About this episode
Is Zone 2 cardio really the key to longevity and fat loss—or have we been misled? In this solo episode, Louisa challenges the fitness status quo and reveals why low-intensity steady-state cardio might be wasting your time—especially if you're a woman. Drawing on new 2025 research and her deep background in exercise physiology, Louisa explains how men and women respond differently to training , and why higher-intensity workouts may be far more effective for improving mitochondrial health, brain aging, VO2 max, and metabolic flexibility. If you're a woman in your 30s, 40s, 50s, or 60s trying to optimize your longevity, brain function, and body composition—this is a must-listen. True optimization and longevity never come from comfort alone. You'll learn: Why Zone 2 may not improve mitochondrial health like you think The real training zones that boost VO2 max, fat oxidation & brain function How perimenopausal and menopausal women must train differently The exact weekly routine to optimize longevity, body comp & cognition *** Subscribe to The Neuro Experience for more conversations at the intersection of brain science and performance.
