Sounds like you may be trying to get them to feel what you feel. You can’t tell people what they feel or should feel all the time. People’s proprioceptions, physical ability, muscle strength can be vastly different from one to the other.
You keep saying ‘appearance of improvement.’ I don’t even know what you mean by that. If a student is moving his head 6” front side and drifting his body with hit and getting his club stuck back forcing him to throw the club to catch up..that’s a poor movement. You get him to make a centered pivot and correct this problem it’s not just an appearance.
How you achieve that may not be the same for every student. I’m no professional by any means. @iacas is. It just seems like you’re trying to suggest feels are universal.
Another thought I had - fill something the size of a tennis ball tin with solvent and then sit the grip in the solvent bath to ensure the tape gets thoroughly soaked. Anyone tried this? Any downsides I haven't thought of?
Day 3: DONE.
What I like:
That the videos are short, simple and follow a very logical progression. It feels like somebody who's never played the game before could start this series and "build" a golf swing.
I like that they focus on fundamentals. Seems obvious, that trying to diagnose a swing fault from a crowd of folks on this forum is impossible. However, you see that a lot with online instruction. "If you have this fault do this..." …"What if I don't have this fault?"
I truly believe these lessons could dovetail with any swing coach's lessons you are getting... alright perhaps if you are learning a very "non-standard" golf swing... but there are other threads for that topic.
I like the way you have each lesson laid out in words above the video, so we can see what's covered. That makes a lot of sense.
What I might suggest going forward - I know you have a bunch planned, but since you are looking for suggestions....
Drills to promote balance
Drills to promote speed increases
I will always be working on posture. More posture drills are personally always welcome. Some may not need them, but finish position posture is something I tend to lose and rebuild often.
Set up differences between driver and irons (perhaps this is 2 sessions: Set up and Swing differences.)
Shot shape mini-course
Thoughts on Swing Thoughts
Thoughts on Enjoying Pressure
A video for all five or one video per each of the five swing keys - How to diagnose etc...
Putting fundamentals (I assume that's on the way.)
Read, Speed and Bead - How to diagnose which is failing you? How to work on them? If it can be done.
Perhaps a course strategy video? … Although that video you could just chuck down a copy of LSW and say "READ THIS".
Equipment fitting suggestions video?
Warm up routine video?
Golf related stretching?
These are all just suggestions. I am not a golf coach, but I've got a lot of experience working with golf coaches … I tend to need a lot of coaching. The videos you have done so far have been an absolute Godsent for me. I truly appreciate all of these videos you are doing. When this whole thing is over and we're all sure we're still employed I hope a bunch of folks reup to support this site and the incredible amount of content it provides.
