One number from 0–100. Strength, power, endurance — each pillar scored against the same standard, adjusted for bodyweight and age. A 65 kg runner and a 95 kg powerlifter land on the same scale. Every formula is documented below, nothing omitted.

WHY BODYWEIGHT IS IN EVERY FORMULA

A 100 kg athlete who deadlifts 200 kg has lifted 2× bodyweight. A 60 kg athlete who deadlifts 180 kg has lifted 3×. Relatively, the 60 kg athlete is stronger. A raw leaderboard rewards mass, not output. Apex corrects for that.

Every formula divides your raw number by a bodyweight factor before scoring. This is allometric scaling — the same method used by Concept2 rowing rankings and World Masters Athletics. The mathematics of fair comparison.

HOW THE THREE PILLARS COMBINE
Apex Score = ( Gym Pillar + Athletics Pillar + Endurance Pillar ) ÷ 3

Each pillar is the average of its scored exercises. Athletics averages two sub-pillars (Power, Bodyweight Strength) before entering the final average. Individual scores are capped at 100 before any averaging.

19 exercises maximum, none mandatory. A single pillar gives a valid Apex Score. Blank fields are excluded from all averages — they do not penalise. The Confidence indicator reflects how many of 19 are documented.

Score 100 = 90th percentile of specialist competitors per domain (~99th percentile of hybrid athletes). Score 50 = 50th percentile of competitive recreational hybrid athletes with 18+ months of structured training. The standard is calibrated, not arbitrary.

THE DSS MODEL

DSS = Derivative Strength-Scaling. An exponential curve mapping how lifting ability grows with bodyweight. The key insight: bigger athletes don't get proportionally stronger — a person twice as heavy can't lift twice as much. Inspired by IPF formula research, independently calibrated to hybrid athletes.

FORMULA
Step 1 — Bodyweight-adjusted coefficient
GL_Coef = Load_kg ÷ ( A − B × exp(−k × BW_kg) )
Load_kg
The weight you lifted. E.g. 180 kg deadlift → Load_kg = 180.
BW_kg
Your bodyweight in kg — the variable that makes comparison fair.
A
Theoretical max lift at infinite bodyweight (the asymptote). Men: 1199.7 kg · Women: 610.3 kg. Derived from real competition data.
B
Drop-off factor — how much weaker a very light athlete is vs a heavy one. Men: 1025.18 · Women: 1045.59.
k
Steepness of the bodyweight curve. Men: 0.00921 · Women: 0.03048. Higher k = bodyweight matters more. Women's is higher because female strength scales more steeply in competition data.
GL_Coef
The result: your bodyweight-adjusted strength number. Two athletes with the same GL_Coef are equally strong relative to their body.
Step 2 — Score against the Legendary level
Score = ( GL_Coef ÷ Legendary_Const ) × 100
Why the 90th percentile? Powerlifters specialise exclusively in lifting. A hybrid athlete who also trains endurance and power cannot reasonably match the top 1% of pure lifters. The Legendary threshold is set at the 90th percentile of powerlifters — equivalent to approximately the 99th percentile of hybrid athletes.

Pillar 2 · 7 exercises · 2 sub-pillars
Athletics
Power: Broad Jump · Box Jump · 100m Sprint  ·  Bodyweight: Pull-ups · Push-ups · Dips · L-Sit

Two separate sub-pillars, averaged into one. Power & Explosiveness (jumps, sprint) and Bodyweight Strength (pull-ups, push-ups, dips, L-sit) are scored independently. A specialist strong in one and weak in the other cannot inflate the combined score.

Athletics Pillar = ( Power Sub-Score + Bodyweight Strength Sub-Score ) ÷ 2
SUB-PILLAR 1 — BODYWEIGHT STRENGTH
Rep-based (pull-ups, push-ups, dips)
Score = ( Reps ÷ BW_kg^0.67 ) ÷ Legendary_Const × 100
BW_kg^0.67
Bodyweight to the power of 0.67. At 80 kg → ≈19.9. Why 0.67? A.V. Hill (1950): muscle force scales with cross-sectional area, which scales at roughly mass^0.67. A heavier athlete gets credit for extra muscle — but not fully, because they're also lifting that extra mass.
Reps ÷ BW^0.67
Your rep-adjusted coefficient. Same value = equally capable relative to body size regardless of weight.
L-Sit hold (time-based)
Score = ( Seconds ÷ BW_kg^0.33 ) ÷ Legendary_Const × 100

Uses BW^0.33 — a smaller exponent — because static holds scale differently from dynamic movements against gravity.

SUB-PILLAR 2 — POWER & EXPLOSIVENESS
Jumps (broad jump, box jump)
Score = ( Distance_cm ÷ BW_kg^0.33 ) ÷ Legendary_Const × 100

Jumping scales weakly with bodyweight — more force but more mass to project. BW^0.33 captures the modest effect.

100m sprint (lower time = better)
Score = Legendary_Const ÷ ( Time_sec × BW_kg^0.111 ) × 100

Smallest exponent in the system: 0.111. Sprint speed has the weakest link to bodyweight of any exercise. The formula is also inverted — lower time sits in the denominator so faster athletes score higher.

KLEIBER'S LAW
Kleiber's Law (1932): metabolic rate scales with mass^0.75. Di Prampero (1986) applied this to locomotion — the energy cost of running scales at approximately mass^0.222. Concept2 uses this same exponent for their bodyweight-adjusted rowing rankings. It is among the most validated adjustments in endurance sport.
FORMULA
ALL RUNNING AND SWIMMING
Score = Legendary_Const ÷ ( Time_sec × BW_kg^0.222 ) × 100
Time_sec
Your time in seconds. A 22:00 5K = 22 × 60 = 1320 seconds.
BW_kg^0.222
At 80 kg → ≈2.77. A heavier runner gets a small adjustment because carrying more weight costs more energy. Small exponent (0.222) because endurance is mostly about aerobic capacity, not mass.
Inverted
Lower time = better, so time sits in the denominator. Faster → smaller denominator → higher score.

AGE FACTOR — WMA_f

Peak output occurs between ages 24–31. After that, physiological decline is measurable regardless of training volume. The age factor is a post-calculation multiplier giving older athletes credit for real-world performance decline. Values sourced directly from World Masters Athletics official age-grading tables (2023).

HEIGHT FACTOR — GYM ONLY

Range of motion is shorter for smaller athletes in barbell lifts. This confers a mechanical advantage. The correction is minor, capped at ±0.06, and applied only to the Gym pillar. It is not a meaningful enough factor to influence tier placement.

SIX TIERS.
ONE STANDARD.

Your score places you in one of six tiers. Tiers are gates, not labels — each demands minimum output across all three pillars. A 95 kg lifter with no running score cannot hold Elite. The standard is fixed. Either you meet it or you don't.
