I understand the frustration of being to hit a decent drive and now you feel like you’ve lost that ability. It will be back, but better and easier in the near future.
We worked on the shoulder pivot and the ankle pivot. These initiate the swing in different directions. We also worked on keeping your arms more extended, the clubface square at impact, avoid flipping and scooping by creating lag in your clubhead, and several elements to overcome you hitting left of the target line.
I recommended you focus on the shoulder and ankle pivot avoiding dipping your lead [left] leg during the backswing.
Also, recommended you practice creating lag with your clubhead at home several times a day so that your mind can help cement your muscle memory of this feeling.
I've spent an extra amount of time on the images below describing what I see and what I recommend. In total, at least 2 hours to convert the images to slow motion, freeze frames, analyzing what I see and adding the descriptions for you to read.
I recommend you spend a similar amount of time studying them and more time on the range practicing before you can benefit from another lesson, but that's up to you. Just don't want to waste your time and money, but more than happy to see you anytime.
I've included this photo of Tiger Woods that demonstrates the pro-look at the top of his swing. The left leg is in a straight line with his arms without dipping or bending forward. You can tell that he has a maximum twist with a lot of resistance to build torque going on in this leg.
Tiger's weight is well shifted to his back leg [right one] and his body is fully torque ready to begin his downswing.
Notice also that his arms are fully extended holding the club well above his head and the clubhead stays behind him and does not cross over toward the target line...in other words...parallel to the target line.
He's a pretty good golfer to copy, but since you have little interest in turning pro you can give yourself a little break on trying to look exactly like his style.
We’re employing the alignment rod to check all parts of your body to be sure they are square to the target line. There is an issue with your shoulders being open to the target. This is because your right shoulder pushes forward and this pivots your upper body to an open position. Both shoulders must to be equally visible at address to avoid this misalignment.
This is the same video above in slow motion. The freeze frame at the top shows good extension of your left arm although the wrist is slightly cupped, and this is because your right elbow has moved away from your upper body. To flatten your wrist the right elbow must point to the ground. This is also often called a flying elbow or chicken wing. Just think about keeping your elbow as close together as possible…like a great relationship…don’t let that elbow float away from the other one.
In this video, you have nice tempo, but the downswing is a little too slow because there is very little lag in the clubhead. But the damage comes from an open clubface at impact. You can see this better in the slow-motion version below.
There are several freeze frames in this slow-motion version of the above video. The top of the swing shows a fairly straight left arm with a cupped wrist due to the flying elbow. The next freeze frames demonstrates that the clubhead is fully released before ball impact [notice that the left arm and hand is in a straight line with the club shaft …this is how you can tell all the power is already released]. The third freeze frames demonstrates an open clubface after impact so this ball undoubtedly flew to the right after impact. There is a shadow below the clubface, so look just above that to see the toe edge of your clubhead.
This video is swinging your driver. At the top of your swing the driver crosses over your shoulder and settles to the right of your target line. The club shaft should be parallel to your target line here. Then at impact the clubface is really open. You can see this better in the slow-motion version below.
Slow-motion version of the above video with two freeze frames. At the top you can see the clubhead crossing over your shoulder to the right of your target line and at the bottom, at impact, the club face is open…in fact, the club face is open and pointing toward the sky. I’m sure you were not satisfied with this shot. We need to correct two flaws at the top to help you hit the ball with a square clubface. 1. The Flying Elbow 2. The out of alignment club shaft.
You can study different parts of your swing while the gif repeats the swing over and over. Focus on different areas for several times in a row to better visualize your swing parts. It’s easy to see the Flying Elbow, the slightly cupped wrist due to the Flying Elbow, and you can see that the clubface is perfectly square at impact. What you may not notice at first is the significant reaching across your chest with the left arm and the amount of rotation in your lower arm, but it’s there. You can correct this with a better shoulder to start the swing. As I’ve mentioned, it ideal to get at least three-fourths of your shoulder pivot by the time your club shaft reaches waist high, parallel to the ground.
With your driver, but pretty much the same flaws as with your irons. But the open clubface is more visible because the driver head is so much larger than your iron club.
Mostly the same except the clubface appears to be square at impact.
This is a good front view of your driver swing. Just half of it for the purpose of looking closely at impact. Your clubface is square here. Too much knee dipping for me, but if you need it don’t worry about too much for now. We need to work mostly on your upper body motion.
