Which type of exercise is considered moderate-intensity?

Walking briskly is considered moderate-intensity exercise because it generally elevates the heart rate and increases breathing but allows an individual to still carry on a conversation. This form of activity is typically performed at a level where the individual feels somewhat out of breath but can sustain the effort for an extended period.

In contrast, sprinting is characterized by high-intensity effort that places significant demands on the cardiovascular system, often leaving one breathless and unable to speak comfortably. Powerlifting focuses on maximal strength and typically involves short bursts of high effort followed by rest, rather than sustained activity. Yoga can vary in intensity, but many forms focus more on flexibility and can be considered low-intensity compared to brisk walking, especially when looking at cardiovascular demands.

Therefore, brisk walking aligns with the definition of moderate-intensity exercise, as it strikes a balance between effort and sustainability.
