Heart-Rate Zones, Wearables & RPE Guidance

In this episode, Dr. Stacy Sims returns for her fourth appearance on the podcast to share her latest insights into women’s health, performance, and longevity. She clears up common misconceptions about aging and fitness, emphasizing the importance of foundational practices - sleep, nutrition, and consistent training - over chasing advanced supplements or quick fixes.

Dr. Sims highlights the gender differences in exercise research, explains why women need tailored approaches to training, and explores how HIIT, resistance workouts, and structured year-round plans can transform strength and resilience. The discussion also covers gut health, menopause hormone therapy, protein timing, and strategies to keep young girls engaged in sports.

KEY TAKEAWAYS

• Start with the basics – Sleep, nutrition, and consistency matter most for longevity.
• Female-specific research – Women need health and fitness strategies rooted in their physiology.
• Tailored training – HIIT, resistance, and recovery should shift with life stages.
• Hormonal health – Perimenopause and menopause impact performance and should be understood.
• Gut & supplements – Creatine, glutamine, and nutrition can support muscle, energy, and digestion.
