Chronic tiredness isn’t a personal failure. It’s what happens when stretched lives run on restricted fuel, elevated cortisol and bodies that no longer trust supply.

Longevity has replaced thinness as the goal. This is the smarter, strength-first way women should be training now — for bones, brains and a body built to last.
