What does working heart rate mean?

Working heart rate refers to the heart rate that an individual achieves during physical activity or exercise, reflecting the intensity of the workout. It is typically measured in beats per minute (bpm) and can help determine how hard the heart is working to supply oxygen to the muscles. Monitoring working heart rate can be useful for assessing fitness levels, optimizing training, and ensuring that individuals are exercising within their target heart rate zones for desired health benefits.
