Enter the percentage of your 1RM you're planning to train at and get the recommended rep range per set, total session reps, and optimal total reps from the classic Prilepin's Table.
Prilepin's Chart is a reference table matching a percentage of your one-rep max to a recommended number of reps per set and total reps for the session. For example, training at 75% of your 1RM calls for sets of 3-6 reps, with 12-24 total reps across the session and an optimal total of around 18 reps. It's a starting guideline for balancing intensity and volume, not a rigid rule.

A.S. Prilepin was a Soviet sports scientist who, in the 1970s, analysed the training logs of more than 1,000 elite weightlifters to find patterns in how the best lifters combined intensity (percentage of 1RM) with volume (total reps) in a single training session. The result — now known simply as Prilepin's Table or Prilepin's Chart — is a compact set of guidelines that pair each intensity band with a recommended rep range per set, a total rep range for the session, and an "optimal" total that tended to correlate best with strength gains in the lifters he studied.
The chart is used to sanity-check a training session before it's written: pick the percentage you're planning to lift at, and the chart tells you roughly how many reps per set and how many total reps tend to work best at that intensity. It was compiled from Olympic weightlifting data (snatch and clean & jerk), but its logic — match volume to intensity so you get enough stimulus without excess fatigue — has been widely adopted well beyond weightlifting, and coaches in powerlifting and general strength training reference it constantly when programming squat, bench press and deadlift work, even though it wasn't originally built from powerlifting numbers.
Enter the percentage of your 1RM you intend to train at. The calculator matches that number against the four intensity bands of Prilepin's Table and returns the corresponding rep range per set, total rep range for the session, and optimal total rep count. If you also enter your 1RM, it multiplies that figure by your percentage to show the actual working weight you'd load on the bar.
The reasoning behind the table is straightforward once you think about what happens at each end of the rep spectrum. Too few reps at a given intensity under-stimulates the muscle and nervous system — there simply isn't enough total work being done to drive an adaptation. Too many reps, especially at higher percentages, pushes a lifter into excess fatigue: technique starts to break down under a heavy bar well before genuine strength-limited failure, and the extra reps add junk volume without adding useful training stimulus. Prilepin's data suggested a "sweet spot" total-rep range for each intensity band that tends to maximise strength stimulus while keeping fatigue and technical breakdown in check — that sweet spot is what the "optimal total reps" column represents.
The table below is the classic four-row version of Prilepin's Chart, as it's cited across weightlifting and strength coaching literature. The same figures are shown in the calculator above the moment you enter a percentage.
| % of 1RM | Rep Range per Set | Total Reps (Range) | Optimal Total Reps |
|---|---|---|---|
| Below 70% | 3-6 | 18-30 | 24 |
| 70-79% | 3-6 | 12-24 | 18 |
| 80-89% | 2-4 | 10-20 | 15 |
| 90% and above | 1-2 | 4-10 | 7 |
Prilepin's Table was derived from Olympic weightlifting logs — primarily the snatch and clean & jerk, which are fast, technical lifts performed for low reps even at moderate intensities. Slower, more grinding powerlifting-style lifts (squat, bench press, deadlift) don't always behave identically, and many coaches adapt the guidelines slightly — for example leaning toward the lower end of a rep range on deadlift, where technical breakdown under fatigue carries more risk. The table also doesn't account for individual differences in recovery capacity, training age, exercise selection, or how a lifter happens to be feeling on a given day.
Treat Prilepin's Chart as a general, well-tested guideline for structuring volume around a given intensity — a sensible default to check a session against — rather than a rigid formula that must be hit exactly in every workout. A qualified strength coach can help adapt it to your specific lifts, goals and recovery capacity.
What is Prilepin's chart used for?
Prilepin's chart is used to guide how many reps per set and total reps to perform at a given percentage of your one-rep max. It helps lifters and coaches program a sensible volume of work for a chosen training intensity — enough to stimulate strength gains without accumulating excess fatigue or letting technique break down.
Who was Prilepin and where does the chart come from?
A.S. Prilepin was a Soviet sports scientist who analysed the training logs of more than 1,000 elite weightlifters in the 1970s. By studying how the strongest lifters combined intensity and volume, he identified the rep ranges and total-rep guidelines that make up the table that now carries his name.
Does Prilepin's chart apply to powerlifting or just Olympic weightlifting?
The chart was originally compiled from Olympic weightlifting data — the snatch and clean & jerk. Despite that origin, it's widely used across powerlifting and general strength training as well, since the underlying principle (matching volume to intensity) applies broadly. Some coaches adapt the exact rep ranges slightly for slower, more grinding lifts like the squat, bench press and deadlift.
What happens if I do fewer or more reps than Prilepin's chart suggests?
Doing noticeably fewer reps than the suggested range risks under-stimulating strength adaptation — there may not be enough total volume to drive meaningful progress. Doing significantly more reps, especially at higher intensities, tends to add fatigue and can cause technique to break down before genuine strength-limited failure. The chart's ranges exist to avoid both extremes, but small deviations session to session are normal.
Can I use Prilepin's chart for every exercise?
It works best for main compound barbell lifts — squat, bench press, deadlift, and Olympic lifts — where 1RM and percentage-based programming are standard practice. It's less useful for isolation exercises, machine work, or movements where a true 1RM isn't typically tested or trained.
What if my percentage falls right on the boundary between two bands, like exactly 70% or 80%?
The classic table treats 70-79% and 80-89% as their own bands, so 70% sits at the bottom of the "70-79%" band and 80% at the bottom of the "80-89%" band. At boundary percentages the two adjacent bands' recommendations are usually close enough that either interpretation works fine in practice — use your judgement and how the set feels.
Is Prilepin's chart still relevant today, decades after it was compiled?
Yes — it remains one of the most widely cited volume-intensity guidelines in strength sports, and modern coaches still reference it when building programs. Sports science has added nuance since the 1970s (such as accounting for individual recovery and training age), but the core relationship it describes — pairing appropriate volume with a given intensity — has held up well and is still taught in strength coaching education today.
