About the Polar H10
Optical heart rate sensors measure blood flow through the skin using LED light — comfortable, but prone to lag during rapid heart rate changes like sprints and intervals. The Polar H10 uses ECG electrical sensing instead, the same fundamental technology used in medical heart monitoring, reading the heart’s electrical signals directly through chest contact. This is why the H10 is so frequently chosen as the reference device in scientific studies that validate other heart rate monitors.

What size Polar H10 strap should I buy?
Measure around your chest, just below the pectoral muscles. XS–S fits a 23–26” chest, and M–XXL fits a 26–34” chest. If your measurement falls on the 26-inch overlap, choose based on your preferred fit — the strap is adjustable within each size range. The soft strap is 71% polyester and 29% spandex and is washable after removing the sensor module.
Does the Polar H10 work with Garmin, Apple Watch, Peloton, and Strava?
Yes. The H10 broadcasts standard heart rate over Bluetooth and ANT+, so it pairs with Polar, Garmin, Apple, and Suunto watches and apps including Polar Beat, Strava, Nike Run Club, and Peloton. Its 5 kHz GymLink signal also connects to many older treadmills and gym machines. You can run a Bluetooth and an ANT+ connection at the same time, plus two Bluetooth connections simultaneously.
Can the Polar H10 record heart rate without a watch?
Yes. The H10 has internal memory for one training session. Start a session in the Polar Beat app, leave your phone behind, and the strap records heart rate data, then syncs to Polar Beat when you reconnect. This is handy for swimming, contact sports, or any workout where carrying a phone or wearing a watch is impractical. The H10 records heart rate only — it does not capture running dynamics or GPS pace and distance.
Is the Polar H10 waterproof for swimming?
Yes. The Polar H10 is fully waterproof, rated to 30 meters (WR30), and can be worn while swimming. Because Bluetooth and ANT+ signals do not travel through water, live heart rate is not transmitted while submerged; instead the H10 stores the data and syncs it afterward, or pairs with a compatible Polar swim watch that supports GymLink HR. Wear the strap snugly for best results.
How long does the battery last and is it replaceable?
