Hmm, that title sounds a bit judgey, but let me explain..
I'm only 6 weeks pregnant, and amongst the 10 million things I'm worried about is the fact I have a large, young, very bouncy dog, and pretty much NEED to avoid any kind of SPD/pelvic pain for as long as possible to keep walking/training him for when bubs appears.
So, just wondering anecdotally whether regular walking (which obviously I'm doing at the moment) can ward off problems, or if it is much less fair than that and strikes you anyway!
