Is poling *almost* everyday bad?

So my studio has a mix of classes from pole to polefit to floor work to exotic dancing and I've been taking two classes, five out of the seven days of the week.  But because of the scheduling, my rest days fall on Friday and Saturday so they are not spread out across the week.  I've heard that to build muscle mass you should throw in a rest day in between...so not sure if what I'm doing is bad or if it will hault progress.  Thoughts?  Advice?
