Have you been told you can’t squat because you have bad knees, or that running will wreck your joints? In this solo nerd safari, Dr. Stephanie explains why that wear-and-tear story is wrong. Your cartilage isn’t a tire with a fixed amount of tread. It’s a sponge that has to be squeezed to stay fed. She covers how joints actually get their nutrients, why they recover so much more slowly than muscle, the morning stiffness pattern that deserves a doctor’s visit, and why joint pain becomes more common for women through perimenopause and menopause.
You’ll also hear what the research says about running, deep squats, and strength training versus stretching for mobility. Then comes the practical plan for training strong without getting greedy: how hard to push, a simple pain rule, and when to back off.
