1RM Percentage Chart and Strength Standards for Beginners

A 1RM percentage chart tells you what share of your one-rep max (the heaviest weight you can lift once with good form) you can typically lift for a given number of reps. Using the NSCA training load chart: 1 rep is 100%, 5 reps is about 87%, 8 reps is about 80%, 10 reps is about 75%, and 12 reps is about 70%. Beginners should estimate their 1RM from a set of 5 to 10 reps rather than testing a true max, and use the chart to choose training weights.

Below is the full chart, how to estimate your max without risking injury, and how to use the numbers to keep making progress.

The 1RM percentage chart

This is the NSCA training load chart, with example weights for three one-rep maxes. All weights are in kg.

"Max reps" means reps done to the point where you couldn't do one more with good form. If you stopped with several reps left in the tank, the chart will underestimate your max.

Two things to keep in mind. First, this is an average. Some people can do more reps at a given percentage, some fewer, and it varies between exercises too. Second, you can't load 55.8 kg on most gym bars. Round to the nearest weight you can actually put on.

How do you estimate your 1RM safely?

Do a rep-max test instead of a true max. Pick a weight you think you can lift 5 to 10 times, do as many clean reps as you can, and stop the moment form starts to slip. Then use the chart above or a formula.

The two most common formulas:

• Epley: 1RM = weight × (1 + reps ÷ 30)
• Brzycki: 1RM = weight × 36 ÷ (37 − reps)

Worked example

Say you do 8 reps of bench press with 60 kg.

• Epley: 60 × (1 + 8 ÷ 30) = 60 × 1.267 = 76.0 kg
• Brzycki: 60 × 36 ÷ 29 = 74.5 kg
• NSCA chart: 8 reps ≈ 80%, so 60 ÷ 0.80 = 75 kg

All three land within a couple of kilos. At 10 reps with 50 kg, all three give the same answer: about 66.7 kg. The one rep max calculator does this maths for you and prints a full training-load table from your estimate.

Estimates get rougher as reps climb, so a set of 5 to 10 is the sweet spot. For heavier, more technical lifts, keep the test set at the low end. The US Department of Defense's Human Performance Resources site (HPRC), summarising NSCA guidance, notes that multiple-rep tests for lifts like the back squat aren't very reliable above 5RM because form breaks down with fatigue.

If you want to test a true 1RM

Only after a few months of consistent training, with a spotter or safety bars, on a lift you've practised a lot. The NSCA protocol, as summarised by HPRC, goes roughly like this:

1. Warm up with a light weight for 5 to 10 reps. Rest 1 minute.
2. Add 5 to 10% (upper body) or 10 to 20% (lower body) and do 3 to 5 reps. Rest 2 minutes.
3. Add the same again for 2 to 3 reps. Rest 2 to 4 minutes.
4. Add the same again and attempt 1 rep.
5. If it goes up cleanly, rest and add a little more. If not, rest and drop slightly.
6. Stop when you find the heaviest single you can do with proper technique.

A grinding, ugly rep where your hips shoot up or your back rounds doesn't count. That's how people get hurt.

How do you use percentages to plan training?

Once you have an estimated max, you can pick weights by goal. The American College of Sports Medicine's position stand on progression in resistance training gives these broad ranges:

For beginners the ACSM recommends 8 to 12 RM loads and training 2 to 3 days a week. If you're just starting, our beginner gym workout plan puts that into a four-week routine.

Example: planning bench sets from a 75 kg estimate

Say your estimated bench 1RM is 75 kg and you want to train in the 8 to 10 rep range.

• 75% of 75 kg = 56.25 kg, so load 55 kg for sets of about 10
• 80% of 75 kg = 60 kg for sets of about 8

You don't have to train to failure every set. Doing 3 sets of 8 with 55 kg, leaving a rep or two in reserve, is solid work.

What is progressive overload, and how do you do it?

Progressive overload just means asking a bit more of your muscles over time: more weight, more reps, or more sets. Without it, progress stalls.

The simplest version for beginners is double progression:

1. Pick a rep range, say 8 to 12.
2. Start with a weight you can lift for 8 good reps on every set.
3. Each session, try to add a rep to one or more sets.
4. When you hit 12 reps on all sets, increase the weight.
5. You'll drop back to about 8 reps. Build up again.

How much to increase? The ACSM position stand recommends a 2 to 10% increase in load when you can do one or two reps more than your target. For a 55 kg bench, that's about 1 to 5.5 kg. In practice, the smallest jump your gym allows is usually right. If the smallest plates are 1.25 kg, a pair adds 2.5 kg to a barbell.

A 6-week overload example

Here's a hypothetical squat progression, 3 sets per session, two sessions a week:

Progress won't be this neat in real life. Some weeks you'll stay put. That's normal. A bad night's sleep or a skipped meal shows up on the bar.

What about strength standards?

You'll find charts online that say a "beginner" should bench a certain fraction of body weight and an "intermediate" should bench another. Be careful with them. Often you can't tell where the numbers came from or who was measured, and a single ratio can't account for your age, height and training history.

A more useful standard is your own logbook:

• Are your main lifts going up over 4 to 8 weeks?
• Is your form the same or better at heavier weights?
• Are you recovering between sessions?

If all three are yes, you're doing well, whatever a chart says. If your gym runs streaks or a strength board, that can be a fun extra push. Owners can see how that works in our post on gamification in gyms. Just don't let a leaderboard talk you into a sloppy max attempt.

Food and recovery

Strength comes from training plus recovery. Two things matter most:

• Enough protein. Spread it across the day from foods like dal, paneer, curd, eggs, chicken, soya and chana. Work out a daily target for your weight and goal with the protein calculator.
• Enough food overall. It's hard to get stronger while eating very little. Avoid crash diets.

Safety checklist for heavy lifting

• Warm up properly before any heavy set
• Use safety bars in the squat rack, or a spotter for bench
• Don't test a true max until you've trained consistently for a few months
• Stop the set when form breaks, not when you physically can't move the bar
• If you have high blood pressure or a heart condition, check with your doctor before any heavy lifting
• Pain in a joint (not muscle fatigue) means stop and get it checked

The short version

• The NSCA chart: 1 rep = 100%, 5 = 87%, 8 = 80%, 10 = 75%, 12 = 70%
• Estimate your max from a set of 5 to 10 reps, not a true max test
• Epley: weight × (1 + reps ÷ 30). Brzycki: weight × 36 ÷ (37 − reps)
• Beginners train at 8 to 12 RM, 2 to 3 days a week
• Add weight in small jumps (2 to 10%) when you beat your target reps
• Judge yourself against your own logbook, not internet standards

This is general information, not medical advice. If you have a heart condition, high blood pressure, are pregnant or are under 18, check with a doctor and train with a qualified coach before lifting heavy.
