These top tier genetics specifically refer to being faster, stronger, more athletic, more explosive, etc, which would actually hurt a person's CNS recovery, because they're using more energy per movement. If CNS fatigue was as common as some of these guys claim, the top tier athletes wouldn't train 6-8 hours a day, they'd train even less than the average gym bro.I do not agree. these top level athletes have top genetics, and then don't work 40 hours per week. their life is their training, they get weekly massages, recovery protocols, they can eat amounts of food that make gym bro walk around 15 percent with muffin top and stay lean.
CNS overtraining is just an excuse to be lazy, for most people. Don't get me wrong, I'm not saying it's impossible, I'm saying it's nearly impossible and/or incredibly rare.
I've hit 35-40 sets per muscle group per week, and didn't feel any additional fatigue while blasting. I was also adding weight consistently.
