Standing too close is quietly costing you clean contact.
Nobody talks about this one but it shows up constantly. If you're too close to the ball at address, your arms have nowhere to go through impact except up and in. So that's exactly what they do. The radius shortens, the circle pulls away from the ground, and you thin it. The fix isn't complicated. You need enough space at setup that when you rotate through and push to the front side, your arms can still reach the ball and the ground without standing up or pulling in to manage the gap. Stretch at setup. Bow down with long arms and let them hang naturally. That's your grip position. From there you've got room to actually swing. It's not about swinging differently. It's about giving yourself the space to swing correctly.
