At what intensity are moderate-intensity physical activities typically performed?

Moderate-intensity physical activities are generally performed at 40 to 60% of maximum heart rate. This range allows individuals to engage in activities that elevate their heart rates enough to be beneficial for cardiovascular health while still being manageable for most people. At this intensity, individuals can typically talk but not sing during the activity, indicating a level of exertion that is effective for improving fitness and overall health without being excessively challenging.

Higher intensities, such as 60 to 80% of maximum heart rate, fall into the vigorous-intensity category, where the exertion level becomes significantly higher, making it harder to maintain the activity for long durations. Likewise, lower intensities below 40% may not provide sufficient stimulus for improving health outcomes. Thus, the delineation between moderate and vigorous intensity is crucial for setting appropriate exercise guidelines based on individual fitness levels and health goals.
