The Science of Exercise for Women 40+: What to Prioritise (And What to Ignore) | Dr Lauren Colenso-Semple and Dr Alyssa Olenick

Dr Lauren Colenso-Semple and Dr Alyssa Olenick join me to answer a question I hear constantly from women in midlife: “Why am I putting in so much effort, but not seeing the results?” We break down what matters most for strength, body composition, and long term health, and what is simply noise. You’ll come away with a clear framework for resistance training, a realistic view of cardio, and a calmer approach to progress that does not rely on fear, perfection, or menopause specific gimmicks.
