Percentages are a planning guide, not a guarantee. How many reps you actually get at a given percentage varies by lift, training, and the day — treat the chart as a starting point and adjust to what the bar feels like.
How training percentages work
A percentage chart is your one-rep max, sliced into training loads. Your 1RM is the most you can lift once. Every lighter weight you train with is some percentage of it — and because strength programs are written in those percentages (“work up to 3×3 at 90%”, “5×5 at 80%”), a chart that converts each percentage into an actual number is what turns a program into a plan you can load on the bar.
The percentage you choose isn't arbitrary — it decides both how many reps you can do and what your body adapts to. Heavy percentages let you do only a few reps but build maximal strength; moderate percentages let you do more reps and drive muscle growth; light percentages are for speed, technique, and endurance work. So the chart shows three things for every row: the load, the reps that percentage is good for, and the training zone it belongs to.
The rep estimates come from a large 2024 meta-analysis of repetitions-to-failure research — about 3 reps at 95%, 7 at 85%, 10 at 80%, 12 at 75%, 15 at 70%. They run a little higher than the older charts you may have seen, which were built on a much smaller base and tend to understate the reps below about 80%. The number still shifts by exercise and by lifter, so treat the rep column as a strong guide, not a promise — and remember it's reps to failure, not the reps you'd be programmed to do per set.
The percentage chart
Here's the full reference: each percentage of your one-rep max, the approximate reps a trained lifter gets there on a big barbell lift, and the training zone it sits in. Enter your max in the calculator above to put real weights next to every row.
| % of 1RM | ≈ Reps | Training zone | Typical set |
|---|---|---|---|
| 100% | 1 | Maximal strength | 1–3 reps a set · 4–10 total |
| 95% | ~3 | Maximal strength | 1–3 reps a set · 4–10 total |
| 90% | ~5 | Maximal strength | 1–3 reps a set · 4–10 total |
| 85% | ~7 | Strength | 3–5 reps a set · 10–20 total |
| 80% | ~10 | Strength | 3–5 reps a set · 10–20 total |
| 75% | ~12 | Hypertrophy | 6–10 reps a set · 15–30 total |
| 70% | ~15 | Hypertrophy | 6–10 reps a set · 15–30 total |
| 65% | ~17 | Muscular endurance | 12–20 reps a set |
| 60% | ~20 | Muscular endurance | 12–20 reps a set |
| 55% | ~22 | Muscular endurance | 12–20 reps a set |
| 50% | ~26 | Muscular endurance | 12–20 reps a set |
| 45% | ~30 | Speed & technique | 3–6 fast reps, not to failure |
| 40% | ~36 | Speed & technique | 3–6 fast reps, not to failure |
| 35% | ~42 | Speed & technique | 3–6 fast reps, not to failure |
| 30% | ~51 | Speed & technique | 3–6 fast reps, not to failure |
The “typical set” column is programming guidance in the spirit of Prilepin's table — the reps-per-set and total-rep ranges strength coaches use to keep volume productive at each intensity. They're starting points, not rules.
The training zones
Maximal strength (about 90%+). Singles, doubles, and triples with very heavy loads. This is where you build peak force and the skill of grinding a near-limit weight — the business end of a powerlifting peak. Keep total reps low; quality over quantity.
Strength (about 80–89%). The classic strength-training range: heavy enough to drive real force production, light enough to accumulate meaningful volume across sets of 3–5. Most of a strength program lives here.
Hypertrophy (about 70–79%). Moderate loads for sets of roughly 6–10, the bread and butter of building muscle. You can do enough reps to drive growth without the load being so light that fatigue outpaces the stimulus.
Muscular endurance (about 50–69%). Lighter weights for higher-rep work capacity, plus back-off and pump sets. Builds the engine, not the ceiling.
Speed & technique (below about 50%). Light and fast — explosive speed work and grooving technique, moved crisply rather than ground out. Useful, but not where you build a bigger max.
Common mistakes with percentages
- Working off an outdated max. The whole chart scales from your 1RM. If your max is months old and you've gotten stronger, every percentage is too light. Re-check your max every few weeks.
- Treating the rep numbers as a target. They're the ceiling — the most you could grind to failure. Most training should leave a rep or two in reserve, so work a bit below the chart's reps.
- Assuming every lift behaves the same. The rep estimates fit the big barbell lifts best. You'll usually get more reps at a given percentage on machines and isolation work, and sometimes fewer on the deadlift near maximal loads.
