Hook
You feel the ball jump off the face hot and low, then dive hard to the left. It's the opposite of a slice but somehow feels worse, because hooks run when they land and there's no stopping them. What's happening mechanically is your clubface is closed relative to your swing path at impact. If your club is swinging 5 degrees to the right but your face is pointing 2 degrees to the LEFT of that path, the ball gets right-to-left spin axis tilt and curves hard. The more the face is closed to the path, the more violent the hook.
Why It Matters
The hook is the better player's miss. Beginners slice. As golfers improve, they often overcorrect into hooks, usually by strengthening their grip or learning to swing from the inside without adjusting their release. A hook is actually a sign of progress, it means you've learned to close the face, but you're closing it too much relative to your path. The problem is that hooks are harder to control than slices. A slice curves predictably and loses distance. A hook can snap left without warning, producing the dreaded two-way miss that makes scoring nearly impossible. Fixing a hook requires understanding WHICH of the three causal paths you're on, because the fixes are different and some conventional solutions make certain hooks worse.
Common Misconceptions
A hook is caused by a grip that's too strong
Strong grip is only one of three common causes. AMG's 3D data shows that many hookers actually have a neutral grip but get "stuck" under the plane with an excessively in-to-out path. Others have a fine grip and path but their body stalls, forcing the hands to flip. Each cause has a different fix.
To fix a hook, just weaken your grip
This only works if the grip IS the cause. If your hook comes from being stuck (too shallow), weakening the grip gives you a push-slice instead of fixing the root issue. If your hook comes from a body stall, weakening the grip just changes WHICH kind of miss you hit, not whether you miss.
A hook means you're swinging too much from the inside
An in-to-out path alone doesn't cause hooks. You can swing 8 degrees from the inside and hit a straight push if the face matches the path. The hook happens when the face is closed RELATIVE TO the path. The path might be the problem, the face might be the problem, or both.
Expert Perspectives
Athletic Motion Golf (3D Analysis)
"The hook is primarily caused by getting too shallow/stuck in the downswing. 3D data shows the club dropping too far under plane, creating an excessively in-to-out path that the face can't keep up with."
Monte Scheinblum
"Most hooks are a body rotation problem, not a path problem. When the body stalls, the hands flip and close the face. Fix the rotation and the path takes care of itself."
Rick Shiels (Rick Shiels Golf)
"A strong grip with a natural release will always tend toward hooks. Weaken the grip first, then adjust the release to match."
George Gankas (GG SwingTips)
"Grip changes are band-aids. The real fix is learning to match your release rate to your path. You can play great golf with a strong grip if your body rotation and release are synchronized."
Practice Drills
01 — Body Rotation Through Impact
Focus on rotating your belt buckle to face the target at your finish. Make half-swings where the only thought is "chest to target." This prevents the body stall that forces the hands to flip. If your hook disappears with this focus, your body stall was the cause.
02 — Headcover Path Check
Place a headcover about 8 inches behind the ball and 4 inches inside the target line. If you hit the headcover on the downswing, your path is too far from the inside (stuck/shallow). Practice swinging just outside the headcover. This shallows out the excessively in-to-out path that creates the stuck hook.
03 — One-Knuckle Grip Test
Temporarily weaken your grip until you see only one knuckle on your lead hand. Hit 10 balls. If the hook disappears completely, your grip is the primary cause. If the hook persists or becomes a push-slice, the grip isn't the issue, look at path or body rotation instead. This is a diagnostic drill, not a permanent fix.
