Show Notes
Is walking enough? Is Pilates enough? How heavy should you actually be lifting? If you’ve ever wondered which exercise really protects your brain as you age, especially through perimenopause and menopause, this conversation gives you the exact weekly plan.
In this episode, Tamsen sits down with clinical neurophysiologist and Alzheimer’s researcher Louisa Nicola, founder of Neuro Athletics and host of The Neuro Experience podcast, to talk about why she calls exercise medicine for the brain. Louisa explains that, outside of medication, exercise is the most powerful intervention we have to lower our risk of Alzheimer’s disease and dementia, a disease that affects far more women than men.
Tamsen opens up about the short-term memory loss and brain fog that scared her during perimenopause, and Louisa breaks down what happens inside your brain when you walk, sprint and lift, from BDNF and lactate to the myokines your muscles release. Then she builds out a workout plan for your brain: two days a week of heavy compound lifting at around 80% of your one-rep max, one Norwegian 4x4 interval session, zone 2 cardio and 10,000 steps a day.
In this episode, you’ll learn:
- Why exercise is the best non-drug intervention for lowering Alzheimer’s risk
- How heavy to lift for brain health, and why compound moves like squats and deadlifts matter most
- Why Pilates is a great add-on, but not enough on its own
- The surprising link between leg strength and brain aging: “the larger the legs, the larger the brain”
- What zone 2 training (about 65% of your max heart rate) does for the hippocampus and memory
- How to raise your VO2 max with the Norwegian 4x4, how to estimate it with the 12-minute Cooper test, and why she wouldn’t rely on your wearable
- What she says about creatine for the brain, omega-3s, and the p-tau217 blood test and APOE4 gene test you can ask your doctor about
If you’ve ever wondered whether your workouts are doing anything for your brain, this episode will help you build a plan that protects your memory now and decades from now.

Most of us have been taught that when something is not working, the answer is more discipline, more willpower, and more effort. Angela Duckworth, the University of Pennsylvania psychologist and bestselling author of Grit, built her career studying that idea. Her new book, Situated, asks us to look at everything surrounding that effort.
Menopause and perimenopause can leave you with questions about belly fat, brain fog, sleep problems and whether hormone therapy could help. Your jeans fit differently. You’re losing your train of thought. You’re exhausted, but you can’t sleep. Where do you start when so much feels unfamiliar?
Why do we keep choosing emotionally unavailable partners? And why is it so hard to break unhealthy relationship patterns, even when we know better? In this episode of The Tamsen Show, dating and relationship expert Sabrina Zohar joins Tamsen Fadal to explain anxious attachment, avoidant attachment, relationship anxiety, and how childhood experiences shape the way we love, date, and connect with others.
Women learn early which parts of themselves make other people comfortable. After enough years, that performance can begin to feel like our identity, and the intuition underneath it goes quiet.
