This happened to me. The bigger I got the more I had to force my elbows back. This started creating issues.
In general I am of the opinion that on BTNs as long as you don't take the arm past parallel to the ground you're pretty darn safe. Again, mileage varies. I was more flexible in my youth and could take it deeper.
Like any other exercise, common sense should be utilized.
i dont do anything behind the neck. My shoulders dont even like when i hold the bar to squat anymore. they get mad.
