Personal Record

When people talk about PRs in the gym, the first thing that comes to mind is the max: the heaviest weight ever lifted for one rep on an exercise. But the concept is broader than that. Hitting 100 kg x 8 on the bench when your previous record was 100 kg x 6 is a PR. Even completing a set with a weight you had never used before is a PR. Any performance that beats your previous best counts.

Tracking PRs is essential for two reasons. The first is objective: numbers don't lie. If your PRs go up over time, your program works. If they've been stuck for months, something needs to change. The second is motivational: seeing in black and white that you lift more today than six months ago is the most powerful confirmation that the work pays off.

Different PRs exist for different contexts. The 1RM (one-rep max) is the classic, used in powerlifting as an absolute measure of strength. Volume PRs (e.g. weight x reps) are more useful in bodybuilding, where load isn't the only important parameter. You can also track 'estimated' PRs using conversion formulas that calculate a theoretical max from the number of reps performed at a given weight.

A practical tip: don't chase PRs every session. Testing a max is stressful for the body and the nervous system. PRs come as a natural consequence of a good program, not by forcing them every week. Log your training, and the records will come on their own.
