I shared this on the live chat today (in a wobbly manner).
I have a yoga "pelvic swing" attached to some eye bolts that are attached to the studs in my wall (had this professionally installed).
Here is the source of the yoga swing/pelvic swing: https://www.yogawall.com/pelvic.html
I've also tried the "over the door" hanger on the same page which is easy for a non-carpenter to install.

i took a look. I would make sure that the ribs were anchored and no pelvic tucking when using the swing.
