Polar has launched its new H9 heart rate chest strap, for those stepping up their training for in 2020.

The Polar H9 joins the existing H10 and OH1+, offering ANT+, Bluetooth and 5KHz connectivity, so it will pair to pretty much all running watches, phones and even smartwatches. The Polar H9 is $59.99, so it undercuts the $89.99 Polar H10 chest strap nicely.

ANT+ is pretty widely used in the fitness world, so you might find your gym equipment pairs to it as well.

The biggest omission here is a lack of on-board storage, so you can’t head to the hills for a run without your phone and upload the workout when you get back. If you want that, you’ll need to buy the beefier H10 instead.

Of course, Polar wants you to use the Polar Beat app which shows real time heart rate and lets you set targets for heart rate zones. There’s also audio feedback as you workout – and analysis when you’re done.

There’s the Polar Flow app, which is the company’s workout tracker, and naturally you can pair the H9 into that via Bluetooth.

There’s heart rate built into pretty much every wrist wearable now – but some users may still be looking for better accuracy for heart rate tracking.

While you can generally trust the heart rate data from your running watch when you’re out for a steady jog, if you’re doing HIIT sessions then that data is going to be junk. That’s where people stepping up in training often start looking for chest straps.

Using a chest strap during a HIIT session can help you check that you pushed adequately and get a better idea about how your body is recovering.

Garmin running watches will only work out your threshold heart rate zones if you use a chest strap for your session.

That’s why the Polar H9 looks like a great option. There’s a bunch of decent features available via the Polar app – and an inviting price point of $59.99. The battery will last a year if you do an hour of working out per day, so there’s minimal charging required.
