There’s really no substitute for playing the instrument and repetition of the stretches you’re having trouble with until they become easy.

Justin Sandercoe has some exercises. I remember him mentioning them during a video of one  of his Lee Anderson lessons. You’ll have to search.

I use a lot of warm-up exercises from Pasquale Grasso.
