How much is recommended
For a pregnancy without medical or obstetric complications, the American College of Obstetricians and Gynecologists (ACOG) recommends around 150 minutes of moderate-intensity activity a week. That can be 30 minutes on five days, or 10-minute blocks across the day — the shape is yours, the total is what counts.
The most practical way to judge "moderate" is not a heart-rate number but talking: you are moving enough to breathe harder and start sweating, you can still talk normally, but you could not sing.
If you are not used to exercising, start at 5 minutes a day and add 5 minutes each week until you reach 30. Pregnancy is not the time to begin a demanding program — but it is not a reason to stop moving either.
What we train, and what we avoid
The focus is on the things that make pregnancy feel easier and recovery afterwards simpler: deep coordinated breathing, a pelvic floor that knows when to work and when to let go, hip and leg strength for standing and stairs, and how to lift and turn in bed without loading the back.
What we avoid: activities with a risk of falling or of impact to the abdomen, lying flat on your back for long stretches later in pregnancy because it can compress a major vein, breath-holding and straining, exercising in excessive heat, and scuba diving. All of this is adjusted per person, not applied as a uniform rule.
Frequently asked questions
I never exercised before pregnancy. Can I start now?
Yes, with a slow start. Begin at 5 minutes a day and add 5 minutes a week. What is not advised is jumping straight into a demanding program, or a new sport that makes big demands on balance. If your pregnancy has complications, check with your obstetrician before starting.
Can exercise trigger miscarriage or preterm birth?
For an uncomplicated pregnancy, moderate activity is actually recommended and has not been shown to increase those risks. Pregnancies with specific conditions are different — placenta praevia, a history of preterm birth, or pregnancy-related high blood pressure, for example. There the decision belongs to your obstetrician, and we follow their guidance.
How late in pregnancy can I keep going?
Many people keep moving right up to the last weeks, adjusting the exercise along the way. What changes is not "allowed or not" but the positions, the duration and the choice of movements as your body changes. As long as none of the signs above appear and your obstetrician has not advised otherwise, keep going.
