Episode Details

Most people think exercise is just for their body. They're missing a $2.3 trillion opportunity happening inside their skull every time they break a sweat. Nina breaks down the latest neuroscience showing how a simple 20-minute workout literally grows new brain cells and boosts your memory for hours afterward. Turns out your brain craves movement more than your muscles do. What you'll discover: • Why 150 minutes of weekly exercise increases your hippocampus by 2-3% (that's your memory center getting bigger) • How high-intensity intervals spike brain-building proteins by 300% in just 30 minutes • The exact workout timing that improves focus for up to 4 hours afterward • Why people who exercise regularly cut their dementia risk by 40% This isn't about becoming a gym rat. It's about understanding what actually happens in your brain when you move your body, and how to use that knowledge to think clearer, remember better, and stay sharp as you age. Nina's treated enough patients to know the difference between what sounds good and what actually works. She walks through the research that's changing how doctors think about exercise prescriptions and brain health.
