Which activity is a classic example of aerobic exercise?

• A. Jogging for 30 minutes
• B. 15-second sprint intervals
• C. Heavy weightlifting with long rests
• D. Static stretching

Answer: (A)

Aerobic exercise is sustained, rhythmic activity that uses large muscle groups and keeps the heart rate elevated for an extended period, relying on oxygen to produce energy. Jogging for 30 minutes fits this perfectly because it stays at a steady, moderate pace, engages the legs continuously, and lasts long enough to keep the cardiovascular system working in the aerobic zone, which builds endurance.

The other activities don’t align with aerobic goals. A 15-second sprint relies on quick, high-intensity energy systems and can’t be sustained, so it’s more anaerobic. Heavy weightlifting with long rests emphasizes strength and short bursts of effort rather than continuous cardio. Static stretching targets flexibility and range of motion, not cardiovascular endurance.
