Sit tall and cross one ankle over the opposite knee, letting that knee fall open to the side. Keeping your back reasonably flat, hinge forward from your hips until you feel the stretch through the glute of the crossed leg. Press gently on the inside of the crossed knee with your hand if you want more depth, rather than forcing your whole torso lower. Keep your spine long instead of rounding through your lower back to get closer to your knee — the range should come from your hip, not your spine folding. This is the simple seated version; it works anywhere you can sit down, chair or floor.
