The Thesis
The 'Transition' is that fleeting, magical millisecond where the backswing ends and the downswing begins. It is the moment of truth. If you rush it, you ruin it. If you sequence it correctly, you unleash effortless power.
Most amateurs destroy their swing right here. They finish the backswing and immediately lurch at the ball with their shoulders and hands (the 'Over the Top' move).
Tom Watson calls this the "power move." He defines it as Separation: "The lower body starts forward when the upper body is still going back." This stretch creates the torque that drives the ball.
The Conflict
How do we change direction? The masters offer different visualizations for the same engine.
The Hip Slide (Hogan):
Ben Hogan, in Five Lessons, preaches the Hip-Driven Lateral Slide. He is adamant: 'The hips initiate the downswing.' He describes an elastic tension where the hips turn back to the left while the shoulders are still turning right. 'The hips must slide laterally toward the target,' dragging the upper body with them.
The Gravity Drop (Tiger Woods):
Tiger Woods offers a smoother, more vertical visualization. He advocates: "Let Gravity Rule." Instead of aggressively sliding, Tiger starts by "shifting my weight easily back to my left side, and then letting my arms 'fall' downward in front of my chest." He warns that if the shoulders unwind too fast, they get ahead of the arms—a common amateur killer.
The "Lazy" Pause (Tom Watson):
Watson focuses on rhythm. He sees the transition not as a violent change of direction, but as a blending of forces. He advises golfers to "feel lazy at the top." He argues that a slight pause allows the lower body to lead, creating the necessary separation without the "jerk" that ruins accuracy.
The Conflict: Hogan wants an aggressive lateral slide. Woods wants a gravity-fed drop. Watson wants a rhythmic pause.
The Synthesis (Best Practice)
To reconcile Hogan's power with Woods's efficiency and Watson's rhythm, we adopt the 'Squat, Drop, and Snap.'
Science and modern biomechanics tell us that to generate rotational speed, we must first use Ground Reaction Force. We don't just slide left; we push down to snap up.
The Best Practice:
1. The Trigger (The Shift)
The downswing begins from the ground up. As Woods says, "The sequence of motion is from the ground up." Shift your weight to the left foot. Watson visualizes this as "The left heel returns to the ground."
2. The Move (The Squat & Drop)
Instead of spinning your shoulders (Over the Top), feel like you are sitting down into a chair. Simultaneously, let your arms "fall" straight down as Tiger suggests. This keeps the club on plane and prevents the "stuck" position Jim Hardy warns against.

3. The Release (The Snap)
This is Tiger's secret power source. Once you have shifted and squatted, you must Snap the left leg straight. Tiger writes: "I straighten that left leg as quickly as I can on the through-swing." This snapping motion acts as a brake for the lower body, which catapults the clubhead through the ball at maximum speed.
The Drill
The "Step-Through" Drill
Goal: To program the lower-body-first sequence (Separation) and feel the ground force.
The Setup:
Stand with your feet together, holding a club across your chest. Make a backswing turn.

The Action:
- 1. Step your left foot out to a normal stance width while your shoulders are still turned back (Creating Separation).
- 2. Squat onto that planted left foot.
- 3. Snap the left leg straight to turn the hips through to the finish.

The Lesson:
You cannot throw your shoulders "over the top" if your left foot is stepping forward while your back is turned. This drill forces the lower body to lead. As Bobby Jones wrote, "It is always easier to continue a motion than to begin it." By keeping the legs moving, the transition becomes a flow, not a jerk.
