     Kelvin Miyahira is a moron who knows squat about free body force system as an engineer would know. He is asking us to “look at” and “see” something that is not being quantified by anything other than arbitrary observation.
     The question is not “does the swing start from the ground up”, it is “what is happening between the ground and the soles of the shoes as the golfer starts his swing sequence”?
     This question is answered by force plate measurements under the shoes and it confirms that whatever motions are initiated by the golfer the resulting forces and torques are resolved between the ground and shoes. Then those patterns are related to determine what is actually happening.
     Kelvin is not a graduate engineer so he depends on his personal visual observations and applying intuitive physics to the golf swing. He is a shyster, plain and simple, but gullible golfers want to believe him just as they want to believe Homer Kelley’s TGM. It’s so pathetic.

       @sk, I too have disagreed with Kelvin M, but go easy on the guy
       About year ago he suffered a massive stroke at a very young age.

       Save your “moron, shyster” comments for Potus.
       Kelvin unlike Potus hasnt had malice in his motivation.

   Been trying SC methods for a couple of months and today shot my best score for 10 years.
   Thank you Shawn, brilliant!
   I will be 60 on Monday

     So share your best score with us. Did you break 100?

       What’s your point?

   Sorry, Shawn, but you don’t use ‘forces’ and ‘energy’ coming up from the ground because the ground is just the foundation that supports and reacts to the forces and torques you generate from your body.
   The correct engineering terminology is “Ground Reaction Forces” (GRFs) that react to the forces from your body. The ground simply resists your body generated forces. Understand?
   What you are advocating for the golf swing is good, but your interpretation of Newton’s Laws of Motion is somewhat off.
   As an engineer I shudder how so-called ‘top’ golf instructors use Newtonian Physics terminology because they get it mostly wrong, but it doesn’t matter because the average golfer is ignorant and the scientific errors are irrelevant to the task at hand.

     This is my ‘engineering’ explanation of GRFs. IOW the ground is dead and only reacts to the forces coming from the golfers shoes.
     Most golfers and teachers think of the swing as starting from the club head and back up into the arms and core and stops there. The hips, legs and feet are just there to hold up things and should be kept ‘quiet’.
     Others believe the swing starts from the ground up but that’s too far away from the club head and ball to understand.
     The reality is the kinetic sequence chain utilizes the ground up and not from the club head.
     For simplistic golfers club hits ball, ball goes far, ball goes far, best club hits best ball. I want them.
