HIP MOBILITY
The hip opens better when the foot, pelvis, core, and glute stop arguing with each other.
Hip mobility is often treated like a flexibility problem. From the Feet Up sees it as a signal problem too: what are the feet doing, where is the pelvis sitting, are the glutes participating, and can the core support new range?
The hip is where the foundation meets the trunk. If the foot collapses, the pelvis dumps, or the ribcage drifts, the hip may guard instead of opening.
Hip flexor and psoas stretches can help, but only if the body learns where neutral is. Otherwise the low back may borrow the motion and call it hip mobility.
Big toe pressure and arch control can wake up the inner calf, adductors, glutes, and deep core. The hip receives better information when the foot is not passive.
Mobility becomes useful when the body can control it. Squats, hinges, split-stance work, kneeling, walking, and floor transitions all teach the hip to own range instead of visiting it.
Tight hips can come from sitting, old injuries, weak glutes, poor pelvic control, limited foot pressure, stress, or ranges the body does not trust yet.
Usually not by themselves. Pair stretching with foot pressure, glute work, core stacking, breathing, and strength in the positions where the hip feels restricted.
