That is interesting Lucy. Glad it helped.
Bowman is an advocate for the whole body, weight baring movement and a lot of her stuff is very much about alignment and better movement (and sitting in many different ways) so the body doesn't end up with the weakened/ strained muscles and ligaments that lead to longer term issues.
She's very into hiking due to the way it exercises so many different pelvic, foot and leg muscles. ( barefoot!) have to say my lower back improved loads when we spent a half term doing lots of walks with a kid in a sling on my back.
It's just hard to wade through her stuff as she writes a huuuuge amount.
I'd agree with you 0noneO and purple.
