During my Russian language studies, sometimes I get tired and I have to take a small break from my studies. The time period could be anything from a day to a week. I do this just to settle what I have learned. I found out that doing this allows my brain to “bake” what I just learned. However, during this time I do not do any language learning at all. For that reason, I thought in pick up a second language, Arabic to being specific. My idea involves use the “spare” time from Russian and uses it with Arabic.
My concerns are the followings:

Is this is a healthy approach to language learning?

Is it good for my Russian and Arabic?

Is it possible? Have any of you tried something similar? How you did it?

Any comments and/or suggestions are welcome.

What about the dialect, classical Arabic or Egyptian or any other?
