Have you been reading what I'm saying? I don't trust western medicine either, but equating western medicine to Yoga and/or Pilates doesn't make a lick of sense. Pilates was developed by a man and refined by he and a woman, though the woman gets very little credit, mostly for women (ballet dancers in particular) and people recovering from injury and illness.
https://www.pilates.com/BBAPP/V/pilates/origins-of-pilates.html So please learn about what you are discarding off hand at the suggestion of a woman who is clearly out for profit.
I did read enough to see that she does advocate forcing the posture, did you read the quote I posted from the review?
I went to military school and was never told to eliminate the natural curvature of my spine, only hold it. There were two people in my squad who had to change their lumbar curve, one male and one female, both with lordosis, both were horribly out of shape when they arrived.
My problem with this woman is that she is flat out lying to get money from women and using sexism as a tool to do it.
