It’s taken sixteen weeks but I’ve gradually built up my standing ’embrace the tree posture’ to sixteen minutes.
And I haven’t had any major problems with my knees reacting against the stance. Apart from some minor soreness, the knees feel fine.
In the past I’ve tried to work through pain and practice lower stances which actually stressed my knees and caused pain. A silly attitude because it wasn’t in line with the Yin Yang philosophy of finding one’s balance. It took me a while to wake up to my self and focus on only doing exercises I could physically handle.
