Hi
Dont have a solution but wanted to say thanks for this thread. I'm watching it very closely for a solution because I am in the same boat as you Eva, probably worse since my hamstring flexibility isn't even as good as yours. I have scoliosis and wore a brace for two years when I was a teenager. Kept my spine ramrod straight which I always thought was a good thing since people always told me I had great posture and I have never had any back pain. It wasn't until GB that I even considered this an issue. Jc looks terrible and can't even roll up into a tuck up for manna pe 1 cause my spine doesn't flex too easily. Still debating how crazy I should go trying to fix this and if I'll actually cause some instability elsewhere by forcing my spine to curl.
