Swing sequence: Zach Johnson

The shaft is in a great position - pointing to his belt line - which signifies that Zach is standing the proper distance from the ball and in good balance. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

FAVORITE MOVE No. 1: Zach’s hands move in while the clubhead stays out, creating the perfect on-plane backswing (i.e., shaft pointing to an extended version of the target line). (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

Zach’s hands still remain inside the clubhead. His hips have turned approximately half as much as his shoulders, which sets up a powerful coil. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

There’s tremendous depth to Zach’s backswing here, as evidenced by his hands being even with his right bicep. This is another checkpoint for the hands being on plane. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

FAVORITE MOVE No. 2: The left arm is on the same plane as his shoulders, and his right elbow points to the ground, which is textbook. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

Zach’s hands and arms start to make a beeline for the ball before the hips begin to clear. This is referred to as straight-line acceleration. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

FAVORITE MOVE No. 3: By the time Zach’s knees are square, his hands are already down to his waist, which represents perfect sequencing. The shaft on the forearm equates to maximum leverage. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

At impact, Zach’s shoulders are square to the target and his right arm and club shaft are in a straight line, two moves that scream accuracy. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

Zach remains in his forward tilt (i.e., inclination to the ground) well into his follow-through, another key to consistently driving the ball in the fairway. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)

Note how relaxed Zach’s arms are—not extended out or too stiff—and how balanced he is at the finish, both signs of an accurate, on-plane swing. (Analysis: GCA lead coach Mike Bender; photo: Fred Vuich)
