What are the baseline physical activity guidelines for adults?

• A. At least 150 minutes of moderate activity or 75 minutes of vigorous activity per week, plus two days of strength training.
• B. Only 60 minutes per week.
• C. Daily 5 hours of intense training.
• D. No guidelines exist.

Answer: (A)

The main idea being tested is what adults should aim for each week to stay healthy, balancing cardio with strength work. The recommended baseline is at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity spread through the week, plus strength training on two or more days. This combination gives both cardiovascular benefits and muscle/bone health, supporting weight management and overall fitness.

Why this fits best: 150 minutes of moderate activity provides substantial aerobic benefits without needing extreme daily effort, and adding two days of strength training helps maintain muscle mass and bone density, which is important as you age. It’s a practical, achievable target that most health organizations endorse.

Why the other options don’t fit: 60 minutes per week is far below the recommended amount and wouldn’t yield the same health benefits; daily five hours of intense training is excessive for most adults and isn’t considered the baseline; and there are established guidelines, so saying no guidelines exist is inaccurate.
