Pregnancy fitness advice has changed dramatically over the last few decades, but many parents still receive outdated recommendations rooted more in fear than evidence. After receiving outdated advice during her own pregnancy, exercise physiologist and prenatal/postnatal wellness practitioner Ashley Reid was inspired to help moms stay active through every stage of motherhood. In this episode, Dr. Rebecca Dekker talks with Ashley about the latest evidence on exercise and strength training during pregnancy and postpartum. Ashley shares why old recommendations like keeping your heart rate under 140 beats per minute are outdated, what the research actually says about lifting weights during pregnancy, and how to safely build strength in ways that support your changing body. She also explains her "Core, Function, and Fitness" framework and how to approach postpartum recovery as a gradual progression instead of a rush back to exercise.
