4 myths about women's health

February 26, 2026

Key Takeaways Copied to clipboard!

  • Beyond annual mammograms, women must assess lifetime breast cancer risk using tools like the BCRAT calculator and consider factors like breast density and family history to determine the best screening plan, potentially including MRIs. 
  • Cardiovascular health is a leading killer of women, necessitating regular cardio exercise to maintain heart pliability, and gynecological history (like preeclampsia) should be discussed with doctors as a heart disease risk factor. 
  • The idea that workouts must be strictly timed to the menstrual cycle lacks strong evidence; consistency and listening to overall body signals (like stress or lack of sleep) are more crucial for effective exercise.

  • Key Takeaway: Many women lack adequate health education, leading to belief in unsupported wellness myths.
  • Summary: The episode introduces Meghan Rabbitt, author of The New Rules of Women’s Health, who asserts that health class often falls short for women. This lack of education contributes to the belief in unsupported health ideas, such as optimizing workouts based on the menstrual cycle phase. The research suggests that the most obvious, tried-and-true lifestyle advice is often the most evidence-backed.
Myth 1: Mammograms Only

  • Key Takeaway: Breast cancer screening requires assessing lifetime risk and considering breast density alongside annual mammograms.
  • Summary: Relying solely on annual mammograms is insufficient for breast cancer detection; women should calculate their lifetime risk using tools like the BCRAT calculator. Factors such as dense breast tissue (categorized A through D) and family history influence the need for supplementary screenings like breast MRIs. Scheduling MRIs and mammograms six months apart allows for two screenings annually, maximizing early detection opportunities.
Myth 2: Strength vs. Cardio

  • Key Takeaway: Both strength training and cardiovascular exercise are crucial, as heart disease is the number one killer of women.
  • Summary: While strength training is vital for bone health, cardiovascular exercise is equally important because raising the heart rate increases the heart’s capacity to fill with blood, keeping ventricles pliable. Heart disease awareness is low among women, despite it being their leading cause of death. Gynecologic history, such as experiencing preeclampsia or gestational diabetes, serves as an important indicator of future heart disease risk.
Myth 3: Menopause Misery

  • Key Takeaway: Menopause offers upsides like ending unpredictable periods and the freedom from birth control concerns, serving as a reset opportunity.
  • Summary: Obvious upsides to menopause include no longer having periods, which can be heavy and unpredictable during perimenopause, and no longer needing birth control. This transition can be viewed as an opportunity to press a reset button on life choices to feel better physically and emotionally. Menopause is officially defined as one day after a full year without a period; if bleeding resumes, the clock resets to zero.
Myth 4: Cycle-Based Workouts

  • Key Takeaway: There is no strong data supporting the maximization of workouts based on the menstrual cycle phase; consistency is key.
  • Summary: There is a lack of robust data indicating significant changes in strength or endurance based on timing workouts to the luteal or menstrual phases. External factors like stress or lack of sleep should influence workout adjustments more than cycle timing. For competitive athletes, training across the cycle at various intensities is beneficial since race days cannot be timed to a specific cycle phase.

  • Key Takeaway: Consistency in exercise and proactive discussion of risk factors with doctors are the overarching actionable themes.
  • Summary: The episode summarized four key myths, emphasizing that breast cancer screening requires risk assessment beyond mammograms and that heart disease awareness must increase among women. Consistency in exercise is prioritized over optimizing workouts based on cycle phases. Listeners are encouraged to subscribe to LifeKit Plus for exclusive content on related health topics.
