Mitchell Hooper: natty or not?
Likely enhanced World's Strongest Man in 2023 and 2026 — the sport's first champion with a physiology degree
Short answer. Verdict: likely enhanced. At the peak physique on this page, Mitchell Hooper is 6'3" (190 cm) and 331 lbs (150 kg) at roughly 18% body fat. That works out to an FFMI of 33.5, 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 | Competition weight, inside his reported 320-340 lb range |
|---|---|
| Height | 6'3" (190 cm) |
| Weight | 331 lbs (150 kg) |
| Body fat | ~18% |
| FFMI | 33.5 — ~25 is the cited natural ceiling |
Era by era (estimated)
| Era | Year | Age | Weight | Evidence | Body fat | FFMI |
|---|---|---|---|---|---|---|
| First World's Strongest Man title | 2023 | 28 | 331 lbs (150 kg) | reported | ~18% | 33.5 |
Note. Competition weight and body fat are estimates inside his reported range, and the verdict is opinion — Hooper has no admission, failed test, or record on file. See the methodology page for how we judge.
Mitchell Hooper is the most credentialed man in strongman: a human kinetics degree from Guelph, a master’s in clinical exercise physiology from Sydney, and his own kinesiology clinic. He won World’s Strongest Man in 2023 and again in 2026, at 6’3” and a reported 320-340 lbs.
The numbers
Hooper is shorter than most of the field and carries a comparable weight, which pushes his FFMI on this page well past the drug-free ceiling the methodology page cites, even at a generous body-fat estimate. Height squared is the denominator; being the compact one in a field of giants is precisely what moves the number.
What is not on the record
No failed test, no sanction, no admission. Strongman’s flagship event has no published anti-doping programme comparable to Olympic sport, so a clean sheet in this sport means considerably less than a clean sheet in one that tests.
Worth saying plainly, because he is unusually open about training science and people read that openness as an answer: explaining your programming in detail is not the same as answering the drug question, and he has not been asked to.
Verdict
Likely-enhanced — on the mass, held as opinion, on the same terms as every other athlete here competing in a sport that does not test.
Common questions
Is Mitchell Hooper natty or on steroids?
This site rates Mitchell Hooper as likely enhanced. 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 33.5, against the ~25 mark cited as the natural ceiling.
Has Mitchell Hooper 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 likely enhanced.
What is Mitchell Hooper's FFMI?
About 33.5. That comes from 6'3" (190 cm) and 331 lbs (150 kg) at roughly 18% body fat, normalized to 1.8 m. Drug-free lifters in the Kouri 1995 study topped out near 25.
