The Polar H10 is a chest-strap heart-rate sensor for athletes who want consistent, responsive heart-rate data during running, cycling, gym sessions and structured training. Its electrical heart-rate measurement uses the supplied Polar Pro Strap, which combines soft fabric, silicone grip dots and a secure buckle to maintain contact as you move.

Bluetooth Low Energy, ANT+ and 5 kHz GymLink transmissions make the H10 useful across compatible sports watches, cycle computers, training apps and gym equipment. It can connect to two Bluetooth devices simultaneously and save one training session for later transfer. A user-replaceable CR2025 battery provides up to 400 hours of operation, while the WR30 rating allows use in water. Choose the correct Pro Strap size from the available Shopify variants.

Suggested Use & Compatibility

Moisten the Polar Pro Strap electrode areas, fasten it securely just below your chest muscles and attach the H10 connector before exercising. Pair through Polar Flow or your compatible watch, bike computer, fitness app or gym machine; the receiving device must support the relevant heart-rate protocol. Choose XS–S or M–XXL based on the live size options. Remove the connector and follow Polar's washing instructions for the textile strap after use. The H10 does not have its own display and a compatible app/device is required to see live readings.
