Sergi Constance: natty or not?
Uncertain Spanish fitness model and IFBB Men's Physique pro; Zeus in the Justice League Snyder Cut
Short answer. Verdict: uncertain. At the peak physique on this page, Sergi Constance is 6'1" (185 cm) and 209 lbs (95 kg) at roughly 12% body fat. That works out to an FFMI of 24.1, against the ~25 mark cited as the natural ceiling.
No official record settles this. What follows is opinion and analysis based on public numbers — how we judge.
The numbers (estimated)
| Peak physique | His established fitness-model form, around 209 lbs |
|---|---|
| Height | 6'1" (185 cm) |
| Weight | 209 lbs (95 kg) |
| Body fat | ~12% |
| FFMI | 24.1 — ~25 is the cited natural ceiling |
Era by era (estimated)
| Era | Year | Age | Weight | Evidence | Body fat | FFMI |
|---|---|---|---|---|---|---|
| Established form | 2015 | 27 | 209 lbs (95 kg) | reported | ~12% | 24.1 |
Note. Sergi Constance has implied natural status and no test, record, or admission exists either way. Every number below is a reported figure or our own photo read, not a measurement.
Sergi Constance is a hard case for an honest method: a 209-lb (95 kg), 6’1” (185 cm) IFBB Men’s Physique pro and fitness model whose verdict swings entirely on a body-fat estimate nobody can verify.
The math, both ways
Read him the way fan estimators do — 209 lbs at 14-16% — and his FFMI lands around 23, a good natural for a man who credits years of consistent dieting and training. Read his shoot-condition photos the way this site reads photos — the same weight nearer 10-12% — and he computes to 24.5-25, on the ceiling. There is no dated baseline, no documented transformation timeline, and no era-to-era rate to price: his entire public life is the finished physique. That absence of a timeline is itself the reason this page can’t do better than a coin-flip band.
The context is the usual fitness-model ledger: an untested pro division, an image that is the income, and — on the other side — a frame and career (including playing Zeus for Zack Snyder) that select for exactly the genetics that make natural ceilings generous.
Verdict
Uncertain. The honest range of his numbers straddles the ceiling, and no timeline exists to break the tie. The tripwire in both directions: a verified body composition, or any documented era-to-era gain in his mid-30s — growth from here would resolve it the way growth at that age always does.
In their words
“Low-intensity cardio has worked well for me. I do cardio 3x a week for 30-45 minutes on the treadmill on an incline. Cardio is great for burning fat and improving keeping fit.”
Common questions
Is Sergi Constance natty or on steroids?
This site rates Sergi Constance as uncertain. That is an opinion drawn from public numbers, not a statement of fact: the peak physique on this page works out to an FFMI of 24.1, against the ~25 mark cited as the natural ceiling.
Has Sergi Constance ever failed a drug test or admitted to using PEDs?
Nothing of the sort turned up in the sources on this page. Had it, the verdict would read confirmed instead of uncertain.
What is Sergi Constance's FFMI?
About 24.1. That comes from 6'1" (185 cm) and 209 lbs (95 kg) at roughly 12% body fat, normalized to 1.8 m. Drug-free lifters in the Kouri 1995 study topped out near 25.
