If you have seen a very lean, muscular man on your feed captioned “under 5% body fat,” that is probably Shaun Rez. He goes by Mr. FIVEO online and runs a fitness brand built around that number.
Most pages about him repeat the same few lines and never check them against each other. His reported weight, his birth date and his diet all vary depending on where you look.
This guide sorts what is documented from what is self-reported, and flags what nobody has confirmed. It covers his age, height, weight, nationality, relationship status, workout, career and bio, updated for October 2026.
Key Takeaways
• Shaun Rez is reportedly 44, born February 13, 1982, but that date comes from a single biography site.
• He lists himself as 6 ft tall, and his own bios give his weight as 198 lbs and 205 lbs on different pages.
• No wife, spouse or partner has been publicly confirmed.
• He built the FIVEO LIFE brand, appeared in the 2024 film Prepare to Die, and joined Rampage Jackson on a podcast the same year.

Who Is Shaun Rez?
Shaun Rez is an American fitness model and coach who built his following on one claim: that he stays below 5% body fat year-round, naturally. His own pages describe him as a content producer, director, actor and fitness model, and his social bios list Huntington Beach, California as his home.
The name needs a note. Competitor pages call him “Shaun Fiveo Rez,” but “Fiveo” is a nickname built from his brand. His own FIVEO LIFE site is signed “Shaun Rezaei,” which suggests Rez is a shortened or professional form of that surname. He has not publicly explained the change in anything found for this article, so treat Rezaei as a strong clue rather than a confirmed legal name.
He is not the same person as any of the many other Shauns who share search results with him, such as the actors, footballers and musicians who appear for a plain “Shaun” search. His handle on Instagram and TikTok is @shaun_rez, which is the quickest way to confirm you have the right person.
Shaun Rez Age and Birthday
Shaun Rez was reportedly born on February 13, 1982, which makes him 44 years old as of October 2026. That birth date appears on one biography site, which also notes it falls on 24 Bahman in the Persian calendar. The date and the calendar conversion agree with each other, but that is a consistency check, not independent proof.
One thing competitors get wrong: the main competing page says he is 43 “as of 2026.” That was only true before his February birthday. If the 1982 date is right, he turned 44 earlier this year.
Nothing he has posted contradicts it. A February 13 birthday would make him an Aquarius, and some of his TikTok posts use Aquarius hashtags. Others use over-40 fitness hashtags. That fits a man in his forties, though it does not prove an exact date.
He has not confirmed his birthday in any interview or post found for this article, so “reportedly 44” is the honest wording.
Shaun Rez Nationality and Background
Shaun Rez is American. A biography site describes his roots as Iranian Persian, and his Instagram display name reportedly carries both a US and an Iran flag. He has not, in anything found for this article, given an interview about his family background.
That limit matters because some pages fill the gap with detail. They describe how his father pushed him to keep moving and how his mother shaped his outlook. None of that is tied to a quote, interview or post, so it is not repeated here.
Verified or consistent across sources:
• He is based in Huntington Beach, California, according to his own Facebook profile.
• His brand and name point to Persian heritage, which fits the Rezaei signature on his website.
• He has not shared details about siblings or childhood.
Shaun Rez Height and Weight
Shaun Rez gives his height as 6 ft (about 183 cm) in his social bios. Nobody has independently measured him, so this is self-reported.
His weight is the stat that changes the most. Three figures circulate:
| Source | Weight |
| Threads and one Facebook bio | 198 lbs (about 90 kg, or 14 st 2 lb) |
| A second Facebook page | 205 lbs (about 93 kg, or 14 st 9 lb) |
| A biography site | 185 lbs (about 84 kg, or 13 st 3 lb) |
Why His Reported Weight Varies
A gap of 20 lbs across his own bios and a competitor can look like a mistake, but there are ordinary explanations. His own pages were probably written at different times, and his weight naturally moves with training phases, as one competitor also notes. A bio written years ago and never updated will show an older number.
The competing 185 lb figure is the outlier, since it matches none of his own pages. The safest summary is that he is 6 ft and roughly 198 to 205 lbs by his own account. Treat any single exact number with caution, including the ones here.
Shaun Rez Career: From Fitness Modelling to Film
Shaun Rez’s career has three strands: fitness modelling and coaching, brand promotion, and a small amount of screen work. None of it has been covered by a major outlet, so this section relies on his own pages, a podcast listing, and film databases.
He first got attention as a fitness model, posting training and physique content on TikTok, Instagram and YouTube (his channel is FiveoLifeTV). His TikTok account lists 227.6K followers, and his Threads page lists about 85.5K. These counts change often, so check the accounts for current figures.
He also promotes products on his own platforms, including FATHERSONS menswear, ICONMEALS meal prep (which he says he has used for over five years) and The Virtu custom leathers. His site attaches a discount code to each of them, which is a standard affiliate arrangement worth knowing about when reading his recommendations.
Prepare to Die (2024)
Shaun Rez is listed in the cast of Prepare to Die, a martial-arts revenge film from The Asylum about a young man who trains to avenge his murdered family. The cast also includes Michael Madsen, Lorenzo Lamas and Quinton “Rampage” Jackson.
His role is not visible in the listings that could be accessed. The release date also varies by database: IMDbPro gives January 12, 2024, while another film database lists September 18, 2024. Check the title page for the date you need.
The HJR Experiment Appearance with Rampage Jackson
On February 15, 2024, Rez appeared on The HJR Experiment podcast in an episode titled “Rampage and Shaun Rez on Guns, Fasting, and Going Sober.” The 49-minute episode introduces him as Rampage Jackson’s personal trainer.
