Very steep angles significantly change the mechanics of the face pull and begin recruit different muscles in the back, so avoid angles greater than 30-degrees from the horizontal. Very high face pulls can still be useful exercise when you want a hybrid back, trap, and shoulder exercise. When in doubt, experiment with several angles and find which feels the most comfortable for you. If you’re still not sure which cable angle you’ll benefit the most from, either use a standard horizontal cable or vary the angle every two to four weeks.
