When pregnant, doing strength exercises like lifting weights is less likely to cause injuries than activities like jogging or running.

Some pregnant women did strength training during the middle and later parts of their pregnancy, and nothing bad happened — so it might be safe, but we don't know for sure yet.

When pregnant women do strength training, it's usually part of a mix of exercises, but most studies don't clearly say how hard, how often, or how much weight to use — so we can't figure out the best way to make moms healthier.

Doing strength exercises during pregnancy might lower the chances of getting high blood pressure or diabetes while pregnant, which could help moms stay healthier.

Doing strength exercises during pregnancy as part of a broader workout plan doesn't seem to lower the chances of needing a C-section, forceps, or tearing during birth—so the benefits are probably more about how your body uses energy than about making delivery easier physically.
