What Is a Strong Grip and Why Does It Cause Hooks?
What "strong grip" means
"Strong" here has nothing to do with muscle or squeezing harder (that's grip pressure, a different thing). It refers to the rotation of your hands on the handle. In a strong grip, for a right-hander, both hands are turned to the right: you'll see 3 or more knuckles on your lead hand when you look down, and the "V's" formed by thumb and forefinger point outside your right shoulder.
David Leadbetter defines a neutral grip as one where you see between 2 and 2.5 knuckles of the lead hand and the V's point toward the right shoulder/ear area. Anything rotated further to the right of that moves into strong-grip territory.
Why a strong grip closes the face
The geometry is simple: if you rotate your hands to the right at address and then, at impact, your hands tend to return to their natural neutral position, the clubface arrives closed (pointing left of target). That closed face is what produces the hook.
And here's the number that matters: according to TrackMan's ball flight laws, with the driver the ball starts roughly 85% toward where the face points at impact and only about 15% toward the path. The face controls both the start direction and the curve. A face that's closed relative to the path = a ball that curves left. That's the mechanism behind the hook.
At Birdia we analyze the video of your swing and your ball flight precisely to separate these causes: if the ball starts straight but then hooks away, the number-one suspect is the face at impact — and the grip is the first thing we check.
A strong grip isn't always bad
Ben Hogan is the classic example of the opposite: he fought the hook his entire career and weakened his grip as part of his "secret" to get rid of it. But that doesn't make a strong grip a universal mistake. Many players who tend to leave the face open (slice) improve by strengthening their grip.
The right question isn't "is my grip strong?" but "is my strong grip compatible with what my hands do at impact?" If you hook consistently, your grip is delivering the face more closed than your swing can compensate for. That's when it's worth neutralizing it.
How to check it yourself
Set up at address with your usual grip and look down: count the visible knuckles on your top hand. If you see 3 or more and you hook, try rotating both hands slightly to the left until you see 2–2.5 knuckles (Leadbetter's neutral range). Make smooth swings and watch the curve. A grip change feels incredibly weird the first few days — that's normal, don't bail on it after three shots.

Frequently asked questions
Does a strong grip give me more distance?
Not necessarily. A strong grip can help square the face and cut down a slice, and getting rid of a slice usually does add distance because the shot stops bleeding energy into the curve. But the grip alone doesn't generate clubhead speed — that comes from sequencing and lag. If you're chasing yards, don't force the grip: adjust it only to control the face.
How do I know if my hook comes from the grip or the path?
Watch where the ball starts. Per TrackMan's ball flight laws, if the ball starts right of target and then curves hard left, your path is in-to-out and the face is closed relative to it: that's the classic hook pattern. If it starts straight and falls left, the closed face is the dominant factor. At Birdia we cross-reference video and ball flight to tell you which one weighs more in your case.
Will weakening my grip suddenly make me slice?
Yes, that's a real risk if you jump from one extreme to the other all at once. Change gradually: rotate your hands toward neutral (2–2.5 knuckles) little by little and hit balls until the new position stops feeling strange before you turn any further. A sudden swing from strong to weak usually leaves the face too open and the opposite slice shows up.
