Safe Exercises During Pregnancy by Trimester
Staying active in pregnancy eases back pain, improves sleep and mood, supports healthy weight gain and can make labour easier. Here is what is safe by trimester and what to avoid.
General guidelines
Aim for about 150 minutes of moderate activity a week if you are healthy and your pregnancy is uncomplicated. You should be able to talk while exercising — if you cannot, ease off. Always get your doctor okay first, especially with any complications.
By trimester
First trimester: keep up walking, swimming, stationary cycling and prenatal yoga. Start pelvic-floor (Kegel) exercises.
Second trimester: avoid exercises flat on your back; favour standing, seated or side positions. Continue low-impact cardio and light strength work.
Third trimester: lower the intensity and focus on mobility, breathing, pelvic-floor work and gentle stretching to prepare for birth.
Best safe exercises
- Walking — easy, low-impact, any trimester.
- Swimming and water aerobics — supportive and cooling.
- Prenatal yoga — flexibility, breathing, relaxation.
- Stationary cycling — cardio without fall risk.
- Light strength training with good form.
- Pelvic-floor exercises — support bladder control and recovery.
What to avoid
- Contact sports and activities with a fall risk (skiing, horse-riding).
- Scuba diving.
- Lying flat on your back after the first trimester.
- Hot yoga or overheating.
- Heavy lifting with breath-holding.
When to stop and call your doctor
Stop and seek advice if you have bleeding, fluid leaking, regular painful contractions, chest pain, dizziness, calf pain or swelling, or reduced fetal movement.
Frequently asked questions

Is it safe to lift weights?
Light-to-moderate strength training with good form is generally safe; avoid very heavy lifts and holding your breath.
