Try this if you're feeling particularly stressed and just need to rest, relax and restore.
1) Put a folded blanket, bolster or pillow next to a wall
2) Get as close to the wall as you can, place your feet on the wall and shimmy yourself up on your prop
3) Situate the prop under your lower back and bring your legs straight up the wall if you can (you can also cross your legs if it's not comfortable to have your legs extended up the wall)
4) Roll your shoulders back and bring your arms out to the side, palms up
5) Relax here and hold for a few minutes while breathing into your belly
AHHHHHHHHHHHHHHHH - Fabulous
