Final answer:
The U.S. Department of Health and Human Services recommends adults engage in 150 to 300 minutes of moderate-intensity, or 75 to 150 minutes of vigorous-intensity aerobic activity per week, and muscle-strengthening activities on 2 or more days per week.
Step-by-step explanation:
U.S. Department of Health and Human Services Physical Activity Guidelines
The U.S. Department of Health and Human Services (HHS) issued physical activity guidelines in 2008 and again in 2018 with some updates. These guidelines suggest that adults should:
- Move more and sit less throughout the day. Any amount of moderate-to-vigorous physical activity is beneficial.
- For significant health improvements, engage in 150 to 300 minutes of moderate-intensity aerobic activity per week, or 75 to 150 minutes of vigorous-intensity activity, or an equivalent mix of both.
- Spread aerobic activity evenly over the week.
- Include muscle-strengthening activities on 2 or more days per week as these have additional health benefits.
Moderate-intensity activities are those where you can talk but not sing, while vigorous-intensity activities are those where you can only say a few words without pausing for breath. Exceeding these recommendations can lead to more health benefits, especially for weight loss and maintenance.
