Which activity NOT listed as an example of developing cardiovascular endurance?

• A. Running
• B. Walking
• C. Rowing
• D. Swimming

Answer: (C)

Cardiovascular endurance comes from sustained rhythmic activity that keeps the heart rate elevated for an extended period and uses large muscle groups. Running, walking, and swimming all fit this pattern well because they are continuous, steady activities that you can perform for several minutes to longer while maintaining an aerobic pace. Rowing, while it can be performed at a steady aerobic pace and does train the heart and lungs, is often treated as a full‑body exercise that combines cardiovascular effort with significant resistance and technique work. Because of that, some curricula categorize it more as muscular endurance or total-body conditioning rather than as a pure cardiovascular endurance activity. In that context, rowing is not listed as an example of developing cardiovascular endurance, making it the selected option.
