Can you workout during your first trimester of pregnancy?

Yes: And throughout your pregnancy. The only time you should avoid it is in the third trimester, and only then if it is aggravating your back or other pains.

Always ask OB expert: Many women with low-risk pregnancies successfully work out during pregnancy. But all should discuss this with their OB doctors at the first visit. Conditions change throughout pregnancy. Therefore, women should ask the OB at visits what is ok. Women with risk of pregnancy complications, history of preterm birth, etc. Should consult with OB and maternal-fetal medicine about what activity is safe.
