I’d suggest looking into Pimsleur’s courses. They have a Russian course, though I haven’t used it myself, their courses are well-done, providing a phrase-book-like approach while also introducing you to various grammatical structures/points. I’d also suggest posting to the R/Russian subreddit, (they may also have resources there.) The “Be Fluent In Russian,” YouTube channel has some useful grammatical and vocabulary videos narrated by a native speaker.

Maybe a bit much for what you're looking for but maybe you'll be able to find some good stuff in the guide I wrote on this topic: $1

Audio-wise though I'd recommend Michel Thomas, there's probably a russianpod101 or similar, things like that. Thomas gets a bad rep from some, but the Russian course is to my knowledge taught by an actual Russian lady, so should be pretty useful.

Similarly the \*pod101 podcasts get a bad rep, rightfully so, for the disgusting amounts of marketing they tend to bombard you with. I personally don't have an issue ignoring this, but if it's a problem for you you might opt for their audiobooks instead which are essentially the podcasts without all the fluff.

Hope that helps :)

DuoLingo recently released stories and audio lessons. I would think they would just support the existing learning materials though.
