What is the maximum heart rate percentage for moderate-intensity exercise according to the ACSM guidelines?

The correct percentage for moderate-intensity exercise according to the American College of Sports Medicine (ACSM) guidelines is indeed 64-76% of maximum heart rate. This range is widely accepted in exercise physiology and represents a level of exertion that is sustainable for longer durations while still being effective for improving cardiovascular fitness.

Moderate-intensity exercise typically allows individuals to engage in activities that elevate their heart rate but still permit them to carry on a conversation. Exercising within this range has been associated with numerous health benefits, including improved cardiovascular health, weight management, and enhanced metabolic function. The defined range (64-76%) strikes a balance that maximizes these benefits while minimizing excessive strain on the body.

Understanding this classification helps individuals tailor their fitness programs effectively, ensuring they are exercising at an intensity that is both beneficial and safe for their fitness level.
