All-nighter and hit a PR at the gym
The evidence
Strength drops 5-11%, your sense of body position dulls, and injury rates rise — the day you go for a personal record becomes the day you get hurt. The flip side works: banking extra sleep the week before is real (Rupp 2009).
The mechanism, in brief
The popular beliefs about all-nighters fall into two groups by where they go wrong: illusions about subjective versus objective, and illusions about short term versus long term.
