Question

which of the following would be the best target heart rate for a person wanting a good aerobic workout program?
○ 40–50%
○ 70–85%
○ 55–65%
○ 90+%

Explanation:

For an aerobic workout, the target heart rate zone that promotes cardiovascular fitness and effective aerobic benefits is typically 70–85% of the maximum heart rate. The 40–50% range is too low (more of a warm - up or very light activity), 55–65% is in the moderate - light to moderate range (not the best for a good aerobic workout), and 90 + % is too high (entering anaerobic or very high - intensity territory which is not ideal for a standard aerobic workout).

Answer:

70–85%
