What percentage of HRmax is considered moderate intensity exercise according to ACSM?

Moderate-intensity exercise is defined by the American College of Sports Medicine (ACSM) as activity that elicits a heart rate (HR) that falls between 64% and 76% of an individual's maximum heart rate (HRmax). This range allows for an adequate increase in cardiovascular fitness while ensuring that the exercise remains manageable and sustainable for most individuals.

For individuals who are new to exercise or those with certain health considerations, staying within this moderate range promotes health benefits without overexertion. Engaging in exercise at this intensity level is typically characterized by the ability to talk but not sing during the activity.

In this context, the option that corresponds with the established guidelines for moderate-intensity exercise is the range of 65-75% of HRmax. This distinction is important for both practitioners and exercise participants aiming for optimal health outcomes through physical activity.
