There is no way I could tolerate this without a major flare resulting.

I do slow, gentle stretches like I'm 80 years old and I still can get flares. I can stretch one night, and maybe by the next day I'm swollen and have to wait and work it out maybe for a few days or even weeks. I try to be so careful to get some stretching and some exercise into my life, but without causing extreme flares, as then I am forced to have no movement and walk around like Frankenstein, which seems counterproductive.

This "position" is waaaaay too extreme for what my body can handle.

I know we're all different, but I just want to point that out again...
