Why Iyengar
The pose is fitted to your body, not your body to the pose.
No two bodies are built the same. Hips, shoulders and spines differ from person to person, and they change with age, work and old injuries. So why should everyone in the room be pushed into one identical shape?
Iyengar Yoga starts from that question. The teacher looks at how you stand, bend and reach, then adjusts the pose to suit you — with a block under the hand, a belt around the feet, a chair, the wall or the ropes. The pose still does its work. Your joints simply stop paying for it.
