Special Pops: Pregnancy — which ExRx describes the recommended prescription?

• A. ExRx: 3 days per week, moderate VO2 40-60%, RPE 12-14; 15-30 minutes of aerobic activity.
• B. ExRx: Daily vigorous activity; 60 minutes.
• C. ExRx: 1 day per week, light activity; 10 minutes.
• D. ExRx: 5 days per week, high VO2; 20 minutes.

Answer: (A)

During pregnancy, staying active at a moderate intensity on most days is recommended, with sessions long enough to be beneficial but not overly strenuous. The prescription shown fits that approach: aerobic exercise three times a week at a moderate intensity—about 40–60% of VO2 or a perceived exertion of 12–14—with sessions lasting 15–30 minutes. This provides a regular, manageable stimulus that supports health and fetal well-being without stepping into vigorous effort, which is generally discouraged in uncomplicated pregnancies. The frequency and duration strike a balance between consistency and safety, helping maintain fitness and reduce common pregnancy discomfort. Patterns that call for daily vigorous activity, only one short session per week, or five days of high-intensity workouts tend to be too demanding or insufficient for gradual, safe adaptation.
