Raising Strong Girls: Puberty, Hormones, Nutrition, Strength Training & Confidence w/ Dr Stacy Sims

A science-backed conversation for moms, women, and coaches shaping the next generation. Puberty. Hormones. Sports. Confidence. Nutrition. Strength training.
In this powerful and eye-opening conversation, Brittany Anderson sits down with Dr. Stacy Sims, world-renowned exercise physiologist and women’s health expert, to talk about what every parent, coach, and young woman needs to understand about teenage girls, puberty, and physical development.
This episode dives deep into how nutrition, strength training, sleep, and coaching directly impact a girl’s confidence, resilience, hormonal health, and long-term well-being—especially for girls involved in sports or high levels of physical activity.
Together, Brittany and Stacy break down why girls are not small men, why traditional coaching and training models often fail young women, and how we can build strong, empowered girls from the inside out—physically, mentally, and emotionally.
They also explore the often-ignored intersection between puberty and perimenopause, highlighting how changing the conversation now creates healthier, more confident women later in life.
If you’re a parent of a teenage girl, a coach, an athlete, or a woman passionate about empowerment, education, and resilience, this episode is required listening.