- Ignoring how you feel on the day. A percentage is a fixed plan; your body isn't. If 80% feels like a grind today, it's fine to back off — that's what autoregulation with RPE is for.
- Chasing precision the method doesn't have. The difference between 82.5% and 85% is smaller than your day-to-day variation. Round to a loadable weight and train; don't agonize over a half-percent.
Methodology
Loads are simply your one-rep max multiplied by each percentage. The 100% row shows your entered max exactly; every lighter row is rounded to the nearest loadable increment (5 lb or 2.5 kg) and never rounds above your max. The reps-to-failure figures use the main model from a 2024 Sports Medicine meta-regression (Nuzzo and colleagues) that pooled hundreds of repetitions-to-failure studies against measured maxes — the most defensible general estimate currently available. It runs higher in the mid-range than the older formula-based charts, which were built on a much smaller evidence base.
Those rep counts are reps to failure, and they are kept deliberately separate from the per-set programming guidance — a set of 3 at 85% and a set taken to failure at 85% are very different training stimuli, and treating them as the same is the classic percentage-chart mistake. The programming column follows the logic of Prilepin's table for the heavier strength bands and the NSCA/ACSM repetition continuum for goal labels: maximal strength, strength, hypertrophy, and endurance/speed. Per the research these boundaries overlap — hypertrophy in particular happens across a broad loading range when sets are hard enough — so they're a guide, not fixed cut-offs.
The estimates are most accurate for trained lifters on the big compound barbell lifts. They shift by exercise, training status, and day-to-day readiness — so this is a planning tool, not a guarantee. Always warm up properly and adjust to what the bar actually feels like.

What is a weightlifting percentage chart?
A percentage chart shows training loads as a percentage of your one-rep max (1RM). Most programs are written in percentages — 5×5 at 80%, a heavy single at 95% — and the chart turns those into the actual weight on the bar, plus roughly how many reps each percentage is good for and what training goal it serves.
How do I use it?
Enter your one-rep max and the chart fills in every load from 100% down to 30%. For a program instruction like “3×5 at 85%”, read across the 85% row. Switch to the big-lifts view to chart squat, bench, deadlift, and overhead press side by side and program a whole session at once.
How many reps can I do at a given percentage?
Roughly: 100% is one rep by definition, 95% about 3, 90% about 5, 85% about 7, 80% about 10, 75% about 12, 70% about 15. These come from a large 2024 meta-analysis and run a little higher than the older charts, which understated the reps below about 80%. They're typical to-failure numbers for trained lifters on big barbell lifts — the real count shifts by exercise, training background, and the day. And they're reps to failure, not the reps you'd program per set.
What do the training zones mean?
The percentage you train at determines the adaptation. 90% and up builds maximal strength in low reps. 80–89% is the classic strength range. ~70–79% is the sweet spot for muscle growth. Lighter loads build endurance; very light, fast work is for speed and technique. The boundaries overlap rather than being hard lines — but they map what each intensity is best at.
What if I don't know my one-rep max?
You don't need a true max test. Take a recent heavy set — a weight you got for 3–5 hard reps — estimate your 1RM from it, and enter that. Estimating is safer than a max attempt and accurate enough for programming. Re-check it every few weeks as you get stronger; the whole chart scales with your max.
Should I actually do the max reps the chart shows?
Usually not. The rep numbers are the ceiling — the most you could grind out at that percentage taken to failure. For most training, leave a rep or two in reserve, so working sets sit a little below the chart's count. Failure on every set adds fatigue without much extra benefit. Use the numbers to understand an intensity, then program just short of it.
Percentages or RPE — which should I use?
Both, ideally. Percentages give a fixed plan from your max — great for structure. RPE adjusts to how you feel on the day, which percentages can't. Many lifters set the load from a chart, then autoregulate with RPE if the day feels light or heavy. You can carry your max straight into the RPE calculator from here.
Is the chart the same for every lift?
The loads scale to each lift's own max, but the reps-per-percentage estimates fit the big compound barbell lifts best — squat, bench, deadlift, overhead press. Machines and isolation lifts usually allow more reps at a given percentage; the deadlift often allows fewer near maximal loads. A solid guide for the main lifts, rougher elsewhere.
Train in percentages without the spreadsheet
The chart gives you the numbers. Stronger plans your loads from your max, logs every set, and updates the whole chart as you get stronger.
