What causes muscles to stop responding to stimuli?
Hey Rip,
I am relatively new to your program but am definitely enjoying the gains being made. I have only read SS 3rd edition so excuse me if this is explained in other books you have written, but I am curious as to what causes your muscles to stop adapting to the additional stress being put on them with linear progression.
I understand that as weights reach higher quantity, the amount of muscle mass/synapse response, CNS response, etc requires more growth than it does at lesser weights, but I do not understand why the increments cannot just be lessoned... What causes your muscles to stop responding to the increase when they reach a certain level?
