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.
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. Hybra 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.
Each pillar is the average of its scored exercises, multiplied by a coverage factor (0.90–1.00). Logging all exercises in a pillar gives full value. Logging just one gives 90% — a small discount that discourages cherry-picking your single best lift.
Athletics uses count-weighted sub-pillars. Power and Bodyweight Strength are averaged by how many exercises you logged in each — not a flat 50/50. Log 3 power exercises and 1 bodyweight: power carries 3× the weight in the sub-pillar average.
All three pillars are required for a ranked tier. A partial profile (missing one or more pillars) is scored but capped at Baseline — HYBRA is a hybrid system and tiers reflect hybrid output. Individual scores are capped at 100 before any averaging. The Confidence indicator reflects how many of 19 exercises are documented.
Age is applied with three separate tracks. Strength and bodyweight exercises, explosive power (sprint/jumps), and endurance each follow a different physiological decline curve. A 50-year-old powerlifter and a 50-year-old sprinter age differently — the system reflects that. Full tables are in the Adjustments tab.
Distribution among competitive recreational hybrid athletes (18+ months structured training). The untrained adult population sits below Novice — most people score below 30.
Two athletes whose publicly documented competition results place them in estimated World Class range. Neither has completed all 19 exercises within this system — these are estimates derived from competition records only.
Estimates only. A full Hybra Score requires all 19 exercises logged within the system.
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.

Gym Pillar Score = average of logged gym exercises × coverage factor (0.90 at 1 exercise, 1.00 at all 5).
Two separate sub-pillars, combined by count-weighted average. Power & Explosiveness (jumps, sprint) and Bodyweight Strength (pull-ups, push-ups, dips, L-sit) are scored independently. Each sub-pillar is weighted by the number of exercises logged in it — a specialist strong in one and weak in the other cannot inflate the combined score.
Uses BW^0.50 — a middle-ground exponent — because a static hold requires active force production against gravity, scaling closer to strength (BW^0.67) than pure geometry (BW^0.33).
Broad jump uses BW^0.33 — projectile physics, where mass meaningfully affects horizontal distance. Box jump uses BW^0.20 — height is less mass-dependent; larger athletes can produce more absolute force, so the body weight penalty is smaller.
100m sprint (lower time = better)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.

Different physiological systems age at different rates. A single age multiplier applied to all exercises is a scientific compromise — HYBRA uses three distinct tracks derived from WMA 2023 age grading data and published sports science.
STRENGTH — Gym lifts + Bodyweight exercisesBased on Masters powerlifting relative strength norms (809,986 competition entries, PubMed 2024). Peaks age 32–34. Moderate decline — technique and neural efficiency partly offset hormonal losses.
| Age | Multiplier |
|---|---|
| ≤ 34 | × 1.000 |
| 35–39 | × 0.974 |
| 40–44 | × 0.942 |
| 45–49 | × 0.902 |
| 50–54 | × 0.854 |
| 55–59 | × 0.797 |
| 60+ | × 0.730 |
Fastest-declining track. Neuromuscular power peaks ~age 25 and drops steeply. Based on WMA 2023 sprint/jump factors and Pickering, Hicks & Kiely (2021) — Why Are Masters Sprinters Slower?

| 54–58 | × 0.680 |
| 59+ | × 0.600 |
Based on WMA 2023 distance running factors. VO₂max declines ~1%/year from age 30–35. Economy losses add slightly more from age 50+.

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.
| Condition | Adjustment |
|---|---|
| Per 10 cm from sex average (M: 175 cm, W: 162 cm) | ±0.02 — capped at ±0.06 total |
| Man at 195 cm | −0.04 · penalty for range of motion advantage |
| Man at 165 cm | +0.02 · bonus for mechanical disadvantage |
When you log a run time, HYBRA displays an estimated VO₂ max using the Daniels-Gilbert formula (1979), one of the most validated performance-to-aerobic-capacity models in exercise science. This is a "functional VO₂ max" — it captures both aerobic capacity and running economy, unlike lab testing which measures oxygen uptake alone. Source: Daniels & Gilbert, Oxygen Power (1979). Formula: best available run (5K or 10K preferred).
Where V = velocity in m/min, T = time in minutes. This is a display-only metric — it does not affect your HYBRA score. It is shown because a 16:00/5K athlete and an 18:30/5K athlete scoring the same HYBRA endurance sub-score might have meaningfully different aerobic ceilings.
Entering your body fat % enables display of your Lean Body Mass (LBM) alongside your VO₂ max. LBM is shown as informational context — it does not currently modify your HYBRA score. Why not? The legendary constants were calibrated against total bodyweight competition data. Substituting LBM without recalibrating those constants would introduce systematic error. LBM-adjusted scoring is planned for a future update when sufficient body-composition-linked performance data is available.
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.
