It was originally defined as the product of training volume, measured in minutes, and training intensity, measured as average heart rate (beats per minute or bpm). For example, 50 min at 140 bpm TRIMP = 50 × 140 = 7000. One modified version of TRIMP splits training into zones related to the maximum heart rate (max HR) of the performer: zone 1 is at 50–59% maxHR; zone 2 at 60–69% max HR; zone 3 at 50–79% max HR; zone 4 at 80–90% HR; and zone 5 at 90–100% max...
