Connection
Also known as: connected swing, body-arm sync
Connection is keeping the arms and body moving together during the swing. As a result, the arms never get ahead of or behind the body's rotation, maintaining a consistent arc and face delivery.
Connection in the golf swing refers to the relationship between the arms and the body throughout the swing. This means in particular, whether the arms move in coordinated unison with the torso rotation rather than on its own. A "connected" swing has the lead arm maintaining contact or near-contact with the chest during the backswing and downswing, ensuring that body rotation directly drives arm speed. A "disconnected" swing has the arms separating from the body, swinging on its own of the core, and losing the power link between the body's rotation and the club.
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. This means placing a glove or headcover between the lead arm and chest and keeping it there through the swing. If it falls, the arm has separated. Modern interpretations have evolved this concept. This means the arms do not literally need to press against the chest throughout the swing (which would restrict the swing). But they should move in harmony with the torso rotation rather than on its own 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. This is. This is because 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. This means hit chip shots with a glove tucked under your lead armpit and try to keep it from falling for the entire chip. This means 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. At the same time, monitoring whether the arm-body relationship is maintained. This means 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. This means a gap appearing between the arm and the torso. This means 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. This means 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. This means 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 uneven results or over-the-top path is the presenting problem.
In SwingVantage Motion Lab
SwingVantage observes connection patterns from face-on and down-the-line video by tracking the spatial relationship between the lead arm and the torso throughout the swing. The system can identify arm-body separation in the downswing. This means especially the trait "gap" between the arm and chest. This means and label these observations with confidence based on video quality and whether the body-arm relationship is visible throughout the swing.

- 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 determines the rest of the backswing 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 thoracic spine and shoulders during the backswing. A full shoulder turn (near 90°) is the primary source of swing arc and coil — the engine of a powerful backswing.
