Sitting all day leads to glute inhibition and quadricep dominance. When we sit all day, the glutes are seldom called upon to perform their primary purpose, which is hip extension (pulling the leg behind you). So we end up with tight, overactive hip flexors, and weak, overstretched glutes. When the glutes no longer work properly, the hamstrings and lower back muscles must compensate and work double-duty.
Weak glutes/tight hip flexors also lead to shortened hip extension movement, which leads to a compensatory over-arching of the lower back (increased lordosis). This leads to compression on the facet joints and intervertebral disks. When the pelvis stays tilted forward (the increased lordosis, above), the abdominal muscles become overstretched and weakened, and the lower back muscles shorten and tighten. So you are left with overactive and abused hip flexors and lower back muscles, and glutes and abdominals that are not working. If you wanted to create a recipe for low back pain and dysfunction, the list of ingredients would be:
- tight/overactive hip flexors and quadriceps
- weak/inhibited glutes and hamstrings
- weak abs and tight lower back
- anterior tilt of the pelvis (hyperlordosis of the lumbar spine)
