'How much should I bench?' '80 kg of squat, is it a lot or a little?' 'How do I know if I'm using the right weight?'
These are the questions everyone asks themselves and nobody wants to ask out loud. Because the answer feels obvious, 'it depends', but that doesn't help anyone.
The truth is that concrete benchmarks exist to understand where you stand relative to your potential. They're not absolute rules, but they give you a map. Without a map, you're wandering.
In this guide I'll give you the numbers. Strength standards by level and body weight, how to estimate your 1RM without risking injury, and which load to use depending on whether you want to get stronger, bigger, or more endurance-trained. Zero abstract theory, just stuff you can use the next time you walk into the gym.
Strength standards: where do you stand?
Strength standards are benchmarks based on the ratio between the weight you lift (1RM, or the maximum for one rep) and your body weight. They come from decades of data collected on thousands of athletes and give you a realistic idea of your level.
These numbers refer to men. For women, multiply the values by approximately 0.6-0.7.
Flat Bench Press (1RM / body weight)
- Beginner (< 6 months): 0.5x - 0.75x body weight
- Intermediate (6 months - 2 years): 1x - 1.25x body weight
- Advanced (2-5 years): 1.25x - 1.5x body weight
- Elite (5+ years, genetics + dedication): 1.5x - 2x body weight
Example: if you weigh 80 kg and bench 100 kg (1RM), you're at 1.25x, solidly intermediate. Not bad.
Squat (1RM / body weight)
- Beginner: 0.75x - 1x
- Intermediate: 1.25x - 1.75x
- Advanced: 1.75x - 2.25x
- Elite: 2.25x - 3x
Example: 80 kg body weight, squat at 140 kg = 1.75x. Entry to advanced level. Excellent result for a natural lifter.
Deadlift (1RM / body weight)
- Beginner: 1x - 1.25x
- Intermediate: 1.5x - 2x
- Advanced: 2x - 2.75x
- Elite: 2.75x - 3.5x
The deadlift is the exercise where the highest absolute loads are lifted. If your deadlift is below 1x body weight, you're in the very early stages, that's totally normal and progress will be fast.
Military Press (1RM / body weight)
- Beginner: 0.35x - 0.5x
- Intermediate: 0.6x - 0.8x
- Advanced: 0.8x - 1x
- Elite: 1x - 1.35x
The military press is the exercise where the numbers go up the slowest. Pressing your own body weight overhead is a result that takes years.
How to read these numbers
These standards aren't verdicts. They're reference points. They serve to answer the question 'am I progressing?' more objectively than 'I think so.'
Some important clarifications:
- Skeletal leverage matters. If you have long arms, the bench will be harder. If you have short legs, the squat will be easier. The numbers aren't perfect for everyone.
- Body weight influences: the heavier you are, the higher the ratio tends to be (it's easier to have a 1.5x bench at 100 kg than at 65 kg).
- Don't compare yourself to people on steroids. The numbers above are for natural lifters with consistent training.
How to estimate your 1RM without testing it
Testing your real 1RM, loading the maximum possible weight and doing a single rep, is risky and often pointless. Especially if you don't have an experienced partner and years of experience.
The good news: you can estimate it with very good accuracy using a 3-5 rep set and a math formula.
The Epley formula
It's the most used and the most reliable for sets up to 10 reps:
Estimated 1RM = Weight x (1 + Reps / 30)
Example: you do 100 kg for 5 reps on squat.
Estimated 1RM = 100 x (1 + 5/30) = 100 x 1.167 = 116.7 kg
The Brzycki formula
An equally valid alternative:
Estimated 1RM = Weight x 36 / (37 - Reps)
With the same example: 100 x 36 / (37 - 5) = 100 x 36/32 = 112.5 kg
Which formula to use?
Both are accurate, with minimal differences. Epley tends to give slightly higher values, Brzycki slightly lower. The average of the two is probably the closest number to reality.
Tips for an accurate estimate:
- Use a 3-5 rep set. Below 3, technique becomes too variable. Above 10, the formula gets less precise.
- Do a real set, to failure or very close (RPE 9-10). If you stop at RPE 7, the estimate will be too low.
- Use compound exercises. The estimated 1RM is more meaningful on squat, bench, and deadlift than on curls or lateral raises.
On the IRON website you'll find a free One Rep Max Calculator that automatically applies the formulas and generates the percentage table. The IRON app estimates your 1RM in real time every time you complete a set.
