In this discussion, Dr. Christina Prevett presents Push-ups Before Push Time, where she challenges outdated, fear-based exercise restrictions for pregnant and postpartum women. Dr. Prevett—a pelvic floor physiotherapist, researcher, and competitive strength athlete—draws on her clinical work, research at the University of Alberta, and her own athletic pregnancies, to argue that movement during pregnancy should be guided by evidence and individualized capacity, not blanket bans. General guidelines mirror those for non-pregnant adults—150 minutes of moderate aerobic activity per week, plus resistance training—but Dr. Prevett highlights how recent studies support lifting heavier weights, maintaining supine positions if tolerated, and continuing high-intensity intervals safely when individualized monitoring is in place. Miscarriage risk, diastasis recti, and rigid heart-rate caps lack evidence as reasons to limit exercise, and she emphasizes that deconditioning often poses greater risks than carefully progressed training.

Dr. Prevett dismantles long-standing myths—from the “20-pound limit” to fears about abdominal “coning”—by showing how new data and nuanced coaching can empower pregnant athletes and everyday exercisers alike. She advocates reframing diastasis recti as a manageable adaptation, not an injury, and encourages clinicians to support progressive loading, core strengthening, and breath strategies based on individual comfort rather than rigid rules. Her research also points to potential benefits of movement in high-risk scenarios—such as prolonged pregnancy after premature rupture of membranes—and questions the routine use of bed rest or “pelvic rest,” which often lacks evidence and may worsen outcomes.

The presentation also addresses practical implications for clinicians and fitness professionals. Dr. Prevett urges providers to “bulletproof” rather than “bubble-wrap” pregnant individuals by tailoring exercise to their baseline fitness, goals, and symptoms—then supporting early, gradual postpartum activity rather than enforcing a uniform six-week rest. The conversation with Karen Thomson also touches on perimenopause, menopause, and geriatrics, extending the same principle: that effortful, appropriately dosed strength training across the lifespan improves resilience and quality of life far more than overly cautious restrictions.
