Posterior Pelvic Tilt on Belly

Thank you for making these video's , they are very helpful. Could you please do a video on hefesto and iron cross?

My mid back hurts when doing posterior and anterior pelvic tilt when I'm laying down...?

Perfect. It balances many videos that teache to prevent posterior tilt, when 90% of people are in anterior pelvic tilt and don't know how to do the opposite, the posterior tilt.

Does this fix posterior pelvic tilt?

Will this create too much flexion on the lumber that can cause damage to discs?There is a lot controversy over this with emphasis on maintaining lordosis of the lumbar spine

wont this make it worse, like is this fixing posterior pelvic tilt? or fixing anterior pelvic tilt

This feels good when my low back hurts but it's weird because
I've been to many physical therapist and none of them suggested this excercise.
I discovered it by accident.

Yeah is it right to place the pillow under the pelvis.

I hope it doesn't work. becos it can cause anterior pelvic tilt

If this works will u pls tell the demonstration of placing the pillow

(like in which part it should be placed)
