Your hips aren’t actually tight. Your psoas, iliacus, and glutes are.
These three muscles work together to control every hip movement you make, and when they lock up, your whole lower body pays the price. The psoas runs deep through your core, connecting your spine to your legs. The iliacus sits right alongside it, tucked into the inside of your hip bone. Your glutes anchor everything from behind. Sitting for hours shortens the psoas and iliacus while shutting your glutes off completely. Stress tightens all three at once.
This is why traditional stretching never works. Pigeon pose, lunges, foam rollers, none of them reach deep enough to release the iliacus or psoas, and rolling your glutes on a lacrosse ball barely scratches the surface.
The Thrival tool was designed to hit all three. The shape lets you sink into the psoas and iliacus from the front, then flip and release your glutes from underneath. Sixty seconds per area is all it takes.
Stop stretching muscles you can’t reach. Release them at the source.
