Muscles may not have intelligence, but they do display the attributes of "Memory". Sayings like, "it's just like riding a bicycle", come to mind.
Certainly it's true that the brain remembers the engineering principles of a "Bike Ride", but it is the muscles that perform them and do so just as if it was yesterday.
When we "TRAIN" anything, we do so in a manner that "Repeats the same Message". If you want the dog to Roll Over, then you do Not change the command each time you ask him. And so we can see that "Consistency" allows the Subject to "Learn" what is being asked of it.
Adapting and Responding:
After eight weeks of consistent training, a muscle will have pretty well gone in the direction you were visualizing...or not.
Depending on you, your DNA, Diet, Quality of Rest, this may need 12 weeks to make an assessment or as little as 6. But this length of time committed to a Specific Training regimen, is Fair and anything less isn't.
Most of the "Muscle Confusion" I have seen, is the culmination of Poor technique coupled with, bad advice and a pinch of Vanity.
99% of your training Results are a by-product of your Focus and committed determination. Do not sacrifice these things to the Gods of Over Exertion, always live to fight another day, let your training time be "Your Time, not the other guy's. There are No Secrets, just wisdom.
