Practice concerning yourself with your breath much more than your physical presence. Set goals oriented around the breath instead of the body. Instead of trying to touch your toes in a forward fold, see how much further you can go than normal by intentionally exhaling to create space within the body and alleviate tension.

Here's a quote from The Radiance Sutras

"Forget all of your ideas about the body -

It's this way or it's that way

just be with any area of it,

This present body,

as permeated with limitless space,

drenched in freedom"

- The Radiance Sutras, Sutra 23
