What is a .hrm file?
File Extension Details
The HRM file extension is a data format primarily associated with Polar Electro heart rate monitors and their legacy training software, such as Polar ProTrain. This file type is used to store detailed physiological and performance metrics recorded during an athletic training session or exercise. An HRM file is typically structured as a plain text file containing several sections, including a header that defines the exercise parameters—such as date, time, duration, and recording interval—and a data block that lists the actual recorded values. These values often include heart rate in beats per minute, speed, cadence, altitude, and power output, depending on the sensors used during the workout. Because the format is text-based, it allows for relatively easy parsing by third-party fitness analysis software. While modern fitness devices have largely transitioned to more flexible formats like FIT or TCX, the HRM format remains a significant legacy standard for professional athletes and researchers who utilize historical data or specific analytical tools like GoldenCheetah to monitor long-term training loads and physiological adaptations.
