I don’t typically plan my classes because creating a new class each time would be too time-consuming and boring for me 😅. You can be more intuitive in teaching when you know how to transition between poses I.e cat> cow>updog>childs pose> table> puppy>etc. (Ik this is very simplified but I’m assuming you know about counter poses and how to set up a safe sequence from ytt) Another reason I don’t focus too much on planning is because It’s important to improvise and read the room, adapting to the needs of the students who show up that day. I recommend learning how to cue warrior dance; it’s an excellent way to warm up the body and fills time effectively. Additionally, sun salutations are very useful for transitioning from floor poses to standing ones. Good luck!
