I have a difficult time picturing how a person with two hands couldn't pull and push simultaneously.
Why couldn't they?
Works well for turning shopping carts.
Can the same hand push and pull? I don't see how.
Can one hand push and and hand pull? I don't see why not.
Is it a good thing? Wish I knew.
Seems like, in theory, it would be worth investigating.
In the World of TGM, Zone 2 is the application of mechanical advantage to increase Pivot Speed. The Straightening of the "Triangle" by Left Arm or Right Arm is mechanical advantage. The #2 Accumulator is also mechanical advantage whether it's passive or active, using CF or Power Package Thrust respectively. So, moving from bent to straight IS(part of) the mechanical advantage. It doesn't matter if you push or pull. That's only the "How". But the Pivot supplies all of the Power.
TGM is very much about the Pivot Supplying all of the Power (in Pivot Strokes). Somewhere it says that the arms should not substitute for the pivot.
Don't let me mislead you. The Arms are Power, but only in the sense that the Power comes from a "Pulley" or "Inclined Plane" or "Screw" or "Lever".
The Pivot is direct energy, stored by the Accumulators as Potential energy and released into Clubhead Kinetic Energy.
Anyway, I think I got most of that right. Pushing and Pulling is the "How" of Mechanical Advantage. Push and Pull is "How" the Accumulators are released. If three Accumulators aren't adding enough advantage, use four. That means you can store potential Power in 4 places, then increase or decrease their release overlap to refine.
Homer Kelley isn't saying that that's the way everybody gets the job done but he is saying that that's the way everybody "should" get the job done.
Quote:
No amount of effort will produce more than a player’s maximum turning speed. Regardless of effort you simply cannot push anything faster than you can run. Mechanical Advantage (1-H) must be utilized making Clubhead acceleration on “Overtaking” process (2-P, 6-M-1).
Mechanical Advantage is the factor by which a mechanism multiplies the force applied to it.
This is just a personal note from me. It's unfortunate that TGM seems so focused on pulling and pushing. Homer gave everything equal emphasis but because component variations need to be chosen in light of Hitting or Swinging, it seems to have gotten a lot of "Press" time.
Pushing and pulling is rudimentary. Absorb Zone 1,2 and 3 and keep their identities separate. The magic, mystery, answers, are not found in Hitting vs Swinging.
