The precautions for the third trimester include watching for signs of preterm labor, dehydration, safety issues, and symptoms of maternal supine hypotension syndrome. If you have any complications from these or other things that arise in your workout, stop exercising immediately. Call your doctor or midwife to discuss possible modifications.

Your prenatal appointments will be much more frequent at this point in your pregnancy. Be sure to ask your practitioner about exercise every visit to ensure you're both on the same page. This will also help both of you stay informed about your abilities and exercises.

There are no specific recommendations to stop exercising prior to labor. Many women go through pregnancy and exercise until the day of labor. Other moms might feel tired and worn-out, decreasing their workouts in intensity and frequency as they go. Either way is fine as long as it is what is right for you and your baby.

Warmups and Cool-downs

Your warmup during the third trimester really sets the tone for your whole workout. There will be days that you do the warmup and decide that's enough. The important thing to remember is to listen to your body. Again the warmup helps protect you from injury, so don't skip it in the interest of saving time or energy.

Your cool-down won't change, except perhaps to make it longer. Your body is slower to make transitions at this stage of pregnancy. Be sure to always include some mental relaxation as a way to stay focused on the mind-body connection.
