Typically, you’ll be able to anticipate round a yr of battery life from a Garmin chest strap like this. We’ve been utilizing our check unit for round 13 months and the battery degree continues to be displaying as ‘OK’ – so we’re on monitor there.
The one sore spot utilizing this chest strap is washing it – and we predict Garmin maybe didn’t go far sufficient with the design modifications right here.
In contrast to the Polar H10 (under), the battery compartment can’t be faraway from the strap and chucked into the washer. When you’re a frequent swimmer or want Polar’s apps to Garmin Join, it’s one to contemplate.
Nonetheless, we’ve used the HRM-Professional Plus on extra wet runs and sweaty Zwift periods than we are able to rely and have but to wash something aside from the sensors. There’s been no change of odor and no indicators of degradation.
This isn’t probably the most hygienic observe, and, to be clear, we’re unsure it will translate effectively to each consumer. A lot on Garmin boards and elsewhere complain about rapidly burning by means of their straps.
However, for us, the tight integration with its vary of sports activities watches – probably the most rounded and best-performing available on the market – and distinctive options like Operating Dynamics type evaluation are big. Bluetooth and ANT+ help additionally means it could possibly join with different units seamlessly.
For indoor runners, the HRM-Professional Plus can even monitor tempo and distance. When you take part in crew sports activities, it could possibly monitor further metrics like steps, depth minutes, and all-day coronary heart fee information, too. It’s a fantastic all-rounder.
Polar H10
Key issues

- Sensor tech: ECG
- Connectivity: Twin-band ANT+ / Bluetooth
- Telephone compatibility: iOS and Android
When you’re an exerciser who cares about accuracy, the Polar H10 chest strap is one other gold-standard, super-reliable choice primarily based on our testing.
The iOS and Android-friendly strap boasts Bluetooth and ANT+, so you’ll be able to pair it to a bunch of units and third-party apps – together with even Garmin sports activities watches, if you happen to like.
It additionally introduces a modified design (and a loftier worth) over its predecessor, the Polar H9, including silicon friction dots to assist preserve the strap in place. Plus, we’ve discovered it’s a bit extra snug to put on.
As talked about above, the battery compartment can be eliminated, that means the strap will be included in washer cycles. This makes it a fantastic choice for these prone to get it moist by way of sweat or swimming.
We’ve used it many instances in opposition to the most recent health trackers and smartwatches which have landed at Wareable HQ, primarily throwing information into Strava and the Polar Beat app, which is constructed for coronary heart rate-based coaching.
It’s nonetheless a chest strap we return to and may confidently say delivers the products.
Apple Watch Sequence 10
Key issues

