Supine positioning provides the support and reinforcement of the floor/plinth that may be necessary to assist the client to perform the exercise with control and focus.
Once the supine position has been mastered OR if this position is uncomfortable or not ideal for the client then:
The exercise could be performed in a standing position against the wall;
Ensure that the client’s balance profile is sufficient to be safe
Standing with soft knees is advised so that they can comfortably place the entire back (sacrum to thorax) and the back of the head against the wall.
Propping could still be incorporated if needed
Incorporating additional exercises as a combined effort (such as a semi or full squat or a “w” exercise with the arms)
