Which configuration meets the minimum weekly MET-min target?

• A. 10 minutes of moderate-intensity activity per day, 7 days per week
• B. 60 minutes of vigorous-intensity activity 2 days per week
• C. 60 minutes of light-intensity activity 5 days per week
• D. 30 minutes of moderate-intensity activity per day, 5 days per week

Answer: (D)

Weekly MET-min targets measure energy expenditure as METs times minutes spent exercising in a week. The commonly cited minimum is about 600 MET-min per week.

The pattern of 30 minutes of moderate-intensity activity on five days gives 150 minutes per week. With moderate intensity around 4 METs, that’s 150 × 4 = 600 MET-min, hitting the minimum exactly and using a practical, sustainable weekly plan.

The other options don’t fit as neatly: the first option totals only 70 minutes of moderate activity (about 280 MET-min), which is below the target. The second option involves vigorous activity for 120 minutes in a week, which would exceed the minimum (usually well above 600 MET-min). The third option uses light intensity to reach 600 MET-min, but relies on longer time at a lighter pace. The configuration with moderate intensity over five days achieves the minimum cleanly.
