I found this the long way round. Years at a desk left me with a back that complained by mid-afternoon and hips that had quietly stopped moving. My first class was too fast and too full of poses I could not do, and I did not go back for a year.
The second one was slower. The teacher spent the first ten minutes on breathing and never once asked for anything impressive. That was the class that changed things — not because it was easy, but because it was repeatable.
That is what I teach now: short practices you will actually return to, a longer exhale than inhale, shapes taken to the edge of sensation and no further, and rest treated as part of the work rather than the bit you skip when you are busy.
Everything I teach in the studio ends up written down here, in plain language, so you can practise it at home on the mornings you cannot make it in.
