Grip, Legs, and Lungs: The three numbers that predict how you will age

Maeve Sutton

Most people track cholesterol and weight but never test how hard they can squeeze, how fast they can rise from a chair, or how long they can climb stairs without stopping. This lays out why those three plain measures predict independence decades from now better than most lab work, how to test each one safely at home, what a weak result actually means, and the specific training that moves the number. Clear, grounded, and built for the long run.
