Since so many muscles attach at the hips. It’s very important to keep them flexible. The same flexibility that helps you do a proper squat also helps you get out of your chair and maintain proper posture. Without flexibility in your hips it is nearly impossible to stand upright. Most people with desk jobs take on a hunched over position over time, which eventually leads to back problems and a some what neanderthal like posture. Here is a great stretch that anyone can do!
— Karen Voight 1Sit in a cross-legged position on the floor. Inhale and sit up tall. Hold your right ankle in the palms of both hands above your left knee. Relax the right buttock muscle and allow your right thigh and knee to drop toward the ground. Hold for 3 to 6 breaths.
2Move into a deeper stretch by grasping your hands together under your right leg and cradling your ankle and knee in your arms. Be sure that you sit up tall. Do not round or hunch your back. Concentrate on relaxing the right buttock muscle as your bring your leg closer to your chest. Hold this position and breathe for 20 to 30 seconds. Lower your leg and repeat on the other side (source).
