Vigorous intensity corresponds to what METs range?

• A. Light (<3 METs)
• B. Moderate (3-6 METs)
• C. Very vigorous (>9 METs)
• D. Vigorous (6-9 METs)

Answer: (D)

Metabolic equivalents (METs) quantify energy cost relative to resting energy expenditure; 1 MET is the energy used at rest. Exercise intensity is grouped by MET ranges: light is roughly below 3 METs, moderate spans about 3 to 6 METs, and vigorous begins around 6 METs and goes up to about 9 METs. This question asks where vigorous intensity falls, and the best answer places it in the 6–9 METs range. That aligns with common classifications, since activities that leave you significantly breathless or require substantial effort—like fast running or hard cycling—typically sit within this 6–9 METs window. The option describing very vigorous (>9 METs) sits higher than the standard vigorous label, thus it’s not the best match for the general vigor category. Light and moderate ranges lie below the vigorous threshold, so they don’t fit as well.
