Hello King Marki,
You will find alot of information on the web about this topic “Lordosis”.
Here’s a good start:
Wishing You the Best!
I am making reference to Kendall as I disagree with the two previous comments:
“The scientific definition of swayback refers to a posture in which the hips are swayed forward and the rib cage is swayed backward in the sagittal plane (Kendall 2005).”
It is tricky to see and can easily be confused with lordosis. Here is a very good reference with more information on this subjct www.bt.com.bn/features/2011/01/23/swayback-and-how-improve-your-posture
Here is more from IDEA and Justin Price on anterior pelvic tilt and lordosis.
Hi. Sway back is also known as lordosis. Here is a link from Cedar Sinai on the condition: http://www.cedars-sinai.edu/Patients/Health-Conditions/Swayback-Lordosis…
I hope that this helps.
