How to Correct Hyperflexion Syndrome Caused By Too Much Sitting
Excessive Lumbar Lordosis and Hyperflexed Iliacus muscles result in inhibition of the Glut Max and Hamstring extensors. Doing Squats to get those Gluts going will only result in overuse of your back and Quads. Before exercise to build the buttocks, it is necessary to turn the muscle "ON" or facilitate it. This can be done temporarily through direct activation techniques such as MAT or massage.
Too much sitting contributes to foreshortened Iliacus muscles. This may also be accompanied by excessive lumbar lordosis on one side resulting in an anterior tilt to the pelvis and possible Torque.
To change the body's chain of command to facilitate the hip extensors you need to reduce the tone in the back extensors first. This is easily done by using 2 balls in a sock placed in the L5/S1 junction while lying on your back with your knees up and your hands clasped behind your knee. Breathe and relax your back into the balls. Once the back has settled, begin slowly adding pressure into the restraint provided by your clasped hands. About 5 to 10 lbs is plenty. The less you do the faster your body will be able to figure out how to turn ON the Hamstrings and Gluts for hip extension and OFF the back extensors. Combine this with some regular stretching of the hip flexors and you'll be able to stand up straight again!
Sounds simple enough but ...this is actually quite difficult to accomplish and feels exhausting to the brain. Remember, the less force you use the faster your body will change.
