How many hours a week is recommended for aerobic exercise as per the guidelines?

The recommendation of 3 or more hours of aerobic exercise each week aligns with the guidelines established by health organizations like the American Heart Association and the Centers for Disease Control and Prevention. These bodies emphasize that adults should aim for at least 150 minutes of moderate-intensity aerobic activity, or 75 minutes of vigorous-intensity activity, each week.

When translated into hours, this makes it clear that engaging in aerobic exercise for at least 2.5 hours (or 150 minutes) leads to around 3 hours or more when factoring in a balanced approach to exercise throughout the week. This level of activity is associated with significant health benefits, including improved cardiovascular health, weight management, and a decrease in the risk of chronic diseases.

It's important to note that while the recommendation for daily activity can support the cumulative hours, the overall guideline points towards engaging in aerobic activity consistently over the course of the week to maximize health outcomes. The other choices do not meet these established recommendations effectively.
