Which percentage range defines the Moderate target heart rate zone?

• A. 55-70%
• B. 36-54%
• C. 71-90%
• D. <35%

Answer: (A)

Moderate intensity sits between light and vigorous effort. In target heart rate terms, it’s about 55 to 70 percent of your estimated maximum heart rate. This range keeps you working hard enough to improve fitness but not so hard that talking becomes nearly impossible. If you estimate max HR with 220 minus age, you’d aim for roughly 55–70% of that number. For example, at age 30, max HR is about 190 bpm, so the moderate range would be roughly 105–133 bpm. Ranges lower than this are light, while ranges higher than this are vigorous, so 55–70% best matches moderate intensity.
