Two lifters pull the same weight. One has short femurs and a long torso. The other is built the opposite way. The physics are completely different — but the scoreboard shows the same number. STATURE calculates the actual mechanical demand on your body, so you can stop comparing absolute numbers and start understanding real performance.

You've seen it: two people squat the same bar weight and one grinds through it while the other breezes. Body proportions — femur length, torso-to-leg ratio, arm span — change how much mechanical work your muscles actually perform per rep. Longer femurs mean more hip moment arm, more quad demand, more torque. Shorter arms mean a longer pull. Programming by percentage alone ignores all of this. STATURE puts the physics on screen so you can finally see what your body is actually doing.
See the actual mechanical demand of your lifts relative to body weight and proportions. Compare any two builds side-by-side to understand who's working harder at the same absolute load.
Sumo or conventional? High bar or low bar? Wide stance or close? STATURE ranks every variant by biomechanical fit for your specific proportions — not generic recommendations.
Submit meet totals from multiple lifters and see biomechanical rankings alongside official rankings. Identify who outperformed their proportional potential — and who has more in the tank.
Map your body across all six major lifts. Discover which movements your proportions naturally favor and where you're fighting your own levers — so you can train smarter, not just harder.
STATURE uses your height and sex to derive segment lengths (femur, tibia, torso, arms) from validated anthropometric ratio tables, then runs a full kinematic chain calculation for each lift. The demand factor expresses how much work your muscles perform per kilogram lifted, relative to what an average-proportioned lifter of the same height would produce.
Significantly. Femur length alone can change hip moment arm by 20–30%, which directly scales quad and glute demand in the squat. Arm length affects how far you pull in a deadlift. Torso length influences bench arch potential and OHP stability. These aren't marginal differences — they explain why two lifters at the same weight class can have vastly different lift profiles.
Yes. The variant optimizer runs every stance combination for your proportions and ranks them by biomechanical efficiency. Lifters with longer femurs often see a clear sumo advantage; those with shorter legs and longer torsos may favor conventional. STATURE shows you the physics behind the recommendation.
Enter your competitors' heights, weights, and totals on the Meet page. STATURE adjusts each total for biomechanical demand and produces a normalized ranking alongside the official one. This tells you who's overperforming relative to their levers — and gives you context for your own performance ceiling.
The core biomechanics calculations apply to equipped lifting — the same levers are at work. However, STATURE does not currently model suit/shirt carryover specifically. The demand factor and variant rankings are still useful for understanding proportion-based strengths and weaknesses even in equipped competition.
The core comparison tool is free. STATURE Pro ($49 lifetime) unlocks the full build profile, meet analyzer, variant rankings, training log, and custom segment inputs. There are no subscriptions — one payment, lifetime access.
