Bryson DeChambeau / Golf Swing Before He Got Big (2016)

There is the "1" swing move he has never changed and says he never will: The one thing he hasn't changed is his wrist position at setup. He uses ulnar deviation: left wrist lined up with his forearm and fingers pointing down. Draw or fade, this arrangement sets the radius of his swing so his joints have the correct amount of space to move. It’s something that can help you too.

As you swing down from the top, centrifugal force pulls your left arm straight, so that by the time you reach impact, your arm and the shaft form a straight(ish) line. That’s why he sets up with ulnar deviation. Why the majority of golfers set up with their arm and shaft at an angle is beyond his understanding. It’s just one more compensation less to worry about!
