So if you are not "chain linking" muscles together, then that means all of the power must be coming only from the muscles of the core
I'm not sure if you're paraphrasing me or Hunter, but I can't find where either of us is saying this.
I did say that local muscle has a tendency to interfere with the "chain linking". IMO this means you should try to recruit everything - including local muscle - in the "chain linking", instead of allowing it to interfere. This needs to be practised and I still have a long way to go.
