I'll be undergoing intrauterine insemination (IUI) in a few weeks. Is there any reason to discontinue my workouts until I know whether I'm pregnant?
There is no need to stop or limit your workouts while awaiting the happy news. In fact, the only precaution I recommend is that you lie still for 30 to 45 minutes immediately after your IUI to help increase the chances of insemination and to counteract any cramping you might have (cramping is normal after any uterine manipulation). After that, you're good to go.
As long as you are in good health and have no prior restrictions to your physical activity, I recommend that you continue exercising throughout your entire pregnancy. However, if there is any concern about vaginal bleeding, the potential rupture of membranes or other signs of preterm labor, you must discontinue your workouts immediately.
