Final answer:
The HHS recommends 150 to 300 minutes of moderate aerobic activity per week or 75 to 150 minutes of vigorous-intensity activity, equating to 30-60 minutes daily, with muscle-strengthening two days a week. Even starting with 10-15 minutes of moderate activity daily is beneficial. The correct option is 4.
Step-by-step explanation:
The amount of exercise you need daily to be healthy varies depending on your fitness goals, health status, age, and other factors.
The U.S. Department of Health and Human Services (HHS) recommends at least 150 minutes (2 hours and 30 minutes) to 300 minutes (5 hours) per week of moderate-intensity aerobic activity, or 75 minutes (1 hour and 15 minutes) to 150 minutes (2 hours and 30 minutes) per week of vigorous-intensity aerobic physical activity, or an equivalent combination of both.
This equates to about 30 to 60 minutes daily. In addition, muscle-strengthening activities should be done on 2 or more days per week. Even a moderate exercise program of about 1 hour per day can bring substantial health benefits.
However, it's important to start with what you can manage; even 10 to 15 minutes of moderate activity each day is beneficial. Gradually build up to the recommended amount of 30 minutes per day, five days a week.
Remember that any physical activity is better than none and that it's crucial to avoid an all-or-nothing point of view. The correct option is 4.
