Final answer:
Pregnant and postpartum women are recommended to engage in at least 150 minutes of moderate-intensity aerobic exercise spread throughout the week.
Step-by-step explanation:
The aerobic exercise recommendations for pregnant and postpartum women vary depending on individual health conditions. However, the American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women with no contraindications engage in at least 150 minutes of moderate-intensity aerobic exercise spread throughout the week. This can include activities such as brisk walking, swimming, stationary cycling, or low-impact aerobics. Postpartum women can also follow similar recommendations, gradually increasing exercise intensity and duration as they recover.
