How many minutes per day should most adults accumulate of moderate-intensity cardio to meet guidelines?

• A. 60-90 minutes per day
• B. 15-30 minutes per day
• C. 30-60 minutes per day
• D. 90-120 minutes per day

Answer: (C)

The main idea is the weekly guideline for moderate‑intensity cardio: about 150 minutes per week. That translates to roughly 30 minutes on most days, making it practical to accumulate cardio in daily goals.

Choosing 30–60 minutes per day fits this well because it aligns with a common daily target (about 30 minutes on most days) and still allows for longer workouts on some days. This ensures you meet or exceed the weekly minimum without requiring excessive daily time.

Shorter daily targets, like 15–30 minutes, risk not reaching 150 minutes per week if not done consistently. Longer daily targets, such as 60–90 or 90–120 minutes, are not necessary to meet guidelines and can be harder to maintain for many people, even though they still meet the requirement if achieved.
