Look at 4 things. Watch your head. You are losing your spine angle taking the club back (Standing up). Look at the club on the backswing. It is off plane (taking the club too far outside). Look at the video. It should stay on the inside line not the outside line. Look at where your hands are at address and where they at impact. You have changed the lie of the club because you are off plane and changed the spine angle. Lastly, look at your butt at the start of the swing and at the end. Practice with a garbage can behind you and leave your butt on it thru the swing as you turn. Dont move forward which changes the swingplane/path.
