1 Rep Max Percentage Chart (Complete Guide)

Last updated: May 2026

A 1 rep max percentage chart converts your one-rep max into exact training loads for any set and rep scheme. Your 1RM is 100%. Every other weight you lift is a percentage of that number. Find your rep range, multiply your 1RM by the percentage, and you have your training load — no guessing.

Below you’ll find the standard percentage chart, training zone guidelines, Prilepin’s chart (the NSCA’s evidence-based volume framework), and strength standards for bench press and squat.

1 Rep Max Percentage Chart

This table shows the percentage of your 1RM you’re working at for any given rep count, along with the primary training adaptation for each zone.

Reps	% of 1RM	Training Focus
1	100%	Maximal strength test
2	97%	Maximal strength
3	94%	Maximal strength
4	92%	Strength
5	89%	Strength
6	86%	Strength
7	83%	Strength–hypertrophy
8	81%	Strength–hypertrophy
9	78%	Hypertrophy
10	75%	Hypertrophy
11	73%	Hypertrophy
12	71%	Hypertrophy
13	70%	Hypertrophy
14	68%	Hypertrophy–endurance
15	67%	Muscular endurance
16	65%	Muscular endurance
17	64%	Muscular endurance
18	63%	Muscular endurance
19	61%	Muscular endurance
20	60%	Muscular endurance

Example: Your squat 1RM is 300 lb. Your program calls for 4 sets of 5. Look up 5 reps → 89% → 0.89 × 300 = 267 lb. Round to 265 lb.

To use this chart you need to know your 1RM. If you haven’t tested it, you can estimate it from any working set using the calculator below:

Training Zones by Percentage

The percentage chart becomes a programming tool once you understand what each zone produces:

% of 1RM	Rep Range	Primary Goal	Common Use
90–100%	1–3	Maximal strength	Powerlifting-style peaking
80–90%	3–6	Strength	5/3/1, linear progression top sets
70–80%	6–9	Strength + hypertrophy	Most intermediate programs
60–70%	10–15	Hypertrophy	Classic bodybuilding ranges
50–60%	15+	Muscular endurance	High-rep sets, conditioning work

Most intermediate lifters training for both strength and muscle spend the majority of their time in the 70–85% range — roughly 5–12 reps. This zone provides enough mechanical tension to drive strength adaptations while accumulating sufficient volume for hypertrophy.

There is no single best zone. Effective programs cycle through different intensities across a training block — a principle called periodization. Heavy weeks at 85–90% followed by moderate weeks at 70–75% is a common and well-supported approach.

Prilepin’s Chart (The NSCA Volume Guide)

Soviet sports scientist A.S. Prilepin analyzed the training logs of elite weightlifters in the 1970s and identified optimal volume ranges at each intensity. His chart has been adopted by the NSCA and is used by strength coaches to prescribe not just load, but total reps per session.

The percentage chart tells you what weight to use. Prilepin’s chart tells you how many total reps to do at that weight.

% of 1RM	Reps per Set	Optimal Total Reps	Total Rep Range
55–65%	3–6	24	18–30
70–75%	3–6	18	12–24
80–85%	2–4	15	10–20
90%+	1–2	7	4–10

How to read it: If you’re training at 80% of your 1RM, keep reps per set between 2–4, and aim for roughly 15 total reps across the session. You could get there with 5 sets of 3 or 4 sets of 4. Consistently exceeding the upper end of the range leads to more fatigue than adaptation.

Prilepin’s chart was built on Olympic lifting data and is most directly applicable to compound barbell movements — squat, bench press, deadlift, and overhead press. It’s less relevant for isolation work or machine exercises.

Bench Press 1RM: Strength Standards by Training Level

These benchmarks reflect 1RM data from tens of thousands of real lifters. They give you a data-backed reference point for where your bench press stands.

Training Level	Men (lb)	Women (lb)	What It Means
Beginner	103	55	Stronger than 5% of lifters
Novice	154	82	Stronger than 20%
Intermediate	217	104	Stronger than 50%
Advanced	291	132	Stronger than 80%
Elite	372	198+	Stronger than 95%

These figures apply to a lifter weighing roughly 165–185 lb (75–85 kg) for men. Heavier lifters will generally have higher absolute numbers. For more detailed benchmarks broken down by bodyweight and age, see the related article below.

Squat 1RM: Strength Standards by Training Level

Training Level	Men (lb)	Women (lb)	What It Means
Beginner	141	75	Stronger than 5% of lifters
Novice	203	121	Stronger than 20%
Intermediate	277	176	Stronger than 50%
Advanced	369	241	Stronger than 80%
Elite	473	318+	Stronger than 95%

A common benchmark: at intermediate level, most lifters squat roughly 20–30% more than they bench press. If your squat and bench 1RMs are within 5–10% of each other, either your squat technique has room to grow or your upper body pressing is ahead of the curve.

How to Find Your 1RM

You have two options:

• Estimated 1RM (recommended for most): Perform a set with a weight you can handle for 3–10 reps, then calculate your 1RM using a formula like Epley or Brzycki. This is safe, practical, and accurate to within 5% for most lifters.
• Tested 1RM: Work up to a true single with maximum weight. Suitable for experienced lifters with solid technique and a spotter. Requires a structured warm-up protocol.

For most intermediate lifters, an estimated 1RM from working sets is accurate enough for percentage-based programming. You don’t need to max out every training block.

Frequently Asked Questions

What does % of 1RM mean?

It means the percentage of your one-rep maximum for a given lift. If your bench press 1RM is 200 lb, then 80% of 1RM is 160 lb. Programs written in percentages use your 1RM as a reference point to prescribe loads that match specific training goals.

How accurate is the 1RM percentage chart?

It is a population average, not an individual guarantee. Some lifters — particularly those with a higher proportion of slow-twitch muscle fibers — can complete more reps at a given percentage than the chart predicts. Use it as a starting point and adjust based on what you observe in practice.

Should I use my actual 1RM or a training max?

For most intermediate lifters, a training max (90% of your actual 1RM) is the smarter base. All percentages are calculated from the training max, not your all-out max. The result is that early weeks of a program feel achievable rather than maximal, which supports consistent progress and reduces the risk of grinding through weights you’re not ready for. Jim Wendler’s 5/3/1 program popularized this approach.

What is the NSCA 1RM chart?

The NSCA (National Strength and Conditioning Association) references Prilepin’s chart in its Essentials of Strength Training and Conditioning textbook. It is the same loading framework shown above. The NSCA uses it to guide volume and intensity prescription in evidence-based strength programs.

How often should I retest my 1RM?

Every 8–16 weeks, typically at the end of a training block. Testing more frequently adds unnecessary fatigue. Between formal tests, most lifters track progress using estimated 1RM calculated from working sets.
