Exercise during pregnancy: a trimester-by-trimester guide

By Exercise Scientist & Rehab-Informed Personal Trainer

Pregnancy does not require you to stop moving. In fact, the evidence strongly supports staying active throughout — with appropriate adaptations and a coach who understands the physiology.

Why exercise matters more than ever during pregnancy

Current guidelines from ACOG, the CSEP Pregnancy Guidelines and NICE all advocate for regular moderate-intensity exercise throughout an uncomplicated pregnancy. The benefits are well-documented: reduced risk of gestational diabetes, better weight management, lower rates of pre-eclampsia, shorter active labour and significantly improved mood and sleep quality.

General principles

Aim for moderate intensity — the talk test is a reliable guide. Target 150 minutes of moderate aerobic activity per week. Movement quality over load becomes more important than the kilos on the bar.

  • Avoid supine work from the second trimester
  • Avoid contact sports and activities with fall risk
  • Introduce pelvic floor education from the first trimester
  • Learn to manage intra-abdominal pressure throughout
