Equipment Needed
Step-by-Step Instructions
Tuck a folded glove (or headcover) under your lead armpit (left armpit for right-handed golfers). It should stay there by pinching your upper arm against your chest lightly.
Take some practice swings with an iron, focusing on keeping the glove in place. This means your arms and body are moving in unison rather than separately.
Hit balls with the glove under your arm. If your lead arm separates (flaps) through impact or on the follow-through, the glove will fall, indicating a loss of connection.
Aim to strike a series of iron shots without the glove falling. This will ensure you're keeping your lead arm extended and your upper body rotating properly through impact.
Professional Endorsement
Many players like Rickie Fowler have been seen practicing with a glove under their lead arm to stay connected. Rory McIlroy also uses a similar drill to maintain his swing structure and prevent his left arm from lifting away.
