Best heart rate monitors 2025 — supercharge your training with heart rate data

Since the TICKR was discontinued, the Trackr has come in its place and got rid of the capital letters among other things. It's reliable, well-made and includes a rechargeable battery - which is a big improvement for heart rate monitors on the whole, and something we will hopefully see more of. 

It claims a 100 hour battery life, which for the average rider will probably last over two months of regular use. 

The only thing we would have liked to have seen is a USB-C charger rather than a proprietary cable, but otherwise, an excellent HRM with minimal outages. 

The Garmin HRM-Fit is specifically designed for women, and works by clipping directly onto a sports bra. There's no denying it's an expensive option - even double some of the non-specific HRMs on this list.

But, when paired with a Garmin device you do get some additional features like Heart Rate Variability, steps and intensity minutes - all things you get with a decent smartwatch, but with more accurate HR data. 

Our reviewer found it worked best with snug sports bras, and ideally not longline ones as it impacts the position of the sensor. 

Overall it can be far more comfortable than a traditional HRM strap as it's not being suffocated under your sports bra, but whether or not you think that's worth the asking price will be entirely up to you. 

The 4iiii Viiiiva Heart Rate Monitor has an extra useful function in that it acts as an ANT+ 'bridge', meaning it can send ANT+ data through to a Bluetooth device, so a traditional speed and cadence sensor can be used on an app on your phone, for instance. There are still some apps that don't currently support this multi-device connection, but this is more to do with them not being up to date rather than any fault of 4iiii's. 

Judging it just as a HRM, it performs very well according to our reviewer and was highly accurate compared to other devices. It is also simple to pair with cycle computers and phones, and the fit is good. It adjusts through two sliders at the back, keeping them off potentially angular parts of the body. At the front the strap connects to the unit itself through a popper on each side.

If you want to simply measure your heart rate then there are cheaper, options, but if you're looking for an HRM with better connectivity the 4iiii Viiiiva is a very solid option. 

Coospo's HW807 Heart Rate Monitor Armband is, as the name suggests, another HRM that you wear on your arm rather than the wrist or around your chest. The product images show the device being worn around the upper arm, but our reviewer found it worked just as well around the lower part of the forearm. 

Our reviewer also reported that the data the Coospo HW807 yields tracks very closely to that of a chest strap sensor, and it tracked very accurately compared to a number of other devices. A claimed 20-hour battery life, compatibility with most cycling computers and watches out there and quick, convenient recharging make the HW807 a very good buy for cyclists who prefer the armband-style HRM, so long as you're not planning to be switching kit mid-ride and are worried about your tan as we've already mentioned! 

The Hammerhead Heart Rate Monitor is a solid option if you don't need anything fancy, but want something that works time after time. 

The strap works somewhat differently to many other designs, in that the way you close it is by clasping both sections to the back of the chest-mounted pod. So no having to fiddle with clips or fasteners behind your back. 

It supports dual Bluetooth channels as well as ANT+ so it's compatible with everything from your smart phone to your smart trainer. 

At £49 it's not overly expensive, either. So if you're after a durable HRM, this could be the best choice.
