Yeah. Functional fitness kind of stuff where. And you're focusing on certain areas. So the bone loss comes mostly from your legs because you're not loading. So basically, our bones need a stimulus to regenerate, and it happens to us every day. So as you walk, as you go upstairs, that load that the bones feel, the compressive load is telling the bone, hey, make some more. Now you take that away and the bone stops making more. And that's the problem. People say, like, can't you just take, like, calcium pills? But it's not a mineral deficiency. It's just there's no load.
