Hips rotate forward causing lengthened hip flexors and shortened lumbar extensors (Figure A) After long term exposure to this positioning the muscles will adjust to these improper lengths. Figure C ...

Just like major muscles including your glutes ... between the energy cost of running and the balance between hip flexor and hip extensor strength (among other strength variables).

Medical term: Hip flexors are a group of muscles and tendons located at the top of your thighs. They attach your femur to the lower spine so you'll usually feel hip flexor pain in the upper groin.
