Learning objectives

  • Apply the 2019 Canadian and ACOG prenatal guidelines
  • Prescribe aerobic, resistance and pelvic floor training
  • Monitor intensity with RPE and the talk test
  • Modify exercises as pregnancy progresses

Before this lesson

Why this matters

Exercise in uncomplicated pregnancy is safe and benefits mother and baby.

Benefits

Reduced risk of gestational diabetes, pre-eclampsia, gestational hypertension, excessive weight gain and depressive symptoms [mottola2018].

Prescription

ComponentGuidance
Aerobic≥150 min/week moderate over ≥3 days [mottola2018]
Resistance2–3 days, moderate loads
Pelvic floorDaily PFMT [woodley2020]
IntensityRPE ~12–14/20; talk test
EnvironmentAvoid excessive heat; hydrate

Previously active and elite athletes can often continue higher levels with medical guidance [bo2016] [acog2020].

Modifications

  • Replace supine work if it causes dizziness or discomfort
  • Reduce loads and range as needed
  • Avoid breath-holding with heavy loads
  • Manage abdominal doming

Common mistakes and misconceptions
