In the slingshot example, to me it's the slingshot itself that gets loaded and unloaded. The rock is merely an instrument that is placed in side. Much like the swing. It isn't the bat that is being loaded. The bat is merely the instrument being used. To me, loading is more about power generation than anything else. I'm not interested in loading the bat or my hands for that matter. If you stated that the core was loaded. Or that the obliques were loaded. Or that the rear hip/leg was loaded, that would make more sense to me.
But if your analogy works for you, who am I to argue. As a person that studies the greats and what they say, I'm sure you have noticed that many use different descriptions. We can take their words and try to understand them in ways that make sense to each of us, but they each have their own variations.
Nice. FP I was never a great descriptive writer or person for that matter so there’s that. But the way I see/feel the barrel being pulled through via core stretch makes it ‘feel’ like the barrel gets ‘slung’ forward. Just my feel. Thanks for the convo. As always.
