Final answer:
Health experts advise young adults to do about 30 minutes daily of moderate-intensity aerobic exercise or 150 to 300 minutes of vigorous-intensity activity to achieve health benefits like improved cardiovascular health and increased lifespan.
Step-by-step explanation:
Health experts recommend that young adults engage in at least 150 to 300 minutes per week of moderate-intensity aerobic exercise, which translates to about 30 minutes per day on average if spread throughout the week. Alternatively, vigorous-intensity exercise is recommended at 75 to 150 minutes per week, which can be met with about 15 to 30 minutes per day of activity like running or playing basketball. The benefits of meeting these exercise recommendations include maintaining a healthy weight, stronger immune system, better joint mobility, improved cognitive functions, and overall psychological well-being. For young adults pursuing an endurance program, they may engage in 1 to 3 hours per day of moderate to high-intensity exercise.
The U.S. Department of Health and Human Services (HHS) and the American Heart Association encourage people to move more and sit less, emphasizing that some exercise is better than none. Starting with even ten to fifteen minutes of moderate activity each day and gradually increasing it can bring health benefits and should be encouraged. To maximize cardiovascular health, engaging in 60 minutes of vigorous aerobic activity per day is particularly effective.
