#729 Why Everything You’ve Been Taught About Golf “Lag” is Likely Wrong

For generations, golfers have tried to “hold lag”—pulling the handle down, increasing grip pressure, and deliberately preserving the wrist angle. Modern biomechanics shows why this approach can actually reduce speed. Lag is not something you create. It is something that happens. The sharp angle between the lead arm and club shaft seen in elite players is primarily a result of movement, sequencing, and inertia. As the body changes direction, the clubhead’s mass resists that change and naturally trails behind. An efficient downswing follows a ground-up sequence: Pelvis → Chest → Arms → Club But acceleration is only half the story. Each proximal segment must also decelerate at the right time, allowing energy to transfer outward. This creates the whip-like action responsible for clubhead speed. The Secret: Temporal Separation The downswing begins before the club has completely finished the backswing. The lower body starts moving toward the target while the club is still travelling back. This creates mechanical stretch across the kinetic chain. The delay is not produced by holding the wrists—it emerges because the body starts earlier while the club responds later. Shift – Brake – Press Ground Reaction Forces help organize the downswing: Shift: Pressure moves toward the target while ankle, knee, and hip maintain flexion. Brake/Torque: Lateral motion stabilizes as rotational speed increases. Press: Vertical force and extension contribute to the final acceleration. One major speed leak occurs when golfers straighten or “jump” too early. The pelvis rises prematurely, the arms become active, and the club often casts. Why Tension Kills Lag Trying to hold the angle with stiff wrists and high grip pressure turns a dynamic system into a rigid lever. Efficient players maintain structure without unnecessary tension, allowing the arms and club to respond naturally to body rotation and inertia. Measuring the Cause WatchItGolf helps coaches move beyond static video positions by analyzing segment sequence, speed gains, deceleration patterns, ground interaction, and lower-body stability. Instead of treating the symptom—the visible wrist angle—we can train the cause: how energy moves through the body. Don’t hold the lag. Build the sequence. Store the energy. Transfer the speed. Release the club. ⁠ My Blog⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠ ⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ The Explainer ⁠⁠⁠⁠ ⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ ⁠www.ecoach360.com⁠ ⁠
