What this result does not account for
- Strength standards are conventions, not measurements. Different sources place the boundaries differently, sometimes by a fifth of a bodyweight multiple.
- The two-thirds scaling law assumes geometric similarity, which real bodies only approximate. Limb lengths and leverages vary considerably.
- Standards shown are for men. Upper-body figures do not transfer to women.
- Body composition is ignored. Two athletes at the same bodyweight with very different body fat percentages are not comparable.
- Calisthenic load fractions are averages and shift with body proportions and exact technique.
In short: Relative strength is simply lift ÷ bodyweight. A 140 kg squat at 70 kg bodyweight is 2.00× — solidly intermediate. But the ratio is biased against size, and that is worth understanding before you compare yourself to anyone. Muscle force follows cross-sectional area, which scales as roughly mass^(2/3), not mass. So a geometrically similar 110 kg lifter — identical relative muscularity — manages 189 kg, which is only 1.72×. Same athlete, smaller number. That bias is exactly why competition uses DOTS and Wilks instead.
Formula
[('strength ratio', 'Lift divided by bodyweight. Excellent for tracking yourself, poor for comparing across sizes.'), ('mass^(2/3)', 'The scaling law. Area grows as the two-thirds power of volume, and muscle force follows area.'), ('geometrically similar', 'Two athletes with the same proportions and the same relative muscularity, differing only in size.'), ('movement fraction', 'The share of your bodyweight a calisthenic exercise actually loads — 64% for a push-up, 100% for a pull-up.')]
Worked Example
- Divide the lift by your bodyweight. That is the ratio, and it is the number most training standards are written in.
- Find the standard for that specific lift. A 1.5× deadlift and a 1.5× overhead press are worlds apart.
- Adjust for size before comparing. Scale by the two-thirds power of the mass ratio to see what an equally muscular athlete would post.
- Use DOTS for real comparisons. Allometric scoring exists precisely because the raw ratio is size-biased.
A 70 kg lifter squatting 140 kg is at 2.00× bodyweight, which is intermediate heading toward advanced. A geometrically similar 110 kg lifter — no more and no less muscular for their frame — would squat about 189 kg, which is a larger lift but only 1.72×. The same athlete scaled up looks weaker by the ratio and stronger on the bar. Meanwhile that 70 kg lifter's push-up loads only about 45 kg, which is why calisthenics alone plateau.
Strengths & Limits Of This Model
Where this engine is strong
- Explains the size bias in the ratio rather than presenting it as neutral.
- Uses lift-specific standards instead of one generic table.
- Quantifies what calisthenic movements actually load.
- Defers competitive comparison to DOTS rather than duplicating it.
Where it stops
- Cannot account for individual leverages, which affect some lifts far more than others.
- Standards are men's benchmarks and need adjusting for women on upper-body lifts.

Methodology & Editorial Standards
The strength ratio is the lift divided by bodyweight, and it is classified against widely published training standards for the specific lift selected, since standards vary greatly between movements. The size-adjusted comparison applies allometric scaling: muscle force is proportional to cross-sectional area, which for geometrically similar bodies scales as mass to the two-thirds power, so an equally muscular athlete at a different bodyweight is predicted to lift the original weight multiplied by the mass ratio raised to two-thirds. This is presented to explain why raw ratios disadvantage larger lifters, and the tool explicitly defers competitive comparison to allometric scoring systems such as DOTS rather than attempting its own. Calisthenic loads use published estimates of the proportion of bodyweight supported in each movement, with any added weight summed on top. Standards are stated as men's benchmarks with a note that upper-body figures do not transfer to women.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Bodyweight Strength Calculator — 9 Expert FAQs
9 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is a good strength to bodyweight ratio
It depends entirely on the lift. Broadly accepted intermediate standards for men are about 1.75× bodyweight for a back squat, 1.35× for a bench press, 2.10× for a deadlift, 0.80× for an overhead press and 1.15× for a barbell row. Advanced runs to roughly 2.25×, 1.75×, 2.75×, 1.00× and 1.50×. Women typically post lower ratios on upper-body lifts and much closer ones on the squat and deadlift.
Why do smaller lifters have better bodyweight ratios
Because muscle force depends on cross-sectional area, and area grows as roughly the two-thirds power of mass rather than in proportion to it. A lifter who is twice as massive but identically proportioned has only about 1.59 times the muscle cross-section, so they lift about 1.59 times as much while weighing twice as much — a lower multiple. Nothing about them is weaker. The arithmetic simply over-corrects for size.
Is a 2x bodyweight squat good
Yes — it sits solidly in the intermediate band for men and is a genuinely respectable lift that most gym-goers never reach. It is short of the advanced 2.25× standard. Bear in mind the number means different things at different bodyweights: 2× at 60 kg and 2× at 110 kg represent quite different amounts of muscle, with the heavier lifter having rather more.
How much of my bodyweight does a push-up lift
About 64% in a standard push-up, because your feet carry the rest. Elevating the feet raises it to roughly 75%. A pull-up or dip is the full 100%, an inverted row around 60%, a bodyweight squat about 70%, a pistol squat 85% and a plank 60%. This is why push-ups build endurance long after they have stopped building maximal strength: the load is capped at a fraction of a bodyweight that is not increasing.
Should I lose weight to improve my strength ratio
Rarely, and never as the primary strategy. The ratio has a numerator and a denominator, but cutting bodyweight costs you strength as well — you lose some muscle along with fat, and leverage and stability suffer. Adding weight to the bar improves the ratio without any of those costs. Cut for a weight class or for health, not to flatter a number.
What is the difference between this and DOTS
A bodyweight ratio divides by mass, which assumes strength scales linearly with size. It does not. DOTS fits a curve to the real relationship between bodyweight and expected total, which makes it a fair comparison across weight classes and the reason it is used in competition. Use the ratio to track yourself over time and DOTS to compare yourself with other people.
Do these standards apply to women
The lower-body ones roughly do; the upper-body ones do not. Women typically reach squat and deadlift multiples close to men's given equivalent training, but bench press and overhead press standards run considerably lower, largely because of differences in upper-body muscle distribution. Treat the figures here as men's benchmarks and adjust the pressing standards down.
How do I work out my ratio if I cannot do a single
Estimate a one-rep max from a set you can complete, then divide that by bodyweight. Any set of ten reps or fewer gives a reasonable estimate, and the one rep max calculator applies several published formulas and shows the spread between them. Testing a true single is unnecessary for this purpose and carries more risk than it is worth for most lifters.
Why is the overhead press standard so much lower
Because it uses far less muscle and offers no leg drive, no bench to brace against and a much longer range of motion under an unstable load. A strict 1.0× bodyweight overhead press is an advanced lift that most lifters never achieve, whereas a 1.0× deadlift is a beginner milestone. Comparing ratios across lifts tells you nothing — only comparing within a lift is meaningful.
