2h 24mKey Takeaway
Exercise is the best medicine, starting young. The earlier you start and the better base you build, the easier it is to maintain fitness over time. For young girls, building bone density before age 19 is critical—osteoporosis truly is a childhood disease. Focus on varied movement, resistance training (like Romanian deadlifts), and adequate nutrition to fuel performance rather than restrict calories.
Episode Overview
Dr. Abby Smith-Ryan discusses exercise and nutrition strategies for women across their life cycle, with particular focus on how the menstrual cycle impacts training, recovery, and nutrition needs. The conversation covers bone health development in youth, training adaptations across the menstrual cycle phases, and practical strategies for optimizing performance through proper nutrition timing and supplementation.
Key Insights
Osteoporosis Prevention Starts in Childhood
Women reach their genetic ceiling for bone density around age 19, then spend the rest of their lives maintaining what they've built. This makes childhood and adolescence critical for bone health. Resistance training and varied sports participation during youth create a foundation that protects against osteoporosis decades later.
The Menstrual Cycle Significantly Impacts Training and Recovery
Women can train at any phase of their cycle, but the luteal phase (week before menstruation) brings increased metabolic rate (200-300 extra calories burned), greater inflammation, fluid retention, and potential mood changes. Strategic nutrition and supplementation during this phase can significantly improve recovery and performance.
Protein Requirements Are Consistent But Often Unmet
Women should target 1.6 grams of protein per kilogram of body weight daily, regardless of cycle phase. While muscle protein synthesis appears unaffected by menstrual cycle phases when protein intake is adequate, many women struggle to consistently hit this target, especially during travel or busy periods.
Creatine Offers Unexpected Benefits for Women
Beyond its known performance benefits, creatine helps combat luteal phase bloating by pulling extracellular fluid into muscle cells. This addresses one of women's most common complaints during the pre-menstrual week while supporting performance. Dosing recommendations range from 5-10 grams daily after an initial loading phase.
Young Athletes Need Education About Menstruation and Nutrition
The onset of menstruation often marks when girls leave sports, partly due to lack of understanding about how the cycle affects performance and body changes. Proper education about nutrition as fuel (not restriction) and normal hormonal fluctuations can help keep young women in sports longer, protecting long-term health.

"Exercise is the best medicine."
"The earlier you start and the better base that you have, the easier it is over time to maintain that fitness."
"Osteoporosis is a childhood disease."
"I grew up in a space where it was exercise more and eat less."
"Women can train at any given time in our cycle. But what we do see is it's very clear that women and girls feel worse during different phases of the cycle."
Action Items
-
1
Encourage Multi-Sport Participation in Young Girls
Avoid early sport specialization. Have young girls participate in multiple sports and activities to develop different muscle groups and movement patterns. Include resistance training with exercises like Romanian deadlifts starting around age 11-12 to build bone density and prevent injury.
-
2
Optimize Luteal Phase Nutrition and Supplementation
During the week before menstruation, increase omega-3 intake to 2-3 grams daily to reduce inflammation, ensure adequate zinc and magnesium for sleep and vasodilation, and consider 5-10 grams of creatine daily to reduce bloating by pulling fluid into cells. Increase calorie intake by 200-300 calories to match elevated metabolic rate.
-
3
Prioritize Protein Intake Throughout the Cycle
Target 1.6 grams of protein per kilogram of body weight daily (or about 1 gram per pound as a practical goal). Focus on protein timing around workouts and avoid going more than 5 hours without protein intake to maintain amino acids in the bloodstream. Pack protein-rich travel snacks to maintain intake during busy periods.

4
Track Your Cycle to Optimize Training
Use at-home monitoring tools to understand your individual cycle patterns. Plan to push harder during the follicular phase (days 0-14) when you naturally feel better, and be more strategic about recovery during the luteal phase. Don't avoid training during any phase, but adjust recovery strategies based on how you feel.
