2019 Canadian Guideline for Physical Activity throughout Pregnancy
Key Findings
Outcomes evaluated: maternal, fetal or neonatal morbidity, or fetal mortality during and following pregnancy; evidence graded with GRADE; end users (obstetric care providers, exercise professionals, researchers, policy organisations, pregnant and postpartum women) gave feedback.
Panel's judgement: the benefits of prenatal physical activity are moderate and no harms were identified → net benefit expected to be moderate; recommendations judged feasible, acceptable and equitable, requiring minimal resources.
The recommendations themselves are not in the abstract (full text; not checked against the abstract): all women without contraindication should be physically active throughout pregnancy; accumulate at least 150 min of moderate-intensity activity per week; be active on at least 3 days per week (daily encouraged); include a variety of aerobic and resistance training, yoga/gentle stretching may be added; pelvic-floor muscle training (e.g. daily) may reduce urinary-incontinence risk; modify supine exercise if light-headed, nauseated or unwell.
The underpinning systematic reviews report lower odds of gestational diabetes, gestational hypertension, pre-eclampsia and prenatal depression with prenatal activity (full text; not checked against the abstract).
Practical Application
2019 Canadian Guideline (GRADE, AGREE II): the panel found the benefits of prenatal physical activity moderate with no harms identified; its recommendations (full text) anchor the prenatal week at ≥150 min of moderate activity across ≥3 days, mixing aerobic and resistance training, plus pelvic-floor training.
Use the 150-min / 3-day frame (full text of the guideline) as the concrete target where ACOG (REF-567) stays qualitative — after the OB provider has confirmed no contraindication.
Add daily pelvic-floor training as a standing item (incontinence prophylaxis with postpartum carry-over; full-text recommendation).
Swap supine-loaded work for incline/side-lying variants if supine symptoms appear (full-text recommendation).
Limitations
Presupposes medical screening the coach does not do; targets complication reduction, not performance maintenance — extrapolate intensity conservatively, defer to OB provider.
The abstract describes the method and the net-benefit judgement only; every dose figure in this entry is from the guideline's full text.

Dose figures (≥150 min/week, ≥3 days/week, daily pelvic-floor training, supine modification) and the underpinning meta-analysis outcomes labelled "full text; not checked against the abstract" — the abstract carries the method and "moderate benefit, no harms" only.
