Loading
Loading refers to the act of storing energy during the backswing by turning the upper body against a stable lower half, so that power can be released into the ball on the downswing.
What is loading in golf?
Golfers borrow the word from physics. When a player “loads,” they coil the shoulders and torso against the resistance of the hips and legs during the backswing, building tension in the muscles of the core, hips, and glutes. That stored tension is released in the downswing, where it becomes clubhead speed (the speed of the club head at impact).
The term shows up constantly in golf broadcasts and lessons because loading is where distance comes from. A swing with no load is an arms-only swing, and it produces weak contact no matter how hard the player swings. Todd Anderson, director of instruction at the PGA Tour Performance Center at TPC Sawgrass, describes the concept as “load and explode”: the body coils into the trail side (the side farther from the target, the right side for a right-handed golfer) going back, then drives toward the target coming down.
Loading involves the whole body, though the pieces play different roles. The lower body stays stable and accepts pressure into the trail foot. The upper body rotates against it. The wrists hinge, adding a second store of energy at the top of the swing. Jim McLean’s X-Factor research, published in Golf Magazine in 1992, put numbers on the coil: powerful players turn their shoulders around 90 degrees while their hips turn closer to 45, and that gap between the two is where much of the stored power lives.
How loading works
Picture a spring being compressed. At address, the golfer is neutral. As the backswing begins, pressure builds under the trail foot while the shoulders turn further than the hips. By the top of the swing, the torso is wound against the lower body like a coiled spring, the wrists are hinged, and the trail leg is braced rather than straightened or swayed.
A loaded position is easy to recognize on video. The player’s back faces the target, the head has stayed roughly centered, and the trail knee still has flex. What follows is the unload: the lower body shifts and rotates toward the target first, and the stored energy travels up through the hips and torso, out along the arms, and into the club. According to PGA professional James Parker, tour players arrive at impact with 80 to 95 percent of their weight over the lead leg, which shows how completely the load gets transferred.
Pressure-plate data has refined the picture in recent years. Instructors at Golf.com, using force plates to measure ground pressure during the swing, found that strong ball-strikers build trail-foot pressure early in the backswing, then let it ease before the top, which puts them in position to move toward the target on time. Loading, in other words, peaks earlier in the swing than most people assume.
Loading vs. lag vs. weight shift
These three terms get tangled together in golf commentary, and they describe different things. Loading happens in the backswing. Lag, as defined by the wrist-sensor company HackMotion, is the angle between the lead forearm and the club shaft that is retained during the downswing. Weight shift describes how mass and pressure move between the feet across the whole swing.
| Term | When it happens | What it describes |
| Loading | Backswing | Storing energy by coiling the body against a stable lower half |
| Lag | Downswing | The retained angle between the lead forearm and the club shaft before release |
| Weight shift | Entire swing | Movement of pressure from the trail foot to the lead foot |
A related variation is float loading, a term from Homer Kelley’s 1969 book The Golfing Machine. The idea: instead of completing the wrist hinge in the backswing, the player delays it until the start of the downswing. Bubba Watson swings this way.
Common misconceptions about loading
The most common mistake is treating loading as a lateral move. Sliding the hips away from the target feels like loading, but it moves the body off the ball and drains the coil of its tension. Analysis from Athletic Motion Golf, reported by MyGolfSpy, found that modern tour players shift within a window of roughly one to two inches, about the width of a golf ball. The load comes from rotation against a braced trail leg, not from movement away from the target.
Another misunderstanding: more trail-side pressure at the top means a bigger load. The pressure-plate findings above suggest the opposite. Players who hang on their trail side late in the backswing struggle to get back to their lead side in time for impact.
Some golfers also assume loading requires physical strength. It doesn’t. The energy comes from the stretch between upper and lower body, which is why players with smooth, unhurried swings can still produce high clubhead speeds.

- Slide — Excessive lateral lower-body movement toward the target in the downswing.
- Early extension — A fault where the hips thrust toward the ball during the downswing.
- Sway — Excessive lateral hip movement away from the target on the backswing.
- Over the top — A downswing fault where the club moves outward, often causing slices.
Frequently Asked Questions
Is loading the same as swaying?
No. Swaying means the hips or head slide laterally away from the target, while loading is rotation against a stable lower body. A sway usually drains the load.
Does loading only apply to the driver?
No. Every full swing involves loading. The driver swing shows it most clearly because the swing is longest and distance matters most, but irons and wedges load the same way at smaller scale.
What does it mean to load the club or load the shaft?
It refers to the flex the shaft takes on during the transition from backswing to downswing, when the club head momentarily bends the shaft backward before releasing forward through impact.
Where should a golfer feel the load?
Most players feel it as tension through the core, the trail glute, and the inside of the trail leg at the top of the backswing.
