It isn't. Bone is living tissue, constantly broken down and rebuilt, and it responds to stress exactly the way muscle does: load it, and it grows stronger and denser. That one fact changes the whole question. Bone health isn't something you're stuck with — it's something you build, and the same training that builds muscle is reinforcing the skeleton underneath it.\nThe rebuilding runs on a process called remodeling: specialized cells called osteoclasts clear away old, damaged bone while osteoblasts lay down new tissue. Peak bone mass arrives in the late twenties to early thirties, and from there it's a slow decline — faster for anyone inactive, under-eating, or skipping resistance work. The most effective defense is loading bone on purpose. Strength training pulls on bone and signals it to densify, and it builds the balance and stability that prevent the falls that fracture weak bone in the first place. Plyometrics — jumping, hopping, the explosive movements most people skip — add the dynamic, high-impact load that bone responds to best, especially in the hips and lower body where osteoporotic fractures tend to happen. And these habits compound, so the work done in your twenties, thirties, and forties sets your fracture risk decades later.\nMovement only pays off if the raw materials are there, and strong bone is a team effort. Calcium is the building mineral, but it needs vitamin D to be absorbed, magnesium to keep its balance, and vitamin K to direct it into bone rather than into blood vessels. Protein matters more than most people assume — bone isn't pure mineral, it's built on a protein matrix, largely collagen, that gives it flexibility and structure (and collagen isn't just for women). Chronic under-eating and crash dieting starve that whole system. Sitting on top of all of it are the hormones: estrogen slows bone breakdown in both sexes, which is why loss...","thumbnail_url":"https://img.transistorcdn.com/P6-Fwi0tU-MslFf88Jx6P5Vfzi1hBEH6zBCkjt_-K_Q/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS84NTVj/NjBmNDQ2M2U1NTZm/ZTllMDc1ODIwNTk1/OWYzYi5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
