> Strength training, including lifting weights, is generally supported during pregnancy with appropriate modifications to support your changing body and avoid certain techniques.

For many expecting parents, the question of whether to continue or start lifting weights during pregnancy is a common one, and the good news is that strength training is generally encouraged with thoughtful adjustments. The American College of Obstetricians and Gynecologists (ACOG) supports strength training during pregnancy, recognizing its significant benefits. These can include improved posture, a reduction in common back pain, and even support for a smoother recovery post-birth. It's about finding a rhythm that supports your changing body, rather than pushing limits.

The key to safe weightlifting in pregnancy lies in modification and awareness. It's wise to avoid heavy one-rep maximum lifts and any Valsalva maneuver, which involves holding your breath during exertion. Instead, consider increasing your repetitions with lower weights, focusing on controlled movements. As your pregnancy progresses, especially after 20 weeks, it becomes important to avoid exercises that require you to lie flat on your back (supine position). This is because the growing uterus can put pressure on a major blood vessel. Opt for inclined benches or seated positions for upper body work.

The general guidance is to continue with the strength training you were doing before pregnancy, adjusting as needed. If you weren't regularly lifting heavy weights pre-pregnancy, now isn't the time to start a new, intense heavy lifting regimen. Instead, focus on maintaining activity levels with lighter weights and proper form, much like how you might approach understanding [Are probiotics safe during pregnancy?](/pregnancy/can-i/take-probiotic-pregnant) — by building on existing habits and focusing on gentle support.
