Resistance training

Lifting weights 2-4 times a week to build and hold muscle

Barbells, dumbbells, machines or bodyweight, usually two to four sessions a week. Beyond looks, the case made across these stacks is muscle and bone as a retirement account: strength and lean mass predict independence and injury resistance decades later. It is the most widely shared item in this directory, recommended by people who agree on almost nothing else.
