Prilepin's Chart Explained — and Its Limits

2026-08-21

Prilepin's chart tells you how many reps belong at a given percentage. It is a useful yardstick, but it came out of weightlifting — and that explains both what it is good for and where it stops applying.

Prilepin's chart is one of the most quoted tables in strength training. It answers a question programs rarely address directly: how much work belongs at this load?

It is also a chart used far more widely than it was ever built for. This article covers what it says, where it came from, and where you step outside it.

The chart

The numbers apply to one lift in one session — not to the whole workout and not to the week. Warm-up sets do not count; only working sets in that percentage band.

An example. If your max is 140 kg and you are squatting 115, you are at 82 % — the third row. The chart says 2–4 reps per set, about 15 in total, with 10–20 acceptable. In practice, five sets of three. The Prilepin calculator works this out directly.

Two instructions, not one

The second column gets overlooked, though it matters as much as the total. The chart constrains both set length and total reps.

The difference shows immediately in an example. Eight reps at 90 % could in principle be one set of eight — but by the chart it is four sets of two. The total would be identical, yet the first version is practically impossible and would serve no purpose.

The reason for that is the chart's whole underlying idea, and it is worth pausing on.

The chart is about quality, not fatigue

Prilepin's chart is often read as a volume recommendation — as if it said how much work is needed to progress. That is not its subject.

The chart describes how much work can be done before the quality of the reps falls off. The observation behind it is bar speed: once enough sets accumulate, the bar slows and technique degrades. The chart's numbers are where that typically happens.

Which gives you the right way to read it. It is not a target to be met every session. It is a ceiling, past which extra work produces worse reps than the ones before. The optimal figure is the middle of a range, not a quota.

Where the chart came from

A. S. Prilepin was a Soviet weightlifting coach, and the chart dates from the 1970s. The commonly told account is that it was assembled by analysing the training logs of a large group of lifters — usually given as around a thousand elite weightlifters — and looking for recurring patterns in what the most successful ones did.

Worth being honest here: the original data is not available in the West. The chart reached us through second-hand sources, and its exact methods, sample and analysis cannot be checked. That does not make it wrong — coaching experience supports it broadly — but it does mean it should not be treated as a measured result.

The more important consequence of its origin is a different one: the subjects were weightlifters, and the lifts were the snatch and the clean and jerk.

Why the sport matters

The weightlifting movements are explosive and technical. The bar has to be accelerated hard, and if speed drops the lift fails — not because strength ran out, but because the bar does not travel high enough. In weightlifting a slow rep is effectively a failed rep.

In the powerlifts the situation is different. A slow squat or deadlift is a perfectly valid rep, and often the heaviest, slowest one is the most valuable of the session. A powerlifter can benefit from work that Prilepin would have counted as degraded quality.

This is the chart's most important limitation. It is used heavily in powerlifting and works reasonably well there — but that is an adaptation, not what the original data said.

Four other things the chart ignores

The week. The chart speaks about one session. It says nothing about how often the lift should be trained — and weightlifting frequency was typically far higher than in ordinary strength training. Hitting these numbers three times a week is not the same proposition as once.

Deadlifts. Many coaches consider the figures too high for the deadlift specifically. The lift taxes recovery more than its rep count suggests, and in practice deadlift work often sits near the bottom of the range.

Accessory work. The chart covers main lifts. A barbell row or a curl falls entirely outside it, and percentage-based loading is not especially meaningful there anyway.

The individual. The chart is an average of elite lifters. A beginner is not an elite lifter, and an elite lifter's optimal workload is not automatically right for anyone else. The same holds for recovery: an identical amount of work is a different thing at 20 and at 45.

How to actually use it

The best use is not to build a program on the chart but to use it as a check.

1. Plan the session normally. Pick the lift, load and sets according to whatever program you follow.
2. Count the reps and the percentage. How many working reps, and at what percentage.
3. Compare with the chart. Inside the range, the session is probably sensible. Well over it, ask why.

Going over is not automatically a mistake. It is a question that should have an answer — a deliberate overload week, say, or a lift you know you tolerate more of. Without an answer, exceeding the range is usually just unplanned work.

The check works in the other direction too. If a session falls well below the bottom of the range several weeks running, there is probably not enough load or volume there to drive progress.

Summary

Prilepin's chart says how many quality reps a percentage band typically allows before performance starts to fall off. It constrains set length as well as total volume, and the optimal figure is a midpoint rather than a target.

It comes from weightlifting, and that is where it is sharpest. In powerlifting and general gym training it is a good rule of thumb and a poor law — and in the deadlift especially, the lower end of the range is the safer place to sit.