We’ve put the most recent mannequin by means of the identical rigorous testing in exercises. And, like its predecessors and its Apple Watch Extremely 2 and Apple Watch SE siblings, it persistently proves to be probably the most correct optical coronary heart fee sensors on check.
By way of last figures and latency, it performs effectively alongside devoted sports activities watches – even throughout the likes of interval coaching. Although, naturally, bear in mind it received’t provide the similar real-time reliability as a chest strap.
Information is viewable inside Apple’s Exercise app, however the good thing about having a robust assortment of third-party apps means you can too view that information in locations like Strava and Runkeeper.
Carrying the Sequence 10 helps flood Apple Well being with information, too. Coronary heart fee variability, VO2 Max, resting coronary heart fee, and strolling common HR can all be seen as tendencies throughout the final day, week, month, or yr, and this information can be exported to a PDF to be shared with medical professionals.
There’s much more, as effectively. The system’s ECG App harnesses {the electrical} coronary heart fee sensor within the Digital Crown to take electrocardiograms and verify for coronary heart points like atrial fibrillation, and the temperature sensor works along side the optical coronary heart sensor to supply cycle monitoring for ladies.
It’s an excellent all-rounder that’s pretty much as good for these acutely aware of their coronary heart well being as it’s for these critical about monitoring train.
Garmin Fenix 8
Key issues
- Physique place: Wrist
- Sensors: Optical, ECG, SpO2
- Exterior HR monitor pairing: Sure
- Telephone compatibility: iOS and Android
All of Garmin’s watches provide broadly stable coronary heart fee monitoring accuracy, although the Fenix 8’s huge array of options and new-gen Elevate Gen 5 sensor ensures it barely edges these siblings.
It doesn’t provide the very best mix of options, affordability, and design for most individuals – that’s reserved for one thing just like the Forerunner 265 – however the accuracy is pretty much as good as we’ve ever examined in a sports activities watch.
It is available in three dimension choices (42mm, 47mm, and 51mm), and, throughout over 100 checks in opposition to different watches and a chest strap, it’s probably the most persistently in keeping with the latter.
We nonetheless suppose Garmin’s Elevate expertise (throughout the board) has a really slight tendency to overreport most coronary heart fee figures throughout exercises, however the truth stays that the Fenix 8 (and the Fenix 7 Professional, Epix Professional, and Venu 3 – the one different Garmin units with the most recent Elevate sensor) is on the peak of monitoring from the wrist.
You even have the choice to pair up an exterior HR sensor if you happen to’re not fairly glad with the extent of accuracy on provide. That optical HR accuracy is essential outdoors of tracked train, too, because it powers quite a lot of helpful insights. Runners and cyclists can profit from Garmin’s in-depth and intuitive metrics probably the most, although issues are getting higher for swimming (with the Fenix 8 additionally together with new dive smarts) and different sports activities.
HRV Standing is among the most useful, supplying you with an at-a-glance view into your coronary heart fee variability tendencies with loads of context. But, this solely scratches the floor of how coronary heart fee information feeds into Garmin Join.
Additionally current are the likes of resting coronary heart fee, Physique Battery, VO2 Max, Coaching Standing, stress monitoring, calorie burn, respiration monitoring, sleep monitoring, and extra.
It’s complete, making the Fenix 8 a fantastic decide for many who need the highest training-focused coronary heart fee monitoring expertise.

Each 41/45mm variations use the identical multi-path optical coronary heart sensor that was retooled for the Pixel Watch 2, but, regardless of Google’s claims of improved accuracy, we discovered it carried out very equally to that last-gen watch in our testing.
That’s no dangerous factor, although – it was already among the many greatest for responding to modifications in coronary heart fee and performing equally to a chest strap, and that’s not modified for the Pixel Watch 3,
We’ve been impressed every time we’ve examined it, and the Fitbit monitoring expertise has been bolstered for the third-gen watch to incorporate important metrics for critical trainers, Cardio Load and Each day Readiness.
They’ve been added to an already complete coronary heart monitoring bundle: coronary heart fee variability, resting coronary heart fee, ECG, physique responses (stress monitoring), sleeping coronary heart fee, and way more that debuted with the unique.
The Pixel Watch 3 nonetheless doesn’t get near one thing like a Garmin in coaching and extra sports activities insights. But, the stellar coronary heart options make it a prime wellness system – and that accuracy ensures it locations as the very best for Android customers who need dependable data.
The one draw back from a coronary heart monitoring perspective is that you simply’ll must subscribe to Fitbit Premium to get probably the most out of it, even when components just like the Each day Readiness Rating have now appeared from behind this paywall.
Whoop Strap 4.0
Key issues
- Physique place: Wrist, bicep, varied Whoop Physique areas
- Sensor: Optical

The Whoop 4.0 is probably the most versatile coronary heart fee monitor available on the market.
Designed to reside in your wrist by default, the Whoop Physique vary of clothes additionally permits it to be worn on the hip by securing it within the waistband of shorts, the ribs by way of a sports activities bra, or the higher arm by means of a devoted sleeve. New collections are additionally being added on a regular basis – that means you’re not restricted in placement right here.
After testing completely different Whoop Physique clothes and completely different straps over the previous few years, we’ve discovered the corporate’s bicep band helped present the very best accuracy. The standard wrist place proves fairly inconsistent in any exercise monitoring, so preserve the potential further value of straps or Whoop Physique clothes in thoughts if you happen to prioritize tip-top accuracy.
Elsewhere, the truth that there’s no show implies that sporting Whoop 4.0 is sort of at all times unobtrusive – and means you’ll be able to put on a watch (or smartwatch) on the opposite wrist with out wanting like an excessive amount of of a sq..
The tracker additionally provides weekly and month-to-month studies in your health, restoration, sleep, and well being – and there’s a superb Well being Monitor, which makes use of a visitors gentle system to maintain tabs in your respiratory fee, resting coronary heart fee, and physique temperature, to warn you when one thing is out of whack.

