Shanks are the worst. There’s nothing more embarrassing than having your golf ball rocket away from you at a right angle.
You greatly increase your chance of hitting a shank shot if you stand to close to the golf ball or shift your weight to your left foot before impact. Either of those situations will cause the hosel of the club to hit your ball and produce a shank.
The easy way to avoid these is to setup evenly and make sure there’s about a fist length of space between your grip and your body when you’re holding your golf club.
A lot of people will recommend practice drills with shafts and body placement to cure a shank but I think you’re better off concentrating on how close you are to the ball when you swing. That’s probably the root of the problem the majority of the time.
