When is the best time to measure resting heart rate?

First thing in the morning, before you get out of bed and before any caffeine, food, or activity. After a night's sleep your body is in its most rested state, giving you the cleanest, most repeatable baseline. Caffeine, food, movement, and stress all temporarily raise your heart rate, so later readings tend to be inflated.

How do I measure my resting heart rate manually?

While at rest, place your index and middle fingers on the inside of your wrist or the side of your neck (not your thumb), find a steady pulse, and count the beats for a full 60 seconds. Repeat on a couple of mornings and average the results for a reliable baseline.

What is a normal resting heart rate?

For most healthy adults, a normal resting heart rate is between 60 and 100 bpm. Well-trained endurance athletes are often lower — sometimes in the 40s — because a fitter heart pumps more blood per beat and doesn't need to beat as often.

Why is a lower resting heart rate usually better?

A lower resting heart rate generally indicates a more efficient heart and better cardiovascular fitness, because the heart pumps more blood per beat. As your fitness improves with training, your resting heart rate typically falls over time.

Is a wearable or manual count more accurate for resting heart rate?

Both work well for tracking trends. Wearables calculate resting heart rate from your lowest sustained overnight readings, which removes human counting error and gives a clean baseline. A manual morning count is free and reliable too. The most important thing is to use the same method consistently so your numbers stay comparable.

How does resting heart rate help with training zones?

Your resting heart rate is a key input for the heart-rate reserve (Karvonen) method, which sets training zones based on the gap between your resting and maximum heart rate. This makes your zones far more personal than age-based shortcuts. Use the Max Heart Rate Calculator first, then the Heart Rate Training Zone Calculator with your resting heart rate.

How to Measure Your Resting Heart Rate (And Why It Matters)

Your resting heart rate (RHR) is one of the simplest, most useful numbers you can track for your health and fitness. It's free, it takes about a minute, and it gives you a genuine window into how your heart, your fitness, and even your recovery are tracking over time.

It's also the foundation for getting the most out of heart-rate training. If you want to train in the right zones, you'll need an accurate resting heart rate to plug into the maths. We'll point you to the right tools for that below, but first, let's get your number, and get it properly.

What Is Resting Heart Rate?

Your resting heart rate is the number of times your heart beats per minute (bpm) while you're completely at rest: relaxed, awake, and not recently active, stressed, or stimulated. It reflects how hard your heart has to work to keep you ticking over when there are no demands placed on it.

For most healthy adults, a normal resting heart rate sits between 60 and 100 bpm, according to the American Heart Association. Well-trained endurance athletes often sit considerably lower (sometimes in the 40s) because a fitter heart pumps more blood per beat and simply doesn't need to beat as often.

As a general rule, a lower resting heart rate tends to indicate more efficient heart function and better cardiovascular fitness. Over time, watching your own RHR trend downward is one of the clearest signs your training is working.

Why Resting Heart Rate Is Worth Tracking

Beyond being a fitness marker, your resting heart rate is genuinely useful for a few reasons:

It tracks your fitness over time. As your cardiovascular fitness improves, your RHR typically falls. It's a satisfying, objective sign of progress.
It flags overtraining and illness. A resting heart rate that's notably higher than your normal baseline can be an early signal that you're under-recovered, fighting something off, dehydrated, or stressed.
It powers accurate heart-rate training. The most accurate way to set training zones, the Karvonen, or heart-rate reserve, method, uses your resting heart rate directly. Get this number right, and your zones get a lot more personal.
It's a broad health indicator. A persistently elevated resting heart rate has been associated with higher cardiovascular risk in large population studies, which is why it's worth knowing your baseline.

When Should You Measure Your Resting Heart Rate?

Timing is everything here. If you're measuring manually, the single best time is first thing in the morning, before you get out of bed, ideally before you've even checked your phone.

