Variations include widening the knees (hip abductors), which can create a more neutral extension in the spine and make room for the belly; extending the arms overhead; clasping the heels with the hands; crossing the arms under the forehead; and turning the head to one side.
Sometimes there is congestion in the front of the hip joints, which can be caused by using the hip flexors to pull the body down towards the thighs, rather than allowing gravity to create that action. The use of props can assist in this release.
Restriction can also be felt in the tops of the feet, if the extensors of the toes are tight or if there is a lack of mobility in the bones of the foot. Additionally, weakness in the intrinsic muscles of the foot will often result in camping in this, and similar positions (such as virasana and vajrasana).
