In lifting, PR stands for Personal Record, which is the heaviest weight you have ever lifted. It is a term used to measure how much weight you can lift in a given exercise. Hitting a PR in the gym means that you have become stronger, or at least that you have never attempted that weight and rep number before. PRs are significant because they help to keep your training moving in the right direction. There are different types of PRs in lifting, including:

• 1RM: This is the maximum amount of weight that can be lifted a single time for a given exercise.

• Repetition: This is the number of repetitions that can be completed at any given weight, for any given exercise.

• Volume: This is the total amount of weight lifted in a given workout, calculated by multiplying the number of sets, reps, and weight lifted.

To increase your PR, you need to practice the specific exercise which you wish to improve and train with increasingly heavier weights. However, it is important to note that the advanced lifter might need 6–12 weeks of training before a new PR attempt is meaningful, and the beginner lifter doesn’t have any business going for one-rep PRs at all.
