This is a great routine. I teach pilates (or was teaching before the pandemic), and as one of my instructors told me, you can get a good workout in 1 or 1/2 class. This is a good example of that. It's beginner enough to make it accessible, but it's still challenging.
Great side lying variation for abductors. Simple instructions on angle, opposing action into the floor, and arm position will make for a hip opener revealing for you and your students. I plan on teaching the "reaching arm abduction".
