Hey, your can't understand my beach ball better than me. I made that one up myself LOL.
Once again, I look at the beach ball different than you do so I must be on a different beach than you.
Like most times on this forum:Anything someone says is wrong until proven with science yet, the things you propose (lateral Movement) has no scientific validation. Once again - perceptions, as long as they are yours, are correct.
Lets agree to disagree, since our analysis is coming from two entirely different perspectives.
The spine is shaped like an "S" and it depends what part of the spine you are looking at to determine if it is closer to the back than the front. I have yet to cut myself open to find out but I bet it is easier to to the spine from the back than it is the front - especially the part I am talking about.
When you look at the back, where the spine is - you see a totally different perspective of what is going on.
The SPINE does return to the same position if you look at the back view. If you cant see it, you are ignoring it or teaching otherwise only shows, as my youtube video shows, that lateral motion is not the answer.
For those who read these posts for help and instruction, I am begging you NOT to try to laterally SLIDE in your golf swing. I have seen way too many Natural Golfers eliminate rotation of the hips and slide causing numerous problems.
