That depends on your body. Some people maintain muscle very easily, others struggle to keep it on.
Just have to play around with it until you get it right. I know it's not the best answer, it's the reality of it.
I would recommend starting with two times a week, see how your body responds, and go from there.
For me personally, I can maintain my muscle without adding weights if I'm just training in class. But if I add cardio, I have to lift all the time. My body responds very quickly to cardio, but very slowly to weights. Your body will be different, and you just have to figure out what your body responds to.
