Just wondering if anyone elsehas read Katy Bowman's stuff, on Aligned and Well website. She's a biomechanist who advocates squatting, wearing completely flat shoes and walking a lot and says that lots of pelvic and back problems come from our limited rangeof movement and chronically tight muscles. I started trying to follow her advice this time last year and am now 8 wks pg. Am interested to see if it's makes a difference as I had PGP with first pg, came on during second trimester, and with second, started at 9wks. Anyone else?
