Connection
Also known as: connected swing, body-arm sync
Connection means the arms and body move together, so the arms never get ahead of or behind the body's rotation. It keeps the arc and face delivery consistent.
In the golf swing, connection refers to the relationship between the arms and the body throughout the swing. Specifically, it is whether the arms move in unison with the torso rotation rather than independently. In a "connected" swing, the lead arm stays in contact or near-contact with the chest during the backswing and downswing. This ensures that body rotation directly drives arm speed. In a "disconnected" swing, the arms separate from the body and swing independently of the core. The power link between the body's rotation and the club is lost.
The concept of connection comes primarily from Ben Hogan's writings and subsequent interpretation by instruction pioneers like Jimmy Ballard and others. The practical teaching tool is the "glove under the armpit" drill. The golfer places a glove or headcover between the lead arm and chest and keeps it there through the swing. If it falls, the arm has separated. Modern interpretations have evolved this concept. The arms do not literally need to press against the chest throughout the swing, which would restrict it. But they should move in harmony with the torso rotation rather than independently of it.
Disconnection is one of the most common power leaks and a contributor to several swing faults. When the arms separate from the body, they must generate their own speed rather than being powered by the body's rotation. This is inherently less efficient and more timing-dependent. Disconnection in the downswing also frequently produces an over-the-top club path. The arms swing out and away from the body to generate speed, rather than staying inside and being propelled by rotation.
For an immediate connection drill: hit chip shots with a glove tucked under your lead armpit and try to keep it from falling for the entire chip — this short-game version of the connection drill teaches the feel of arms-and-body moving together without the full demands of a complete swing.
To develop connection at full speed, practice with an "arm-connected" feel at 80% effort until the pattern is ingrained, then gradually increase speed while monitoring whether the arm-body relationship is maintained. Most disconnection happens when swing speed increases, and building connection at moderate speeds before adding effort produces more durable improvement.
Example
A player who keeps the lead arm close to the chest throughout the swing is "connected" — the club arc follows the body turn reliably.
How it shows up on video
From a face-on camera angle, connection is visible as the lead arm staying close to or against the chest throughout the backswing and early downswing. A disconnected swing shows the lead arm lifting away from the chest in the downswing. A gap appearing between the arm and the torso — and the arms swinging outward rather than being driven by body rotation. From a down-the-line angle, disconnection often shows as the trail arm "flying" (the trail elbow lifting away from the body in the backswing) and the arms crossing outside the downswing plane.
Common mistakes
- Confusing connection with restriction — squeezing the arms against the chest throughout the swing creates tension and limits range of motion. Connection is about harmonious movement, not constant physical contact between arms and chest.
- Focusing on the trail arm connection rather than the lead arm. Most connection drills emphasize the lead arm. But the trail arm's "flying elbow" in the backswing is an equally valid connection issue that contributes to over-the-top paths.
- Achieving connection only on the backswing but disconnecting in the downswing. Many golfers can maintain connection in the backswing but immediately separate at the top when they initiate the downswing with the arms. The critical moment to be connected is in the early downswing.
- Assuming disconnection is always bad — some elite players (Jim Furyk, for example) have unorthodox arm movements that appear disconnected but are highly consistent. Addressing connection is most important when inconsistency or over-the-top path is the presenting problem.
In SwingVantage Motion Lab
Motion Lab does not measure a gap between your lead arm and chest. In Visual Proof it does show each arm's angle at each P1–P10 position it can find. P2, P6 and P8 need the club, so it never shows them. With the camera view set to down-the-line, it also shows how far your hands sit from your lead ankle. Those describe the arms but are not a connection score. Film face-on and pause in the downswing to see whether the lead arm stays on your chest.

- TakeawayThe takeaway is the first movement of the club away from the ball. Where and how the club moves in the first 18–24 inches often sets the backswing's shape.
- Arm SwingThe arm swing is the movement of the arms across and around the body during the golf swing. This must coordinate with body rotation to produce a consistent, powerful arc.
- Shoulder TurnShoulder turn is the rotation of the upper back (thoracic spine) and shoulders during the backswing. A full turn, near 90°, is the main source of swing arc and coil.
