It's obvious, I want to be better than I am. Not on purpose, but my pictures teach me this. My hips fall backwards, the back is rounded, the head is moving forward so that I can touch the leg with my chin.
Also this asana aims at the hips, the muscle and the joints. Ideally one lifts up the leg straight. The back remains straight, the neck is in line with the spine. Dristi is the toe.
I tried it again. I think it even looks better.
There is no easy asana. My focus will be the hips and the hamstrings and not bringing the head to the leg.
The secret is repetition, deep breathing, relaxing into the pose, holding it longer and enjoying it.
