We've all seen the chicken wing squat - lifters' with their elbows cocked back almost parallel to the ground. We know it doesn't look "right." But is it a problem? And if so, how do we fix it?
First, it is an issue. It's any combination of tight lats, tight pecs, and a tight sub scap. It causes lifters to lose (or even never generate) proper tension in their mid and upper back before a squat. And the result is the ol' good morning out of the hole.
The fix? Some simple mobility work. The following is by no means and end all be all, but a simple series of stretches that have addressed the problem for me.
In order, for your viewing pleasure...
