Here's the thread with the pictures of YTWLs:
Correct YTWL?
I really prefer the face pulls done by Bill Hartman in the video in this article:
Push-Ups, Face Pulls, and Shrugs by Bill Hartman and Mike Robertson
Be sure to read this article too; don't just look at the video. Bill discusses proper technique, stretching to maximize effectiveness, and demonstrates the movement. The elbows should be as high as the shoulders (aim the center of the rope handle right at your forehead). The upper arm should not move beyond the scapula. The elbow angle should be as wide as you can get it.
This thread elaborated a bit on this information:

It is also necessary to have adequate thoracic extensibility before this movement can be really effective. So be sure to also be doing some thoracic mobility work such as the foam roller movements shown in I/O and/or the thoracic mobility drill demonstrated by Mike Boyle in
The Essential 8 Mobility Drills.
