Hi Susannah
I’m sorry to hear of your pain.
Your problem is possibly due to the new skill overwhelm that most people experience (for the internalization of any new skill). It is entirely possible that due to the mind’s inability to pay attention to a hell of a lot of conscious activities that are in some way foreign to you that some strain has occurred.
So what may have happened is – if it is in Awkward pose – that most or all of your conscious attention was being paid to the travel down, a straight back or your arms straight or any number of other things. This probably left little or no attention available for squeezing your knees together. I am guessing with Pilates as one of your fortes you probably had your core engaged.
It is also possible that if your torso was leaning forward at all then there was more pressure on your knees.
It is very common for vital parts of the technique to completely drop or move in and out of awareness during this and every other pose… It’s part of the process. Just not very satisfying for you at the moment.
What do you think having read my ideas?
Namaste
Gabrielle 🙂
