How to progress the exercise
In order to have better control of the shoulder stabilizers in this exercise, start performing the exercise with knees and hips bent at 90 degrees (seated position). From there, you can progress to a straight-bodied position, then to a more horizontal position.
Tip: The progression of this exercise will be a lot slower, due to the lack of bigger lat muscle engagement. Due to this, it is better to begin the exercise in a more upright position to better work the smaller shoulder girdle muscles with proper form.
