Final answer:
If a student can't reach the foot in the Extended Side Angle, using a block or resting the forearm on the thigh can provide necessary support while maintaining pose integrity.
Step-by-step explanation:
In the Extended Side Angle pose, if the hand cannot extend to the outer edge of the foot, a modification can be made by placing the hand on a block, or by resting the forearm on the thigh of the bent leg. This modification maintains the integrity of the pose while accommodating limited flexibility, helping the practitioner to keep the torso long and the chest open. It is important to keep alignment and avoid collapsing the upper body down onto the thigh, so using a block or the forearm creates the necessary support.