There are downsides, although. Whoop depends closely on coronary heart fee accuracy to energy its total platform, focusing primarily on restoration, exercise pressure, and sleep. And if this information has a nasty day – and it very a lot can if you happen to monitor solely from the wrist – it skews the entire image.
The one different main factor to notice is the price. Regardless of Whoop decreasing costs final yr, it’s nonetheless costly.

Selecting a coronary heart fee monitor: What to contemplate
As we alluded to earlier, understanding what you need from a coronary heart fee monitor is paramount when discovering the very best match in your wants.
Chest strap vs. coronary heart fee monitor watch
Whether or not you select a chest strap or a watch to measure your coronary heart fee is a case of accuracy vs. practicality.
Chest straps are mainly designed to assist exercisers who need probably the most correct readings. As we clarify in our picks under, one of these coronary heart fee monitor can reply extra rapidly to your coronary heart fee’s modifications than the optical sensors present in watch and health tracker displays.
Whereas the latency and accuracy in watches are sometimes weaker than a chest strap, they provide superior consolation, comfort, and options. These units are designed to observe you all day and are available filled with options different than simply easy BPM monitoring for exercises.
Coronary heart fee accuracy in watches
Whenever you begin ramping up the depth – performing rounds of useful health actions or interval coaching throughout working or biking – optical sensors in health trackers or watches battle to deal with the speedy rises and falls in coronary heart fee.
Typically, the averaged-out information received’t be too removed from a chest strap in the very best choices (seen under), however you’ll nonetheless face latency points in real-time.
They can be flummoxed by the motion of the wrist throughout workout routines – ones reminiscent of press-ups, burpees, or Olympic lifting – because the pores and skin contracts and tightens, making it more durable for the sensor to do its job.
Darkish pores and skin and tattoos can even have an effect on accuracy, as pores and skin tone can have an effect on the sunshine reflection. Sadly, not sufficient work has been accomplished throughout the board to beat accuracy points due to ethnicity, so, you probably have darkish pores and skin and need the easiest information out of your exercises, we suggest a chest strap for exercises.
However, chest straps use electrocardiogram (EKG) sensors which might be extra correct and – given their place near your coronary heart – extra aware of rises and falls. The regular place in your chest makes the info much less noisy.
Varieties of information that coronary heart fee trackers can seize
A coronary heart fee monitor will monitor your BPM throughout exercises, and that information must be correct if you happen to’re utilizing it to coach inside zones. A small discrepancy might have you ever coaching within the unsuitable zone, and this could negatively have an effect on your coaching.
Nonetheless, the standard of research of that information after your exercise (reminiscent of VO2 Max estimates) is all the way down to the platform you’re utilizing to trace your exercise.
However coronary heart fee displays will be helpful outdoors of the fitness center. They are going to monitor your bpm 24/7, and analyze resting coronary heart fee, readiness, sleep, and stress. So, selecting a extra generic system that may provide a extra rounded have a look at your well being can be interesting.
Bear in mind which you could double up
The good thing about ANT+ and Bluetooth expertise (current in some units) means you may get the very best of each worlds if accuracy is your prime precedence.
For instance, we use a sports activities watch’s optical coronary heart fee sensor for many actions as a result of its versatility and ease of use. If we’re within the fitness center lifting weights, or just hopping on the bike for a fast warm-up or warm-down spin, the accuracy is greater than ok.
Nonetheless, the place wrist-based choices usually battle – reminiscent of within the swimming pool or working exercises the place we need to preserve a constant eye on our HR – we as a substitute join a chest strap to our watch.
