What might be causing round marks on an Asian or Asian-American woman's back?

At the gym over the past few months, I have seen a few Asian or Asian-American 60-something women with their backs covered with 1.5-inch - diameter circular marks. Does anyone know what may have caused these marks? Are they the result of a medical condition? A medical treatment? A common injury or abuse? The largest Asian-American population here is Korean. The marks are varying in intensity, so it looks like they occurred over a period of time.
