Petra Yoga

Can you spot the difference in these two photos:

In the top picture, the student is rolling the shoulders downwards, thus creating a big strain on the muscles of the rotator cuff.  By doing the pose in such a way over a period of time, one puts these muscles at risk of a permanent injury.

The bottom picture shows a corrected press-up where the shoulder does not go below the elbow in respect to the floor, which is a correct and much safer way of doing this pose.