Why the morning? After a night's sleep, your body is in its most genuinely rested state. You haven't eaten, moved, caffeinated, or absorbed any of the day's stresses yet. Caffeine, food, physical activity, stress, nicotine, and even standing up all temporarily raise your heart rate, so measuring later in the day gives you a number inflated by whatever you've done in the hours before. The early-morning reading strips all of that away and gives you the cleanest, most repeatable baseline.

For the most reliable result, take your reading at roughly the same time each morning, and avoid measuring immediately after an alarm jolts you awake or after a particularly broken night's sleep, as both can nudge the number up. Consistency matters more than any single reading; what you're really after is your typical, repeatable baseline.

How to Measure Your Resting Heart Rate Manually

You don't need any equipment; just two fingers, a clock or phone with a seconds counter, and a quiet minute. Here's the method:

Stay still and relaxed. Do this before getting out of bed in the morning, or after sitting calmly for at least five to ten minutes.
Find your pulse. Place your index and middle fingers (not your thumb, it has its own faint pulse that can throw off the count) on the inside of your wrist, just below the base of your thumb. Alternatively, press gently on the side of your neck, just beside your windpipe.
Count the beats. Once you feel a steady pulse, count the beats for a full 60 seconds. Counting for the whole minute is more accurate than counting for 15 seconds and multiplying by four, which can magnify small errors.
Repeat and average. Take the reading on two or three consecutive mornings and average them for a baseline you can trust.

Press firmly enough to feel the pulse clearly, but not so hard that you compress the artery and distort it. If you lose count, just start again; there's no rush.

Using a Wearable or Fitness Tracker

Smartwatches and fitness trackers (like Apple Watch, Garmin, Fitbit, Whoop, and Oura) make this even easier, often reporting your resting heart rate automatically. Most devices calculate it from your lowest sustained readings overnight, which is arguably an even cleaner baseline than a single morning manual count.

Wrist-based optical sensors are convenient and good enough for tracking trends, though they can be slightly less precise than a chest-strap monitor during exercise. For simply tracking your resting baseline over time, a wearable is more than adequate, and the automatic overnight reading removes the human error of manual counting entirely. Whichever method you choose, the key is to stick with it so your numbers stay comparable.

What Affects Your Resting Heart Rate?

It's normal for your resting heart rate to vary a little day to day. Several factors can push it up or down, including:

Fitness level: fitter people generally have lower resting heart rates
Age, body size, and genetics
Caffeine, nicotine, and some medications
Stress, anxiety, and poor or short sleep
Illness, dehydration, and hot weather
Recent exercise or physical activity
Air temperature and body position (lying, sitting, or standing)

This is exactly why standardising your measurement, same time, same conditions, at rest, matters so much. A one-off high reading isn't cause for alarm; a sustained shift away from your normal baseline is what's worth paying attention to.

When to See a Doctor

Resting heart rate is a useful signal, not a diagnosis. See your GP if your resting heart rate is consistently above 100 bpm (tachycardia) or below 60 bpm without being a trained athlete (bradycardia), especially if it comes with dizziness, breathlessness, chest discomfort, fainting, or an irregular, fluttering pulse. If anything feels wrong, get it checked; this article is general information, not medical advice.

Turn Your Resting Heart Rate Into Better Training

Once you've got an accurate resting heart rate, you can use it to train smarter rather than just harder. Your RHR is a key ingredient in calculating personalised heart-rate training zones using the heart-rate reserve (Karvonen) method, which is far more individual than generic age-based shortcuts.

To build your zones, you'll also need your maximum heart rate, and we'd strongly suggest skipping the outdated '220 minus age' rule in favour of a more evidence-based estimate. Start with our Max Heart Rate Calculator to get that number first, then plug your resting heart rate into the Heart Rate Training Zone Calculator to find the exact zones for fat burning, endurance, and high-intensity work.

And if you'd rather have an expert build the whole plan around your numbers, a great coach will take the guesswork out of it entirely. Browse Sydney personal trainers by suburb or get matched with a trainer who can put your heart-rate data to work.
