For secondary-aged students (11–18 years), how often should moderate to vigorous cardiovascular activities be performed weekly?

• A. One to two days per week
• B. Three to seven days per week
• C. Every day with sessions over 60 minutes
• D. Only on weekends

Answer: (B)

Regular cardiovascular activity for teens is best when it happens on most days of the week. Doing moderate to vigorous cardio three to seven days weekly gives the heart and lungs consistent training, helps form a lasting habit, and supports ongoing fitness gains instead of concentrating effort only on weekends or a couple of days. It also allows for rest days as needed, aiding recovery and keeping motivation high. The other options either miss most days or push an unrealistic routine (like daily sessions longer than an hour) or restrict activity to weekends, which wouldn’t provide steady cardiovascular improvement. So aiming to be active most days—three to seven days per week—is the most effective and practical frequency.
