Question

Quizplus · Accepted Answer

The intensity of a physical activity is the amount of effort expended by the individual. It is usually measured in terms of heart rate, perceived exertion, or the amount of weight lifted. Factors such as the duration and frequency of the training session may affect the overall effectiveness of the workout, but they are not indicative of the intensity of the exercise itself.
