Quadratus lumborum
Rolling and stretching of the quadratus lumborum is essential for the proper functioning of the hip joint. If it becomes too “strong”, it can cause a number of posture defects and consequent pain (it is responsible for pelvic bone tilting).
It belongs to the *deep muscle chain of the front, so it is worth dealing with all the muscles of the chain, rolling, stretching.
Roll both quadratus lumborums on each side, stretch them.
The presented image and video material can be done for everyone, but in case of any injury, a consultation/survey is recommended for individualized training.
