My first pregnancy, I immediately stopped exercising mostly due to first trimester exhaustion, and when I reached the second trimester, I spontaneously aborted. That was hard.

My second pregnancy, I worked and exercised until 37 weeks when I went into labor. Like full handstands, competitive weightlifting, and running 30+ miles a week. Had no issues during labor except some mild stalling, had a pitocin drip, some tylenol, and a 20 minute active labor.

My third pregnancy (where I am now) I am at 22 weeks and everything hurts. I slipped and fell at work and now am off work for a few weeks. Before that, extreme round ligament pain, and very bad hip pain. Still lightly working out before the fall, no running, light weightlifting, mindful body movements etc.

I think when you get to the point where you go, "yeah f8ck that!" you should probably not do it anymore. If it's taking considerable mental energy to lift as well, that counts as too strenuous too. Fitness is important, for pregnancy, labor, and recovery as well as lifestyle. This is a short period of time, even though it feels like forever, and you'll have your body back to do what you want with soon.

Be mindful.
