The last person who easily hit a hook shot from the three-point line distance and left a video of it was Wilt Chamberlain.
To showcase his incredible upper body strength, he performed a long-distance hook shot ability in front of the camera.
Of course, Chamberlain only used this move during practice for fun, as it wouldn't have been practical in a real game.
If he had the ability to do so in games, his free throw percentage wouldn't have been so low, he could just hook it directly from the free throw line.
Gan Guoyang was practicing three-point hook shots not for use in games, but to improve the stability and feel of his hook shot.
In the intense environment of a game, shooting and hook shots generally don't give you time to aim and think; you rely on muscle memory built up day by day.
Following Dr. Ogilvy's instructions, while performing visualization training Gan Guoyang also had to further strengthen his muscle memory during practice.
