Final answer:
In the yoga pose chaturanga, the elbows should be bent at a 90-degree angle for proper form and to prevent injury.
Step-by-step explanation:
In chaturanga, an asana or pose in yoga, the elbows should be bent at a 90-degree angle when viewed from the side. This is important to maintain proper form and avoid injury during the practice. It is noteworthy to mention that in the anatomical position, there is a natural carrying angle due to the lateral deviation of the forearm, which ranges from 5 to 15 degrees. However, in the chaturanga posture specifically, the emphasis is on keeping the upper arms parallel to the floor, which necessitates the 90-degree bend in the elbow.
