Sway
A sway is excessive side-to-side movement of a golfer’s body away from the target during the backswing, with the hips sliding sideways instead of turning.
What is a sway in golf?
A sway is a swing fault. The Titleist Performance Institute (TPI) defines it as any excessive lateral movement of the lower body away from the target during the backswing that pushes the golfer’s weight to the outside of the trail foot (the foot farther from the target, so the right foot for a right-handed player).
In a sound backswing, the hips rotate while staying roughly centered, coiling the upper body against a stable lower body. A golfer who sways skips the coil. The hips drift sideways toward the trail foot, the weight rolls to the outside of that foot, and the body ends up leaning away from the ball rather than turning behind it.
The term comes up constantly in lessons and TV commentary because it is one of the most commonly diagnosed faults in amateur golf. Understanding it also helps make sense of instruction phrases like weight shift and re-centering.
How a sway affects the swing
Every golf swing has a low point, the spot where the clubhead reaches the bottom of its arc. For solid contact with an iron, that low point needs to sit just in front of the ball. Golf Distillery notes that sliding the hips back and forth makes it hard to return the low point to the same spot twice, which is why swaying golfers hit so many fat and thin shots.
Power suffers too. TPI compares a good backswing to a baseball batter digging in against the back leg: the batter coils around that leg, then drives off it. A golfer who has swayed onto the outside of the trail foot has no stable platform to push from, so the downswing starts weakly and out of sequence.
How much sideways movement is normal?
Less than most golfers think. GOLFTEC, drawing on measurements from the 1.5 million lessons its coaches have taught, found that the average PGA Tour player’s hips move just 0.3 inches away from the target by the time the shaft reaches parallel in the backswing, and the shoulders move 0.1 inches. From the top of the backswing to impact, tour players then shift their hips about 3 inches toward the target.
Broadcast data tells the same story. When CBS analyzed Ludvig Åberg’s swing with Optimotion technology in 2024, analyst Trevor Immelman pointed out that Åberg’s hips move just over an inch away from the target going back, then sit 2 inches toward the target at impact, slightly less lateral motion than the tour average.
Some sideways drift is normal, in other words. PGA professional Mark Komives puts the common range at 1 to 2 inches of backswing movement and says golfers get into trouble when they move more than a few inches, or when they fail to re-center before the downswing. The line between a normal shift and a sway is measured in inches.
Sway vs. slide and other faults
Golfers often mix up the sway with two related faults. The Golf Fitness Association of America draws the line by timing: excessive lateral movement in the backswing is a sway, while the same movement in the downswing is a slide.
| Fault | When it happens | Direction of movement | Typical result |
|---|---|---|---|
| Sway | Backswing | Away from the target | Weight on the outside of the trail foot, fat and thin contact, lost power |
| Slide | Downswing | Toward the target | Hips outrun the upper body, club gets stuck behind, blocks and hooks |
| Reverse pivot | Backswing | Upper body tilts toward the target | Weak contact and added strain on the lower back |
The distinction matters because the fixes differ. A player who sways needs a more stable trail side, while a player who slides needs the lead side to firm up and rotate. Diagnosing the wrong one wastes practice time.
What causes a sway
Physical limitations sit behind many sways. TPI’s Dr. Greg Rose cites research showing that golfers with more than 45 degrees of internal rotation in the trail hip sway far less often, and place less stress on the lower back, than golfers who lack that mobility. When the hip joint cannot rotate, the body moves sideways instead, because that is the only motion left available.
Weak gluteal muscles contribute as well. TPI identifies the glute medius, a muscle on the side of the hip, as the main stabilizer that keeps the trail hip from drifting outward during the coil.
Setup choices and misunderstandings play a part too. PGA Master Professional Dean Alexander warns that a stance much wider than hip width makes it hard to shift weight without swaying. And many golfers simply misread the phrase “weight transfer” as an instruction to push the whole body sideways, when good players transfer pressure through rotation.

- Over the top — A downswing fault where the club moves outward, often causing slices.
- Hip turn — Rotation of the hips that powers the golf swing.
- Early extension — A fault where the hips thrust toward the ball during the downswing.
- Reverse pivot — A weight-shift fault that leaves weight on the lead side at the top.
- Shoulder turn — Rotation of the shoulders during the backswing to build coil.
Frequently Asked Questions
Is any amount of sway bad?
No. Small lateral movement appears in nearly every tour swing, and Åberg’s roughly 1 inch going back is typical of elite players. The fault is excess. Movement beyond a few inches, or a shift the golfer never re-centers, is where problems start.
Is a sway the same as a slide?
No. A sway happens in the backswing as the body moves away from the target, while a slide is a downswing fault in the opposite direction. A golfer can have one without the other.
How can a golfer tell if they sway?
Common signs include weight rolling to the outside of the trail foot at the top of the backswing and the hips drifting past the trail foot on video. Face-on video makes it easy to spot: the belt buckle moves sideways instead of turning.
Can a sway hurt the body?
The movement itself is not dangerous, but TPI’s research links the restricted hip rotation that drives most sways to added stress on the lower back.
