So it turns out that strength training is probably the single best thing you can do. And this was a surprise to me, 'cause we, you know, we did an AMA on this topic a little while ago, and that's when I got really deep on this with our analysts. My assumption was running must be the best, like some sort of impact must be the best thing you can do. You know, I assumed running would be better than swimming and cycling. But it turned out that power lifting was probably the best thing you could do. And I think once you understand how bones work, it became more clear, which is, you know, power lifting is really putting more of a sheer force from the muscle via the tendon onto the bone, and that's what the bones are really sensing. They're sensing that sheer force that's being applied through the bone, in a compressive way, depending on the bone of course. And that's what's basically activating the osteoblasts, which are the cells that are allowing bone to be built.
