whiter, I think Adriene has a short lower back one which is gentle. When I had lower back/hamstring issues the physio recommended bridge pose (great with a block under your lower back) similar to camel but less strain as your lying down, supine twists also.
August my shoulder is twingy after the Complete Vinyasa twisty one, it obviously worked hard yesterday, so those practices obviously use those shoulder muscles quite a bit! Today, I went back to Shiva Rea and did her Heart-Air practice, from the one I linked to earlier, as it's very shoulder opening but you still work hard, standing slits, bow poses, etc. I'm feeling pleased that I'm back to doing regular vinyasa flow, now.
