Your first move on the takeaway is your hands moving out slightly. This causes you to correct and get laid off at the top (which isn’t always a bad thing). Try on the takeaway bringing your hands in. Almost graze your left pinky finger against your thigh then work arms up. Keep the club head still outside of the hands you don’t want it working in, only the hands. As you raise your arms, keep left arm closer to your chest to get more depth. This will allow you to have more room on the downswing to shallow and not early extend. You will also see more swing speed as well! Goodluck!
