Best Heart Rate Monitors of 2026

A year on a single coin cell is the detail that makes the HRM 200 easy to live with. There's no charging cradle to lose, no cable rattling around a kit bag, and no half-hour window before a ride when you discover the pod is flat. You wet the electrodes, clip the pod onto the strap, and it's broadcasting. When the year is up, the replacement is a drawer job rather than a purchase.

We kept coming back to it because it asks nothing of you. The strap is machine washable, the pod unclips, and the 3 ATM rating covers sweat and rain without a second thought. Through our sessions the trace stayed steady on easy miles and moved the way it should when we lifted the pace. Two strap sizes, XS–S and M–XL, make a snug fit easier to find than a single band does, and a loose strap is the usual reason a monitor gets blamed for bad readings.

It also carries heart rate variability, which matters more than it sounds, because HRV is what most recovery and training-load apps actually want and this strap feeds it without extra hardware. The thing to check before ordering is the rest of your setup: the HRM 200 is built around Garmin watches, bike computers and apps, so if you train on a Wahoo computer or a Polar watch, confirm it pairs with yours first. For everyone else it does the core job without drama, which is why it's the one we point to first.

If a chest strap is the reason you stopped tracking your heart rate, the COROS band is the fix. It wraps a soft fabric band around your upper arm and it's light enough that you forget it's there: no ribcage strap, no electrodes to wet, nothing to adjust mid-run.

It's optical, and that's the trade. An armband sits where the artery is close to the skin and the band doesn't move the way a wrist does, so steady running and tempo work read well. The very short, very hard efforts — 30-second intervals, a heavy set — are where any optical sensor lags a chest strap, and we noticed the gap in the first seconds of an interval rather than in the middle of one.

The practical design is thoughtful: the sensor pops out so you can wash the band, it pairs with up to three devices at once, and the battery is rechargeable with a rated 38 hours. Two things keep it out of the top spot. The app is the weakest link in the chain, and sessions can connect without passing heart rate data until you re-seat the band. And this is a workout tool rather than an all-day tracker, so don't buy it expecting a full day of readings.

Both radios for very little money is the H6's pitch, and it delivers: Bluetooth 4.0 and ANT+ on the same strap, so a phone app and a watch or bike computer can listen at once. The strap is a wide, soft cloth band with a pod that unclips for washing, the battery is rated 300 hours, and IP67 means sweat, rain and a rinse under the tap aren't a problem.

We liked it most as a second monitor: the one that lives in the gym bag, the one a new rider borrows, the spare you don't mind losing. In our sessions it paired quickly with a phone and a watch, and the numbers landed close to what a far dearer chest strap showed at the same effort. Comfort is the surprise at this end of the market, with a wide band that stays put without digging in.

Where it gives ground is consistency under pressure. Readings that look rock steady in an easy session can wander when you go deep into an interval, and starting a workout sometimes means re-pairing before anything shows up. Buy it as a value pick with a spare battery in the bag, not as the monitor you'll still be wearing in five years.

The LEDs are why we reach for this one: a light confirms the pod is awake, paired and charged before you start, so you're not staring at a blank heart rate field in the first interval wondering which end is broken. Plenty of straps leave you guessing. The TRACKR doesn't, and it does it with a rechargeable pod rated for up to 200 hours instead of a coin cell you have to remember to buy.

It's slim and soft on a 30-gram pod, and it stayed comfortable through long sessions. Readings held up through steady riding in our sessions, and swapping the strap for a wash is a one-second job. The thing to get right before ordering is the strap itself, which comes in a single size and runs snug at the top of its range; a broad chest is the case where this one stops working, so measure before you buy, because the strap decides it.

Eight hundred hours is the number the HS500 leads with, and it isn't marketing arithmetic: that's a CR2032 lasting a couple of years at an hour a day, four days a week. Add IP67, ANT+ and Bluetooth, and a wake-up time under a second, and you have the cheapest credible chest strap in this group.

What we found is that it's at its best when you're not asking much of it. Cruising on the bike or the rower, the readings held; push into a hard effort and they got jumpy, which is exactly the moment you want the number to be right. The flashing LED is a small kindness, since you can see at a glance that it's awake without opening an app. Setup instructions are thin, so budget twenty minutes to work out which app sees it and how. Treat it as a second monitor — one for the gym bag, one left attached to the rower — rather than the strap you build a training block around, and it earns its keep.
