Anne, Scott Sonnon always says to trust your instincts. If you think something might flare you it's probably best to avoid it at first. You don't want to get a huge flair right off the bat. To be honest when I first saw this program I never thought I'd be able to do as much of it as I am now. I really didn't, but my body has gradually adapted.

Also, it might be best to just try a couple of things at first to test the water. Then, if you're doing OK you can gradually add more movements. I would also suggest keeping the pain level at a 2 or less at first instead of 4 like he suggests, just barely to the edge of the tension. Even that will probably cause some inflammation at first.
