Clearance first, always
Before starting or continuing any exercise in pregnancy, get clearance from your doctor or obstetrician, especially if you have any pregnancy complications or pre-existing conditions. This article is general information, not medical advice, and it can't account for your individual situation. Your care provider's guidance always takes priority over anything here. A qualified trainer should work within that clearance, not around it - our prenatal and postnatal training is built to do exactly that.
If you'd prefer to train with a woman, that's completely reasonable and common in pregnancy - you can request a female personal trainer.
Trimester by trimester
Every pregnancy is different, but the general pattern of how exercise adapts is fairly consistent. Use the table as a starting point for a conversation with your provider and trainer - not as a fixed prescription.
| Trimester | Typical focus | Adapt or avoid |
|---|---|---|
| First (weeks 1-12) | Maintain gentle-to-moderate activity, manage fatigue and nausea, build good habits | Don't push through exhaustion; avoid overheating; ease off if very nauseous |
| Second (weeks 13-27) | Often the most comfortable - steady strength, mobility and low-impact cardio | Stop prolonged flat-on-back (supine) positions; watch balance as your centre of gravity shifts |
| Third (weeks 28-40) | Comfort, posture, breathing, gentle strength and mobility for birth and recovery | Reduce intensity as needed; avoid fall-risk and balance-heavy moves; expect to slow down |
What to avoid
- Prolonged lying flat on your back after the first trimester, which can affect blood flow for some women.
- Contact sports and fall-risk activities (for example, sports with collisions, or activities where losing balance could cause a fall).
- Overheating - avoid exercising in very hot, humid conditions or hot yoga; stay well hydrated, which matters in Singapore's climate.
- Breath-holding under load (the Valsalva manoeuvre) and heavy straining; keep breathing through effort.
- Anything that hurts or doesn't feel right - pain is a signal to stop and reassess, not push through.
Warning signs to stop and call your provider
Stop exercising and contact your doctor or obstetrician if you experience any of the following during or after activity. When in doubt, seek care - it's always the right call.
- Vaginal bleeding or any leakage of fluid
- Regular or painful contractions
- Chest pain, severe or unusual shortness of breath
- Dizziness, faintness or a headache that won't settle
- Calf pain or swelling (which needs prompt medical assessment)
- Reduced baby movements, or any symptom that simply worries you
A note on postpartum return
After birth, returning to exercise is also led by your provider. A common guide is to wait until around your 6-week postnatal check and clearance before resuming structured training, and longer after a caesarean or any complicated delivery. Early work usually focuses gently on breathing, core and pelvic floor before progressing. There are no shortcuts and no guaranteed timelines here - your recovery is individual. When you're cleared, our prenatal and postnatal training can help you rebuild at a sensible pace.
