They discuss the latest evidence on resistance training during pregnancy, including heavy lifting, Valsalva/breath holding, pelvic floor concerns, miscarriage fears, diastasis recti, and returning to exercise postpartum. They also explore why muscle is essential for aging powerfully, how pre-frailty can be reversed, and why women in perimenopause, menopause, and beyond should feel empowered to build strength instead of being told to "do less." In this episode, we discuss: • The benefits of resistance training during pregnancy • Heavy lifting and pregnancy: what the latest evidence shows • Pelvic floor myths and misconceptions • Breath holding (Valsalva) and lifting safely while pregnant • Diastasis recti: what it is and what the research says • Returning to exercise after vaginal birth and C-section • Why strength training supports mental health during pregnancy and postpartum • Pre-frailty and how it can be reversed • Building muscle for longevity, independence, and healthy aging • Common myths about women's health and exercise circulating on social media • Why fear-based fitness advice can hold women back from thriving Dr. Prevett's work is helping redefine how we think about strength training across the female lifespan—from pregnancy and postpartum to menopause and beyond. This episode is packed with practical insights and empowering evidence-based guidance for women who want to build strength, preserve muscle, improve body composition, and age powerfully.