Which load to use based on your goal
Now that you know where you stand and how to estimate your 1RM, the question becomes: how much weight do I put on the bar for each set?
The answer depends on the goal of the session.
Maximal strength: 80-100% of 1RM (1-5 reps)
When the goal is to get as strong as possible on a single lift. Few reps, heavy loads, long rest periods (3-5 minutes).
- Who should use it: intermediates and advanced lifters who want to increase their 1RM
- Example: squat 1RM = 120 kg → you work at 96-108 kg for sets of 2-4 reps
- Caution: requires solid technique. Don't improvise loads at 90% if you've been training for 3 months
Hypertrophy (muscle mass): 65-80% of 1RM (6-12 reps)
The range where most people should spend most of their time. Moderate-to-high volume, moderate loads, 2-3 minute rest.
- Who should use it: everyone, from beginners to advanced lifters
- Example: bench 1RM = 100 kg → you work at 65-80 kg for sets of 8-12 reps
- Note: recent research suggests that hypertrophy is achieved across a very wide range (5-30 reps) as long as sets are taken close to failure. But the 6-12 range remains the most time-efficient.
Muscle endurance: 50-65% of 1RM (12-20+ reps)
Light loads, high reps. Useful for accessories, metabolic work, and conditioning.
- Who should use it: as a complement, not as the base of the program
- Example: curl 1RM = 40 kg → you work at 20-26 kg for sets of 15-20 reps
- When it's useful: end-of-session finishers, prehab (face pull, external rotations), muscle groups that respond well to high reps (lateral delts, calves, forearms)
Summary table: % of 1RM → Reps → Goal
- 100% → 1 rep → Max test
- 95% → 2 reps → Pure strength
- 90% → 3-4 reps → Strength
- 85% → 5-6 reps → Strength/Hypertrophy
- 80% → 7-8 reps → Hypertrophy
- 75% → 9-10 reps → Hypertrophy
- 70% → 11-12 reps → Hypertrophy
- 65% → 13-15 reps → Hypertrophy/Endurance
- 60% → 16-20 reps → Endurance
These numbers are averages. Your personal experience may vary: some people do 12 reps at 75%, others do 8. It depends on muscle fiber composition, technique, and the specific exercise.
How to combine load zones in a program
Most well-structured programs don't use a single load zone. The ideal combination depends on the goal:
For hypertrophy with a strength base (the most common and most effective program):
- Main compound exercises: 6-8 reps (75-80% 1RM)
- Secondary compound exercises: 8-12 reps (65-75% 1RM)
- Isolations: 12-15 reps (60-65% 1RM)
For strength with mass maintenance:
- Main exercises: 3-5 reps (85-90% 1RM)
- Secondary exercises: 6-8 reps (75-80% 1RM)
- Isolations: 10-12 reps (65-70% 1RM)
This strategy, called per-exercise autoregulation, lets you develop all muscle qualities in the same session. You start heavy when you're fresh and finish light when you're fatigued. As Mike Israetel recommends: use the rep range that lets you accumulate quality volume at the lowest fatigue cost.
How to choose the weight if you have no idea where to start
It's your first day in the gym. You don't have a 1RM. You don't have benchmarks. How do you choose the weight?
Here's a practical 3-step method:
Step 1: Start light (lighter than you think)
Press the empty barbell (20 kg) on the bench. Do 15 reps. Was it easy? Add 10 kg. Do 10 reps. Still manageable with good technique? Add another 5-10 kg.
Step 2: Find your 'working weight'
The right weight for your sets is the one that lets you do the target number of reps with good technique and feel like RPE 7-8 (meaning 2-3 reps still 'in the tank'). You don't need to go to failure in the first weeks.
Step 3: Track and grow
Once you've found the weight, write it down. Next session you start from there and try to do one more rep, or, if you completed the range, add the smallest possible increment (2.5 kg for upper body, 5 kg for lower body).
In the first 2-3 weeks the loads will go up fast because you're learning the movements, you're not necessarily getting stronger, you're getting more efficient. It's normal and it won't last. Enjoy the moment.
A mistake to avoid: ego lifting
Ego lifting is when you load more than you should to impress someone (often yourself). The signs are clear: reduced range of motion, technique that breaks down, compensation with other muscles, and that suffering face that isn't effort, it's danger.
Nobody in the gym is watching you. And if they are, they're not impressed by your half-squat with 120 kg. They're impressed by someone doing a full squat with 80 kg and perfect technique.
The right load is the one that lets you complete all the planned reps with impeccable technique and 1-3 reps in reserve. If you have to cheat to finish the set, the weight is too high. Period.
