In the gym, PR means personal record.

It’s basically your best-ever performance in a specific exercise or fitness test.

That could be:

  • Heaviest weight you’ve ever lifted for an exercise (like your strongest squat or bench).
  • Most reps you’ve done at a certain weight (e.g., 60 kg bench for 10 reps instead of 8).
  • Fastest time or longest distance for a run, row, bike, etc.

So when someone says, “I hit a PR on deadlift,” they mean they just beat their previous best on that lift.

Mini example:
Last month you benched 60 kg for 5 reps. Today you get 60 kg for 6 reps. That new set is your PR for 60 kg bench reps.

People track PRs to measure progress, stay motivated, and set new goals over time.

TL;DR:
“PR” in the gym = your personal record, your best performance so far on a given exercise or activity.
