🧘Learn Why Stretching Works

Stop repeating gym-floor folk wisdom about stretching — build a science-grounded model that explains viscoelastic creep, stretch tolerance, and why static and dynamic stretching feel completely different, then write your own two-minute explanation of what's really happening when you reach for your toes.
