The above figure illustrates how bone responds to stress. Below a certain threshold of strain, humans will lose bone. In the adapted state, bone mass will remain constant. Once sufficient loads are placed on bone, cells will respond by building bone. If the loads exceed the mechanical limits of the bone, fracture will occur.

If you’d like to learn more about bone modeling and remodeling, I strongly recommend this article by Robling and Turner.
