- It is rather challenging simply because you must have immense shoulder strength to lift up the head. Otherwise, of course, the head simply won't lift.
- Plus, with the hands locked, there is not much space or scope for manoeuvrability.
- The fear in this pose is more, since the neck must lift up confidently -- this is a very psychosomatic fear center and takes some mental effort. That may be why a lot of people fear the scorpion -- the same area is challenged.
- Staying up longer is the challenge. U wobble a lot in this pose and need loads of strength, the stay upright.
