@ellerbracke, @contentandwell, Oh dear me no....I can't get my butt to touch my heels. I couldn't even do that before the TKR. I am always working toward that goal even if I never make it. It does release the back and I stretch my arms out in front as much as possible because of all the shoulder surgeries. I also find that "pigeon" gets your knee to bend and I can hold my foot to help it a bit. Do you do pigeon? That pose is great for hip flexors and most especially to prevent sciatica. As long as I do "pigeon" and a twist on the floor every day...my back is in good shape. Those are the 2 must yoga poses for me and my spine for at least 20 years. Maybe there are other poses I should be trying. I do elder/senior yoga. Like you, I just want to keep moving. May you have relief from pain today. Chris
