Question asked by Chris Gellert, PT, MMusc &Sports Physio, MPT 1633 days ago
Why is the QL commonly tight in so many people based on the research?
one of the four dynamic stabilizers of the spine
Wild guess but going with sitting most of the day.
I agree with Bryant-it is from being in a seated position for so many hours during the day. The erector spinae gets weak and unable to extend the lower back and the QL functions in this capacity. The QL gets overworked and becomes short and tight.
