When we sit for most of the day, the head of the femur tends to sit in the anterior aspect of the hip capsule. While this may seem like ‘no big deal’ it’s actually a huge deal because it decreases the space you have for hip flexion movements (squatting, deadlifting, running) and increases your risk for injury to the hip joint. Not to mention your lack of hip flexion is now putting stress on your psoas and lumbar vertebrae. This improper position can also cause pain in the front of the hip during full flexion movements.
This self posterior hip mobilization is a crucial aspect in preventing hip injuries and resolving pain.
