The rest of the story: Last autumn, I was planning a trip to Italy.
Right before i left, less than 3 days from my departure, my back went out.
I had no time to get an appt with a dr or chiro, so I posted here on TE.
Knot came up with this exercise (you guys have to tell me how you do the "hard" version, I'm idly curious (ie I don't want to do it but i wanna know))
which I was able to do every day, and by my 3rd day in Italy WITH a really really bad bed (hammock shaped mattress) I was improving thanks to her.
