Methodology

Hypothesis → Measure → Prescribe → Verify

The traditional golf lesson relies heavily on a coach's eye and ambiguous terminology. "Get wider," "drop it in the slot," "clear your hips." These phrases mean entirely different things to different players.

We reject this approach. The golf swing is an applied physics problem. The clubhead must arrive at the ball with a specific orientation, velocity, and trajectory to produce a desired flight. The body is the engine that delivers that clubhead.

Core Principles

1. Ground Reaction Forces (GRF)

Power originates from the ground. How you press into the earth dictates how you rotate and how much force you can generate. We measure vertical, lateral, and rotational forces using dual force plates.

• Vertical Force: Typically peaks just before impact in elite players, allowing the lead leg to act as a post for rotation.
• Lateral Force: Moves the center of mass away from the target in the backswing and towards the target in transition.

2. The Kinematic Sequence

The efficient transfer of energy from the ground to the clubhead. It must happen in a specific order: Pelvis → Thorax → Lead Arm → Club.

If the thorax fires before the pelvis (commonly known as "coming over the top" or casting), speed is lost, and swing path is compromised. We use 3D motion capture to graph rotational velocities and ensure peak speeds occur in the correct sequence.

3. Impact Geometry

Ball flight is dictated by the laws of physics at the moment of impact. Specifically, the relationship between Club Path and Club Face Angle relative to that path.

Face to Path	Resulting Shot (RH Golfer)
Closed (Face points left of Path)	Draw / Hook
Open (Face points right of Path)	Fade / Slice
Square (Face = Path)	Straight Push/Pull/Target
