What type of activity is considered moderate exercise?

Moderate exercise is defined as physical activity that raises your heart rate and breathing but still allows you to talk without strain. Walking briskly fits this definition perfectly, as it is a form of aerobic exercise that increases cardiovascular fitness without being overly strenuous. During a brisk walk, one can sustain a conversation while still experiencing an elevated heart rate, categorizing it as moderate exercise.

In contrast, running at a competitive pace typically qualifies as vigorous exercise because it substantially increases heart rate and may make it difficult to talk. Weightlifting can vary in intensity but is often considered resistance training rather than aerobic, making it less representative of moderate exercise. Yoga and stretching focus mainly on flexibility and balance, which do not engage the cardiovascular system to the same degree as moderate aerobic activities. Thus, brisk walking is the best choice as it embodies the characteristics of moderate intensity exercise.
