobic training. For a 50-year-old, that’s 130 beats per minute.
