Which stretches are dangerous?

[sensei8]

Every advice I've read here thus far have been good, but, I'd caution you to first consult with your doctor for the answer that best fits you in your current condition. Ask you doctor to avoid any unnecessary injury to yourself.

I don't think many of them are wrong if you do them right. But of course you have to listen your body, like on those streches that migh be bad for knees..I don't do them if they feel even a little bad. In every strech back should be straight while bending forwards.
