In relation to exercise, what does the heart rate monitor track?

The heart rate monitor is specifically designed to track the heart rate during different intensities of exercise. This measurable data allows individuals to monitor how their heart responds to varying levels of physical demand, providing insights into their cardiovascular fitness and helping to tailor workout intensity for optimal performance and safety.

In addition to measuring real-time heart rate during exercise, this functionality aids in understanding training zones, such as fat-burning or aerobic zones, which can enhance the efficacy of workouts. By monitoring these fluctuations, users can also gauge their recovery rates and overall fitness progression over time. Other options, such as tracking average resting heart rate or maximum achievable heart rate, are not the primary functions of a heart rate monitor during exercise sessions, as they focus more on static or absolute metrics rather than the dynamic changes that occur during physical activity. Furthermore, counting steps is outside the scope of what a heart rate monitor does, as that function is more aligned with pedometers or fitness trackers.
