Stand with your feet hip-width apart, or together if that feels right. Hinge at your hips and let your arms hang down. Don't round your spine; the bend comes from your hips, not your back. Lower your torso as far as it feels good, maybe reaching toward your toes or just holding your shins. Your knees can be slightly bent if you need it; flexibility isn't about forcing straight legs. Breathe and settle into the depth you have today. Some days you'll touch your toes; other days you'll reach your mid-shin. Both count.
