I saw something on TV years ago, study of chickens about that, saying you needed a certain minimum amount of shock loads to maintain bone density, this was the same time as touting of "low-impact" workouts. However, as I recall, it doesn't take much, you don't need high-volume of impacts. So my question is, I wonder if hard climbing out of the saddle, is enough, or do I still need a small amount of running or walking?
