Which of the following activities is classified as a moderate intensity endurance activity?

Walking is classified as a moderate intensity endurance activity because it involves a continuous physical movement that elevates the heart rate to a moderate level while still allowing for conversation. It is a low-impact exercise that can usually be sustained for longer periods, making it accessible for a wide range of individuals, including those who may be new to exercise or are looking to maintain their fitness.

In contrast, jogging and running are generally associated with higher intensities; they raise the heart rate significantly more and demand greater effort from the cardiovascular system. Rowing can also vary in intensity, but it often combines both moderate and vigorous efforts depending on the pace and resistance level used. Hence, walking stands out as the most suitable choice for a moderate intensity endurance activity that can be included in daily fitness routines.
