Heart rate zone

How it is used

Used in endurance training, cardio classes, and sports science. Athletes aim to stay in, enter, or avoid a certain heart rate zone during sessions.

Example sentences

1. During the long run, I stayed in a lower heart rate zone so I could build endurance without fading late.

   Here, heart rate zone marks a target intensity range, helping the runner control effort across the entire session.

2. The bike workout felt easy, but my watch showed I had drifted into a higher heart rate zone on every climb.

   In this sentence, the term is used as feedback from monitoring data rather than from subjective feeling alone.
