Garmin’s next-gen heart rate monitor adds expanded running dynamics, activity recording and more



OLATHE, Kan./May 15, 2025 – Garmin (NYSE: GRMN) today announced the HRM 600 – a premium heart rate monitor that gives athletes new performance data and ways to help improve their training. The monitor provides accurate heart rate readings, while also tracking heart rate variability (HRV), and sends that information to compatible Garmin smartwatches, cycling computers and apps – allowing users to see their training data in real time. New features like added running dynamics1, activity recording without a watch and a rechargeable battery can help athletes take their training to the next level, while two new strap sizes can help them find their most ideal fit.


What’s new with HRM 600

  • Expanded running dynamics: The new step speed loss feature tells runners with the newly released Forerunner 970 how much they slow down when their foot hits the ground. Runners can also improve their form with existing running dynamics like stride length, vertical oscillation and ground contact time balance – all of which are available with select smartwatches, like the new Forerunner 570.

  • Activity recording: From team sports like basketball and soccer, to activities when a smartwatch can’t be worn, record workout data – including heart rate, calories, speed, distance and more – and view it afterwards in the Garmin Connect app.

  • Rechargeable battery: Get up to 2 months of battery life with every charge.

  • Functional design: With the press of a button, easily wake and pair the heart rate monitor. Plus, the LED light will indicate when it’s awake, when the battery is running low and more.

Other top features

  • Connectivity: Transmit real-time heart rate and HRV data to compatible Garmin smartwatches, Edge cycling computers and fitness equipment – plus apps like Garmin Connect and the Tacx Training app.

  • Activity tracking: Track steps, calories burned, heart rate, intensity minutes and more without a smartwatch, then sync to Garmin Connect to update all compatible Garmin devices.

  • Training versatility: The monitor sends pace and distance data from indoor track and treadmill runs to compatible smartwatches2 – along with heart rate data captured during swimming activities.

  • Comfortable fit: The easily adjustable strap comes in two new sizes (XS-S and M-XL) to fit a range of body types. For added convenience, the module is removable and the strap is machine washable.
