Which statement about body positions is correct after 12 weeks of pregnancy?

• A. Avoid prone or supine positions after 12 weeks of pregnancy
• B. Plyometrics are always recommended in the second trimester
• C. Avoid all forms of stretching
• D. Remain in a supine position for all exercises

Answer: (A)

As pregnancy progresses, the growing uterus can press on major blood vessels if you lie flat on the back or face down. After about the first trimester, lying supine (on the back) or prone (on the stomach) can reduce blood return to the heart and decrease blood flow to the fetus, sometimes causing dizziness or faintness in the mother. The safest approach for exercise and daily activity is to avoid full supine or prone positions and use side-lying, seated, or semi-reclined positions with support.

So, the best guidance is to avoid prone or supine positions after 12 weeks and choose positions that keep the mother and fetus safer and more comfortable. Plyometrics aren’t universally recommended in the second trimester, stretching isn’t prohibited when done properly, and remaining in a supine position for all exercises is not appropriate after this stage.
