Polar claims the H10 is probably the most correct in the marketplace – correct to +/- one millisecond – due to a 3rd electrode and silicone grippers to maintain it in place. In over two years of testing, I have not had a single concern so can’t refute these claims, and our knowledgeable reviewer had no complaints both. With that stated, given most different chest straps right here have carried out equally nicely, I would not purchase the H10 for that motive alone.
The motive I’d purchase it’s the super-simple adjustment and very comfy, safe match.

The pod itself can’t be faraway from the strap, which suggests washing must be accomplished by hand, relatively than by the washer, and Garmin suggests you do this after seven exercises or after each pool swim.

It has related options to the HRM-Pro Plus, however can’t be worn swimming, and it appears unfair to ask ladies to pay extra for much less tech.
The subsequent is the Wahoo Tickr Fit. This is a fore-arm primarily based optical coronary heart price sensor that is an excellent possibility for individuals who do not need to put on a full chest strap. If you might have a smartwatch with a coronary heart price monitor inbuilt, then that is most likely the optimum answer, however when you discover chest straps uncomfortable or restrictive, then this is able to be our decide. Another possibility right here although is the simply-titled Coros Heart Rate Monitor. This too is worn on the forearm, prices the identical and gives very related performance. The Coros guarantees an extended life between fees, whereas the Tickr Fit boasts ANT+ connectivity and a spare strap.
How to decide on a coronary heart price monitor

While each programs depend on bodily contact to assemble their readings, optical sensors are typically utilized in arm- or wrist-based programs the place the variance could be seen.
One drawback with that is {that a} smartwatch is never worn as tightly as an elasticated chest strap and as such optical programs are typically extra liable to points over tough terrain or when operating, as bumps can briefly break the all-important contact between pores and skin and sensor.
In easy phrases, the most effective factor for measuring your coronary heart price will virtually all the time be a chest strap, however when you’re interested by normal traits and day-to-day coronary heart well being too, a wrist-based optical system will seemingly be extra up your avenue for its consolation, comfort, and the onboard laptop that can course of the info relatively than counting on being paired to a cellphone or bike laptop.
If you need to run a hybrid system, smartwatches will usually have the power to watch your coronary heart price independently utilizing the optical sensor on the again, in addition to pair with a devoted HRM strap for extra correct in-sport measurements.

Below, I’ve rounded up a few of the extra frequent questions in an effort to allow you to make your determination.
Should I take advantage of a coronary heart price monitor or an influence meter for biking?
Heart price is usually a rider’s first introduction to structured coaching – maybe past ‘perceived effort’ or a hill and a stopwatch – and it ought to all the time stay a key a part of the image, regardless of the quantity, depth or sort of coaching an athlete is enterprise.
Within the context of biking efficiency, the most effective coronary heart price displays are commonly overshadowed by the most effective energy meters.

