In the powerlifting world, the face-pull is a staple. For everyone else who just wants to look good, the face-pull has been all but forgotten. This is a mistake.
While the face-pull isn't an exercise that's going to add slabs of muscles to your frame, what it will do is help offset all the pressing you're doing, while at the same time working the often neglected rear delts, rhomboids, and external rotators. This is going to allow you to continue getting stronger while keeping you healthy in the long run.
When I first approached corrective and performance exercise specialist Paul Chek about writing for Testosterone, his first concern was whether I'd choose to soft-peddle his article. In other words, he was worried that I'd try to "dumb down" his material.
