Yeah, that’s probly what happened. You don’t have to take a day off after–I prefer less days off in the week than more because I hate doing nothing–but don’t do heavy shit of any kind the next day. Rep work or light bodybuilding style work is a go though. Just don’t put all kinds of drop-sets and crap in there, because that can wear on you too. Just basic rep work leaving a couple in the tank.
Or hell, you could do conditioning/sled work the next day.
Long term I’ve noticed that the CNS/joo joo thing is a function of overall work capacity. There is a way to train yourself to handle and respond to more frequent heavy pulling or just heavy work in general–if there wasn’t there would be no way we have guys snatching or squatting heavy 6x a week for Oly lifting or whatnot-- but you have to do it slow. Frequency can absolutely work…but only provided you’re prepared physically for it.
That being said, if you’re pulling 700 lbs or something, you’re still going to be wiped most of the time. The closer you are to “elite” the more drain everything has on your CNS (that’s the 5 second version of the story).
