You probably have a target goal each day for what you do: 300 push-ups, 400 sit-ups, whatever. Then you probably go and set out to hit that number or damn near die trying.
The Bulgarian Method of powerlifting (or Squat Everyday) doesn't do this. You're supposed to stop as soon as you slow the bar down, or when you start to feel like shyt, or as soon as you're not confident you'll make the next set. There re no hard goals each day; you have an idea but it is what it is once you get under the bar.
There's no benefit to working past that pii t since you're just gonna have to do the same thing the next day and the next.
Most folks out here squatting once or maybe twice a week (three times for folks on StrongLifts or SS). But imagine if you had to go and squat everyday. There's a reason nikkas skip legs like a muhfukka but show up early for chest and arm days.
The whole point of TBM is frequency >>> *, so you have to play the long game if your gonna do that for 2-4 months (or longer) at a time. Burning yourself out in one session only sets you up for failure the next.
Also, remember that calis are a lot easier to recover from than weights. The reason you're more likely to snap your shyt up training your way with weights is your joints and connective tissues will give out way before the actual muscles will, especially when repeating the same movement patterns constantly (google overuse injuries).
