An activity with 5.5 METs would be classified as what intensity?

• A. Light
• B. Moderate
• C. Vigorous
• D. Very vigorous

Answer: (B)

METs quantify how hard the body works during activity, with categories used to guide exercise intensity. Light activity is under 3 METs, moderate is about 3 to 6 METs, and vigorous is above 6 METs. An activity at 5.5 METs falls in the moderate range because it costs more energy than light activity but does not reach the level of vigorous effort. In practical terms, you could still talk in full sentences while doing it, though you wouldn’t be able to sing. Examples of moderate-intensity activities include brisk walking, cycling on level terrain at a casual pace, or steady dancing.