What do the waterproof rankings imply?
IPX7, IP67, 5ATM? Can somebody please make sense of this?
Waterproof rankings are a posh mixture of numbers and letters that want a little bit of decoding earlier than you’ll be able to perceive their that means. Luckily, it is fairly simple to do.
IP rankings stand for Ingress Protection, and the 2 subsequent digits symbolize safety towards solids and liquids respectively. The first digit, representing safety towards solids like mud and dust is a ranking between 0 and 6. The bigger the quantity, the higher the safety, whereas an X means it hasn’t been examined. The second digit, representing safety towards liquid ingress – ie water – is a ranking between 0 and eight, and once more, the larger the quantity the higher.
ATM rankings focus solely on waterproof strain ranking. They are most simply outlined by multiplying the quantity by 10, to get the depth at which your machine can deal with strain. For instance, a tool with a 5ATM ranking can maintain pressures equal to what you’d discover in water at a depth of fifty metres.
How usually ought to I wash a coronary heart price monitor?
When contemplating chest strap coronary heart price displays, in case you are significantly sweaty then be sure you get one thing that’s simply washed. The management unit of most chest straps pops off, and preserving it clear will prevent from salt corrosion. Most gadgets suggest being hand washed after every use, after which a visit by the washer after round seven makes use of. However, because the management unit on Garmin’s HRM-Pro is fastened, this wants hand washing every time. Of course, it goes with out saying that completely different guidelines apply to smartwatches.
What is the most effective coronary heart price monitor for Zwift?
For the essential funciton of monitoring your coronary heart price, this frequent query is definitely answered with ‘any of them,’ since they’re all technically Zwift appropriate. However, past connectivity, there are some issues that make some higher than others for Zwift and the world of indoor biking basically.
As touched on above, chest-based coronary heart price displays are normally extra correct than optical wrist-based displays, so when you’re after accuracy, make certain any coronary heart price monitor you employ in Zwift is chest-based.
Next, driving on any of the most effective good trainers is all the time a sweaty affair, even when you set your self up in a freezer, and as such corrosion resistance is a extra pertinent concern than for driving open air.
Furthermore, Zwift and different indoor biking apps can require a mess of sensors transmitting concurrently. While all are appropriate, when you’re operating a very complicated knowledge setup then be sure you go for one thing with each Bluetooth and ANT+ to assist keep away from undesirable interference points.
Our decide as the most effective coronary heart price monitor for Zwift is the 4iiii, as a result of alongside being safe, comfy and correct (in my testing), it may possibly additionally act as a Bluetooth bridge in your energy meter or your good coach. This means as a substitute of connecting a number of gadgets to your laptop computer, probably reaching your restrict or inflicting interference, you’ll be able to ship all the info in a single stream, lowering the prospect for dropouts.
Does measurement or weight matter in coronary heart price displays?
Sure, the scale and weight of one thing you are going to want to hold in your wrist or your chest is necessary. You clearly do not desire a 3kg home brick strapped to your chest while you are attempting to run or trip. However, the rationale we have not talked about it in our information or product suggestions above is that the variations are so small that it isn’t price evaluating.
A coronary heart price strap that weighs 19g vs one other at 21g will not be noticeable, nor will one which’s 8mm thick in comparison with one other at 10mm. Metrics that make extra sense to match are issues like battery life, ease of adjustability and the way securely and comfortably they keep in place when worn.
What is HRV?
HRV stands for Heart Rate Variability, however what does it imply? It’s a typical false impression that your coronary heart beats at a wonderfully common tempo, and by that, I imply in case your coronary heart is thrashing at 60bpm, it is not beating precisely as soon as per second. According to Stephanie Shell, a Senior Physiologist specialising in restoration on the Australian Institute of Sport, the time between every beat may differ by between round 20 and 200 milliseconds.
HRV, or Heart Rate Variability, is the measurement of the irregularity in these intervals. We have an in depth deep dive explaining what’s HRV, however the primary overview is that that is immediately tied to our physique’s autonomic nervous system, and {that a} bigger HRV quantity (in comparison with our personal baseline) is an effective indication of being well-recovered and able to tackle extra coaching stress.
What do the adjustability rankings on this information imply?
In every of the product suggestions above, I’ve rated how simply the center price strap could be adjusted. Many will solely want adjusting each few weeks as they loosen or undergo the wash, but when a coronary heart price monitor is complicated to regulate, it may possibly usually result in it being too tight or too free. You can wager that the one time you discover it is barely too free is if you’re already halfway by a trip, and you do not need to must strip your layers off to have the ability to modify it to forestall it from slipping down and changing into a belt.
As a part of my testing, I frolicked becoming and adjusting every of the straps in flip, making notes to match how simply it may very well be accomplished, whether or not it may very well be accomplished one-handed, or whether or not it baffled me greater than attempting to free a pair of tangled headphones.
How will we take a look at the most effective coronary heart price displays?
Our testing for this information to the most effective coronary heart price displays has been an ongoing course of for nearly three years. Each take a look at begins with an unboxing, throughout which we make a remark of the packaging for its eco-friendliness. All manufacturers use some type of plastic of their packaging, however I normally discover Wahoo is the most effective on this regard.
For chest straps, I then learn the care directions and make a remark of washing suggestions, earlier than eradicating the battery cowl in a trial run battery swap, noting the problem. Next up comes the adjustment, and understanding how simple – or tough – it’s to suit the strap. On the chest straps, Garmin’s HRM Pro Plus wins this, with shut second-places coming to each Polar choices, though the benefit of becoming the HRM-Fit onto the understrap of a sports activities bra is one thing our ladies testers have applauded too.
Next, I analysis the claimed options and qualities of every coronary heart price monitor and check out these options throughout testing to verify they do what they need to, and to expertise how stated characteristic may profit a consumer’s exercise.
In the absence of getting a health care provider with an ECG machine available for all of my exercises, I improvised a technique to verify correct readings. Throughout testing, I spend a time sporting three (generally 4) coronary heart price displays for my exercises – two chest straps and one or two wrist straps – relying on what I’m testing.
This compares the readings for every coronary heart price monitor towards no less than two others and lets me weed out any gadgets with inaccurate knowledge or poor connectivity. As is broadly accepted, the chest straps carried out finest right here, whereas optical wrist sensors tended to battle to maintain up with fast adjustments up or down, particularly when operating or mountain biking, as this shakes the wrists greater than indoor biking.
It’s honest to say not one of the chest straps carried out particularly badly on this regard, and when sufficiently tight, the optical models are fairly good too, so the primary differentiator in accuracy was truly how usually they dropped connection. This is an issue I often skilled with Wahoo’s older entry-level Tickr, however the Trackr has been nice because it launched in 2024. It was a specific drawback with low cost coronary heart price displays purchased on Amazon, and therefore why none of them are featured right here.
I then set all of them to the identical size earlier than sporting them individually to notice consolation and the way securely they keep in place. Thankfully all coronary heart price displays I’ve examined have been comfy sufficient that they’re simply forgotten as soon as in place, however I do discover the Polar H10 is most comfy and safe.
