Rory talking trail arm structure 🦻 Amazing clip from Ikd_golf here with Rory talking about some of his swing thoughts recently. I have no idea if this was on his mind during this week at The Open, but we’ve seen him work on arm structure a lot in the past. Love seeing players talk trail arm - it’s fascinating, super important, and wildly overlooked! . . . . #rorymcilroy #pgatour #theopen #golfswingtips
