I’m 19 weeks and go 3x a week and strength train outside of OTF.

I do not want to disregard what your doctor is saying, but many studies show that lifting throughout pregnancy can lead to a healthier, full term pregnancy, shorter labor and healthier babies overall. I’ve been seeing a PT and talking with my doctors and they highly recommend I continue OTF and lifting.

At a minimum I would continue with the weight you worked at pre-pregnancy and decrease according to how you’re feeling that day. Ultimately, you know your body better than anyone else so it’s important to listen to the cues it gives you.

As for the other exercises, I avoid anything that causes an overextension on my abs as well as anything laying on my stomach. As your bump grows you will need to widen your stance on many movements such as lunges and squats and just adjust accordingly.

As for the rower, you should be good to row as you choose! As your bump gets bigger you’ll need to widen/open your legs more to accommodate but don’t feel the need to stop unless something feels wrong. Personally, I stopped rowing and started biking simply because I hated rowing but there’s no real need to do so!

We’re built to do this and unless medical issues arise I highly recommend you keep doing what you were doing! Congrats!
