The "In-to-Out" Path Corridor Drill

Kevin uses both pathpal halves plus a ground rod to create a three-point corridor. The first angled rod is set at 65 degrees on the backswing side to prevent the club from going too far inside — allowing a small amount of inside movement while preventing an excessively flat takeaway. A second rod lays along the ground aligned with the feet as a constant reference for the overall path direction. The third piece is set at 60 degrees on the follow-through side to prevent the club from exiting too far left — training the in-to-out finish that produces draws and eliminates slice-producing exits.

Backswing and follow-through path faults are often connected but independent — a golfer can have a correct backswing and still exit left, or vice versa. By placing separate barriers at both ends of the swing, Kevin's corridor drill ensures that both phases are trained simultaneously rather than assuming one automatically corrects the other. The backswing barrier prevents the inside takeaway that sets up an over-the-top downswing. The follow-through barrier prevents the left exit that is the signature finish of a slice path. Correcting both in one setup is more efficient than addressing each fault in separate sessions.

The ground rod laid along the feet provides a fixed visual reference that anchors both barriers to actual target line direction. Without it, the angled barriers have no spatial context — a golfer can clear the 65 and 60-degree rods but still be misaligned to the target. The ground rod ties the whole corridor to a consistent reference, so path improvements built in the drill translate directly to on-course alignment rather than being practiced in a positional vacuum. Kevin lines it up with his feet, which gives both the swing path and the body position a common directional baseline.

Eric Barlow's drill places a single barrier outside the lead leg to catch a left exit — a one-point, post-impact path corrector for a specific over-the-top fault. Kevin's corridor drill is a three-point system that defines the entire path from backswing through follow-through, making it more comprehensive but also more complex to set up. Barlow's drill is ideal for a golfer who has a clearly identified exit problem and needs a simple, immediate fix. Sprecher's corridor is better suited for golfers who need to understand their full path shape — where the fault originates and where it ends — and want a complete training environment for both ends of the swing.

Kevin specifically recommends it for indoor use — he's based in New York where winter limits outdoor sessions — and the drill is ideally suited to the format. The pathpal requires no ball flight to deliver feedback: the corridor is either cleared or it isn't, so slow-motion and rehearsal swings produce the same motor learning benefit as full shots. The compact physical footprint of the three-unit setup means it works in a simulator bay, a basement, or any space with enough room for a half-swing rehearsal. Kevin notes this is one of his primary reasons for using the pathpal daily with students during the winter months.
