Which description best matches the Type of exercise for cardiorespiratory training?

• A. Strength training with free weights
• B. Aerobic exercise performed in a continuous or intermittent manner that involves major muscle groups
• C. Flexibility exercises only
• D. Balance training

Answer: (B)

Cardiorespiratory training revolves around aerobic activity that keeps the heart rate elevated over time by using large muscle groups. The description that fits this best is aerobic exercise performed in a steady or interval fashion and involving major muscle groups, because it directly targets the heart and lungs to improve endurance and overall aerobic fitness.

This means activities like brisk walking, running, cycling, or swimming—whether done continuously or in intervals—are the primary way to develop cardiorespiratory endurance. In contrast, lifting free weights focuses on muscular strength and size, flexibility-only work doesn't elevate heart rate enough to train the heart and lungs, and balance training targets stability and coordination rather than aerobic capacity.
