Atlas Stone Strength Standards Calculator
Compare your Atlas Stone strength with Endura's strength standards for men and women at your bodyweight. A useful benchmark for a good one-rep max is our Intermediate standard: approximately 141 lb at 190 lb for a man and 75 lb at 150 lb for a woman.
How does your best lift compare? Enter your bodyweight, the total stone weight used by the calculator, and the reps you completed below. The calculator estimates your one-rep max and shows your strength level for your bodyweight. Use the exercise-specific approved repetition convention.
The calculator compares that estimated one-rep max with the Atlas Stone standards for your sex at your bodyweight. It preserves the calculator's existing equations, thresholds, and input meanings; the benchmark is a comparison target, not a working-set prescription.
Understanding Your Atlas Stone Strength Score
Your Atlas Stone strength score is estimated 1RM divided by bodyweight. The calculator uses the weight from the total stone weight lifted to the defined target, valid Atlas stone weight reps to the defined target, and your bodyweight to create a bodyweight-ratio score. That ratio lets two lifters compare the same exercise without pretending that absolute weight alone tells the full story.
This result is specific to Atlas Stone. A counted rep should lift the round stone from the floor, secure it through the lap or body-contact phase, and weight it to the defined platform or over-bar target without assistance, elevated starts, lower targets, ramps, or carry substitutions. The score is not a general label for every nearby hinge exercise, and it should not be used for Deadlift, Zercher Deadlift, Power Clean, Sandbag Carry, Sandbag weight unless separately specified, Keg weight, Stone Carry, Stone to Shoulder, Front Squat. Those variations may be useful training choices, but they answer a different standards question.
For example, a 200 lb male with a 200 lb estimated 1RM reaches the Advanced boundary for this calculator. A 150 lb female with a 138 lb estimated 1RM reaches the Elite boundary. The same absolute number can land in a different tier when bodyweight changes, which is why the ratio matters.
The most useful reading is practical. Beginner and Novice results usually mean the lifter should make the rep more repeatable before chasing a heavier test. Intermediate results show useful familiarity with the exercise. Advanced and Elite results show strong relative performance only when every counted rep keeps the same range, setup, and finish.
Use the score as a snapshot, then write down the rep details that made the snapshot valid. A later increase means more when the same implement, same setup rule, same range, same support position, and same rep quality were used again.
Atlas Stone Strength Standards
Atlas Stone standards use sex-specific estimated 1RM-to-bodyweight ratios. The lookup tables below convert those ratios into practical targets at common bodyweights. Use the row nearest your bodyweight for a fast check, then use the calculator result for your exact entry.
The tables are rounded to whole pounds for readability. Tier boundaries resolve upward, so meeting the Intermediate, Advanced, or Elite boundary exactly counts as that higher tier. These standards assume the total stone weight lifted to the defined target, valid reps, and no substitutions from related lifts.

Men: Beginner is below 0.500x, Novice begins at 0.500x, Intermediate begins at 0.740x, Advanced begins at 1.000x, Elite begins at 1.280x, and Stretch is 1.520 × bodyweight. Women: Beginner is below 0.340x, Novice begins at 0.340x, Intermediate begins at 0.500x, Advanced begins at 0.700x, Elite begins at 0.920x, and Stretch is 1.100 × bodyweight.
At 200 lb bodyweight, a male lifter needs about 200 lb for Advanced and 256 lb for Elite. At 150 lb bodyweight, a female lifter needs about 105 lb for Advanced and 138 lb for Elite. Treat those as standards for this exact exercise, not as claims about sport ranking or another lift.
How the Atlas Stone Calculator Works
The calculator takes sex, bodyweight, working weight, and reps. A one-rep entry uses that weight directly as estimated 1RM. A multi-rep entry estimates 1RM from the set first, then divides the estimate by bodyweight and compares the ratio with the selected sex table.
Ratio equals estimated 1RM divided by bodyweight. If a lifter at 200 lb bodyweight records a 200 lb estimated 1RM, the ratio is near 1.000x and reaches Advanced. If bodyweight rises while the estimated 1RM stays the same, the ratio falls and the tier can change.
Use one unit family for bodyweight and working weight. Pounds and kilograms both work because the calculator normalizes the math internally. What matters most is that the entered set uses the total stone weight lifted to the defined target and valid Atlas stone weight reps to the defined target that meet the accepted rule.
Multi-rep entries are best when the rep count is challenging but honest. Very high-rep sets can make estimates less precise, especially when fatigue changes range or finish quality. For a standards test, choose a set where the last valid rep still looks like the first valid rep.
The calculator does not add age, sport, equipment-brand, or technique-style multipliers. It answers the specific Atlas Stone question described here, using the same bodyweight-ratio logic as the rest of the standards system.
Elite Atlas Stone Strength Levels
Elite Atlas Stone strength starts at 1.280 × bodyweight for men and 0.920 × bodyweight for women. Stretch benchmarks are 1.520× for men and 1.100× for women, marking unusually strong results inside this standards system.
At 200 lb bodyweight, Elite begins around 256 lb for men. At 150 lb bodyweight, Elite begins around 138 lb for women. Those numbers are impressive only when the entry still reflects the total stone weight lifted to the defined target, valid Atlas stone weight reps to the defined target, and the accepted rep.
Elite lifters should audit reps more strictly, not less. Heavier attempts often tempt shortened range, changed support, body English, or a nearby variation. A bigger number that changes the exercise does not prove a stronger Atlas Stone.
