The supine "Figure 4" stretch targets deep gluteal tightness to relieve sciatic nerve irritation and enhance hip mobility. To perform it, lie flat on your back with knees bent, cross one ankle over the opposite knee, and gently pull the uncrossed thigh toward your chest. Hold for 30 seconds while maintaining a neutral spine and breathing deeply, aiming for a comfortable release without sharp pain. Performed regularly, this simple technique serves as an effective tool for lower body rehabilitation.
