Sort your setup firstRounded shoulders and closed alignment at address can predispose you to an inside takeaway before you’ve even moved the club, so check your posture, shoulder position and hip hinge before each swing.
Sync your body and club togetherIf your arms and club outrace your chest in the takeaway, the club whips behind you immediately — use the belly drill to feel your bigger muscles initiating the movement so the club stays in front of you.
Use an alignment rod to check your pathPlacing a rod at the angle of your swing plane gives you instant feedback on whether the club is moving inside too early, and attaching a rod parallel to your grip shows you straight away if your hands are twisting the club off track.
