PGA coach Alex Elliott explains why maintaining 'levels'—consistent head and body height—is the secret to driving distance and accuracy. He demonstrates how dropping the head in the backswing causes inconsistent strikes and loss of power, providing three specific drills (Wall Drill, Gear Drill, and Feet Together) to fix it.
Dropping your head in the backswing often leads to hitting the top of the driver face or overcompensating by leaning back.
Hitting the driver 'on the up' requires a consistent low point in the swing arc, which is destroyed by changing your height.
The 'Gear Drill' helps translate a practice feel into a full-speed swing by incrementally increasing intensity.
A narrow stance (Feet Together Drill) exposes balance flaws and prevents the 'dipping' motion that kills driver consistency.
Hitting out of the center of the face is more important for distance than raw swing speed alone.
