The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
So if you're lifting something heavy when you're climbing stairs your bone senses that they need to support a greater force and in response to that it remodels by depositing more and more bone tissue. So bone mass increases in the presence of stress.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

So, think about how muscles act, right? So, a muscle by definition has to have attachments to bones, right? That's how the system works. And a muscle is never attached to the same bone because then it wouldn't do anything. Contracting a muscle on the same bone doesn't do anything. So muscles have to go across joints, right? So your bicep actually crosses a couple of joints, right? So you have a bicep that is attached to the bones of the lower arm and then attached to the bones of the upper arm. And so then when it contracts, it actually u closes that angle of the arm. Okay. So muscles are attached via tendons to bones. And think about like what we do with our muscles. Think about the load we put on those muscles. Well, the very simple laws of physics tell you that the bones have to feel that load. And we often don't think about that, right? We think about, you know, if you're doing a curl with 40 lbs, obviously your bicep muscle is exposed to that. But guess what? the tendon that is attaching the bicep above and below the joint of the elbow is also feeling that and the bone cells actually sense that load.