Load progression: what to realistically expect
One of the reasons people get demoralized is having unrealistic expectations about the speed of progress.
Here's what's realistic for a man around 80 kg who trains seriously:
First year (beginner)
- Bench: from 40-50 kg to 80-90 kg (+40 kg)
- Squat: from 50-60 kg to 100-120 kg (+60 kg)
- Deadlift: from 60-80 kg to 120-150 kg (+70 kg)
First-year progress is spectacular. You'll miss it.
Second year (intermediate)
- Bench: from 80-90 kg to 95-110 kg (+15-20 kg)
- Squat: from 100-120 kg to 130-150 kg (+20-30 kg)
- Deadlift: from 120-150 kg to 160-180 kg (+30-40 kg)
Year two is still good, but the curve visibly slows down.
Third year and beyond (advanced)
- Bench: +5-10 kg per year
- Squat: +10-15 kg per year
- Deadlift: +10-15 kg per year
At this point every additional kilo is a win. If you add 5 kg to your bench in a year of advanced training, that's an excellent result.
These numbers are for people who train consistently, eat adequately, and sleep enough. If one of these three elements is missing, expect less.
Progression for women
Women follow the same progression curve, with lower absolute numbers but very similar relative progress:
First year:
- Squat: from 20-30 kg to 60-80 kg
- Deadlift: from 30-40 kg to 70-90 kg
- Bench: from 15-20 kg to 35-50 kg
- Hip thrust: from 40-50 kg to 80-100 kg
For women too, the first year is the one with the fastest progress. And for women too, progressive overload is the principle that drives everything.
A common mistake in women's fitness is the fear of 'getting too muscular.' Testosterone levels in women are 15-20 times lower than in men. Building visible muscle mass requires years of heavy and dedicated training, it doesn't happen by accident.
Load myths to debunk
'If you don't feel pain, you're not working hard enough'
False and dangerous. Pain is a warning signal, not a sign of effectiveness. Post-workout muscle soreness (DOMS) isn't a growth indicator, it's just a sign that you did something new. You can have excellent sessions without DOMS and useless sessions with terrible DOMS.
'Women shouldn't lift heavy'
False. Women have the exact same muscular adaptation mechanism as men. They lift less in absolute terms due to hormonal and structural differences, but the principle of progressive overload is identical. And no, lifting heavy doesn't 'bulk up' women, it builds a toned and strong physique.
'After 40 you can no longer increase the loads'
False, with nuances. Recovery capacity decreases with age, so progress is slower and more attention to warm-up and mobility is needed. But progression is absolutely possible. Many natural athletes hit their personal records between 30 and 45 years old.
'Light weights are useless'
False. Recent studies have shown that light loads (30-50% of 1RM) can produce hypertrophy comparable to heavy loads, if the sets are taken to failure. It's not the most time-efficient method, but it works. Light weights are particularly useful for isolations, for people with joint pain, and for deload phases.
Conclusion
The question 'how much weight should I lift?' doesn't have a single answer. But now you have the tools to find your answer: strength standards to understand where you are, formulas to estimate your 1RM without risk, percentages to choose the right load based on the goal, and realistic expectations so you don't get demoralized.
The weight on the bar is a means, not the end. The end is progress over time, and progress requires data. Record your loads, compare them with previous weeks, and make decisions based on real numbers.
IRON calculates your estimated 1RM in real time and shows you exactly how you're progressing over time. But regardless of the tool: start measuring. What you don't measure, doesn't improve.
Frequently asked questions
How do I tell if I'm using a weight that's too heavy?
If you can't complete the minimum rep range planned in the program, if technique visibly breaks down (back rounding in the squat, bouncing in the bench, swinging in the curl), or if you feel joint pain, the weight is too high. Reduce by 10% and work on quality. An ego check now and then is the best investment in long-term gym longevity.
Do I need to go to failure on every set?
No. For most sets, stop 1-3 reps from failure (RPE 7-9). Going to failure on every set piles up too much fatigue and compromises the quality of subsequent sets. Save failure for the last set of isolations, where the injury risk is low.
Is the 1RM calculator reliable?
The estimation formulas (Epley, Brzycki) are accurate within a 5-10% margin of error when you use 3-5 rep sets. With sets over 10 reps, accuracy drops significantly. For a reliable estimate: do a heavy 3-5 rep set at RPE 9-10, plug the numbers into the calculator, and you'll have a solid reference to base your working percentages on.
