Open up tight hip flexors while standing.
Tuck the pelvis under to feel it. Arching the back hides the stretch.
Stepping one foot back and tucking the pelvis under puts a targeted stretch on the front of the rear hip, the exact tissue that shortens through hours of sitting. The muscles around the outside of the hip work to keep the pelvis square while you hold, one side at a time, so it is not entirely passive. It earns its place as the stretch you can do anywhere, no kneeling, no mat, just a doorway and thirty seconds.
Your pelvis is untucked and your lower back is arching, which hides the stretch completely. Squeeze the back glute, tuck your tailbone under first, and only then shift forward. Done right, the front of the back hip lights up within a small shift.
Kneeling usually allows a deeper stretch, but standing wins on accessibility, you can do it at a desk, in a queue, anywhere. A standing stretch you actually do daily beats a kneeling one you skip.
Thirty seconds to a minute per side, once or twice through, and daily if you sit a lot. Frequency matters more than heroics, hip flexors respond to regular gentle exposure, not one long weekly wrestle.
