In the picture

1. 1Chest-strap sensor: measures heartbeats per minute from the ribs.
2. 2Wrist monitor: displays the current heart rate during movement.
3. 3Rising line segment: heart rate climbing as running effort increases.
4. 4Flat line segment: heart rate holding steady at a manageable effort.
5. 5Descending line segment: heart rate dropping during a cool-down walk.

Examples

• During a run, checking a watch to slow down before breathing becomes too hard.
• After a sprint, walking for a few minutes until the pulse returns closer to normal.