Video is useful at this tier. Side or three-quarter view can show range, start position, path, and finish quality. Review the footage before entering a max set so the calculator records what actually happened.
Training at this level usually alternates clean heavy singles, moderate technical work, and targeted assistance. The goal is to make the strict rep durable rather than turn every session into a max attempt.
For fair comparisons, keep the target height, stone diameter, tacky policy, and platform surface consistent. A heavy stone to a lower platform is not the same standard as the same weight to the prescribed target.
Atlas Stone Strength Compared to Other Lifts
Comparisons are useful because they explain why standards differ. Atlas Stone sits near related movements, but the ratios should not be copied because the implement, support, range, path, and finish rule are specific to this calculator.
| Related movement | Comparison purpose | What the gap can reveal |
|---|---|---|
| Barbell Deadlift | closest neighboring standard | A higher Atlas Stone score can show skill in this exact setup, while a lower score points to the constraint this calculator isolates. |
| Zercher Deadlift | same family contrast | If the related lift is far ahead, the limiting factor is often range, bracing, grip, or strict finish quality here. |
| Sandbag Carry | equipment contrast | If this score is far ahead, confirm the set did not drift into a disallowed variation. |
| Barbell Power Clean | range and control comparison | The comparison is useful because the bodyweight-ratio math is shared while the accepted rep is different. |
| Paused Front Squat | heavier strength ceiling | A similar tier can suggest balanced development, but it still does not make the two entries interchangeable. |
| Trap Bar Deadlift | technique transfer check | Use the gap to choose training work instead of forcing one result to predict the other. |
If a related lift is much stronger, look for the one constraint unique to Atlas Stone: range, support position, grip, bracing, or finish control. If Atlas Stone is much stronger, confirm that the set did not become one of the disallowed variations.
Also separate implement families before drawing conclusions. A barbell version may reward a straighter path and heavier total weight, a dumbbell version may make grip and wrist position the limiter, a cable or machine version may remove some bracing demand, and a squat, press, row, curl, or extension pattern belongs in a different standards family entirely.
The goal is not to make all badges match. The goal is to identify whether the difference comes from true strength, a technical bottleneck, or a substituted movement that only looks similar on paper.
Milestones in Atlas Stone Strength
Milestones turn tier ratios into training targets. They are most useful when they are tied to bodyweight and rep quality instead of vague goals such as strong or heavy.
| Milestone | Example target | Why it matters | Next focus |
|---|---|---|---|
| First valid floor-to-target Atlas stone weight | 3 to 5 clean reps at a repeatable training weight | Shows the lifter can follow the accepted rule before a max test | Keep setup identical across sets |
| Novice boundary | Men near 100 lb; women near 51 lb | Creates a first bodyweight-ratio benchmark | Build range and control |
| Intermediate boundary | Men near 148 lb; women near 75 lb | Shows the lift is no longer just familiar | Address the main limiter |
| Advanced boundary | Men near 200 lb; women near 105 lb | Marks strong relative performance for this exercise | Use smaller jumps and more video review |
| Elite boundary | Men near 256 lb; women near 138 lb | Shows high-level strength in the exact standard | Protect strict rep quality |
| Stretch benchmark | Men near 304 lb; women near 165 lb | Represents an unusually strong score in this calculator | Retest sparingly and recover well |
| Five-rep practice target | Use a set that estimates near 148 lb for a 200 lb male or 75 lb for a 150 lb female | Builds a cleaner estimate before a heavier test | Keep every rep visually identical |
| Ten percent improvement target | Move a 148 lb estimate toward 163 lb, or a 75 lb estimate toward 83 lb | Gives a concrete block goal without requiring a new tier | Retest only when the same rule survives |
Milestones should never override the accepted rep. A lifter who reaches the Advanced number with a substituted movement has not reached the Advanced Atlas Stone milestone. A lifter who barely misses with excellent reps is often closer to durable progress than the badge alone suggests.
Related Strength Standards Tools
Related tools place Atlas Stone inside a broader strength map. They help explain why a lifter may be strong in one nearby movement and average in another. They are not substitutions, and their scores should stay separate from the current calculator.
- Barbell Deadlift is the closest neighboring benchmark for many lifters, but the accepted range and finishing rule stay separate from Atlas Stone. Compare it after a clean Atlas Stone test to see whether this exact setup is the limiter.
- Zercher Deadlift gives a same-family contrast where equipment and support can change the result quickly. A gap often points to grip, range, bracing, or skill rather than one universal strength ceiling.
- Sandbag Carry is useful when the current score feels surprising. Check it only after the Atlas Stone reps are valid, then use the difference to choose assistance work.
- Barbell Power Clean can show whether a heavier-looking movement is actually testing a different constraint. Keep the entries separate so a substituted rep does not inflate this calculator.
- Paused Front Squat helps frame broader strength without replacing the Atlas Stone standard. If it is far ahead, audit the exact range and finish required here.
- Trap Bar Deadlift offers a technique-transfer check. Similar tiers suggest balanced development, while different tiers can reveal where the path, support, or rep count breaks down.
- Romanian Deadlift belongs in the comparison set because the name may sound close while the accepted rep is not identical. Use the tool as context, not as a replacement entry.
- Barbell Clean and Press gives another bodyweight-ratio lens for the same training neighborhood. The most useful note is why the gap exists: range, depth, path, bracing, or control.
Use these tools after you have a valid Atlas Stone result. If the comparison changes your interpretation, write down the likely reason: range, grip, path, support, bracing, lockout, depth, or control. That note is often more useful than the badge alone.