The episode description says he opened the discussion with his views on nutrition. He argued that protein should come from varied sources, called steak the most complete protein, said he avoids fruit because of its sugar, and said he prefers supplements. The title also mentions going sober, but the listing does not say that Rez himself has quit anything, so the article does not claim it.
A separate report by EssentiallySports shows the working relationship from the other side. It quotes Rez commenting on a viral clip of Rampage training with his son while on a 24-hour fast.
What Is FIVEO LIFE?
FIVEO LIFE is the fitness brand Shaun Rez runs under the Mr. FIVEO name. The “FIVEO” part is a play on 5%: the brand’s goal is to live below 5% body fat as a long-term lifestyle rather than a short diet. His site is aimed at two groups. One is physique competitors who want to stay stage-ready all year without the usual bulk-and-cut cycle. The other is ordinary people who adopt the lifestyle and benefit even if they never reach 5%.
The site sets out three goals: lower unnecessary body fat, build natural lean muscle, and raise daily energy and productivity. It lists eight “ingredients” to get there:
1. More effective cardio
2. Cutting unnecessary daily carbs and fat
3. More high-quality natural protein
4. More nutrient-dense greens
5. Quality vitamins and supplements
6. Applying necessary fats and carbs deliberately
7. Weight training aimed at long-term muscle growth
8. Fitting nutrition around daily routine and training
The site says working people and CEOs have used his methods. It gives no names, results or timeframes, so that claim is unverified. Anyone who wants his full programme is directed to a contact form labelled “Get Coached by Mr. FIVEO.” No public price list or published programme turned up in the research for this article.
The “Under 5% Body Fat” Claim, Explained
His brand rests on a number, so it helps to know what the number means. The American Council on Exercise (ACE) places men’s essential fat at 2 to 5%, the minimum needed for normal body function. Athletes typically sit between 6% and 13%, and the “fitness” band is 14 to 17%.
That puts Rez’s stated target at the bottom edge of what the body needs. Health-education pages note that dipping below essential fat can interfere with normal function, and that sustaining very low levels carries risks. Measurement adds another problem: calipers and bioelectrical-impedance scales are error-prone, and no published scan, such as a DEXA result, backing his figure was found. The claim comes from his own bios and captions.
None of this says he is lying. It means “under 5%” is best read as his stated goal and self-description, not a measured fact. Anyone considering copying the approach should talk to a doctor or registered dietitian first, because it is not a target for most people.
Shaun Rez Workout Routine
There is no published, step-by-step Shaun Rez workout. What exists is a set of documented pieces:
| Element | What he has said or shown |
| Weight training | Posts labelled “back day” and chest-press sessions on TikTok. His site says training aims at building new lean muscle rather than only enlarging existing muscle. |
| Cardio | Listed as the first FIVEO ingredient, described as “more effective” rather than longer. No details on type or duration. |
| Martial arts | A competitor page says he comes from a martial-arts background. His own pages don’t detail this. |
| Recovery | Not specified publicly. |
| Programme details | Sets, reps, splits and weekly schedule are not public. They appear to be part of paid coaching. |
Pages that give an exact weekly split or rep scheme for him are guessing. The honest summary is that he trains with weights and cardio, shares gym footage, and sells the specifics through coaching.
Shaun Rez Diet
His diet is better documented than his workout, mostly because he has spoken about it. On The HJR Experiment he called steak the most complete protein, said he avoids fruit because of the sugar, and said he prefers to fill gaps with supplements. His site adds that all of his daily meals are prepared by ICONMEALS, a meal-prep service he says he has used for over five years.
His Facebook bio reads “0 Carb 0 Sugar 0 Cheat,” a stricter claim than his website, which talks about cutting unnecessary carbs and applying carbs and fats deliberately. One competitor page repeats the softer version (“strategic” carbs). Because these descriptions disagree, the exact amount of carbohydrate he eats is unclear.
He has also been linked to fasting, but only indirectly: the podcast episode title mentions it, and he commented on a clip of Rampage Jackson training during a 24-hour fast. Whether Rez fasts himself could not be confirmed.
A near-zero-carb, no-fruit pattern is restrictive. What works for a coach who has spent years on it is not a recommendation, and nothing here is medical or dietary advice.
Shaun Rez Wife and Personal Life
Shaun Rez has no publicly confirmed wife, spouse or partner. Searches under several phrasings turned up no marriage announcement, interview or social post naming one. His content centres on training, menswear, gym humour and his brand.
“Not confirmed” is not the same as “single.” He may simply keep his relationships private, and no article should state either way as fact. If he shares something, this is the section that would change.
Shaun Rez Net Worth
There is only one published estimate: about $3 million, from CelebzFame in 2026. That page gives no calculation, sources or date range, and no second figure from any other outlet was found. A single unsourced number is not enough to treat as established, and net worth estimates generally shift over time.
| Source | Reported net worth | Year |
| CelebzFame | About $3 million | 2026 |
| Any other source | None found | n/a |
For a look at how creator-style estimates like this one are put together, see our guide to Sky Bri’s net worth.
Where His Income Comes From
His own pages point to several income streams, none of which are quantified:
• Coaching: the “Get Coached” route on fiveolife.com.
• Affiliate and discount codes: FATHERSONS menswear (a 25% code), ICONMEALS and The Virtu.
• Social content: YouTube, TikTok, Threads and Instagram.
• Modelling and film work, including Prepare to Die.
Without disclosed earnings, any total is an outside guess. A similar mix of brand deals and content income, with the same lack of confirmed figures, is broken down in our piece on Fat Perez’s net worth.
Shaun Rez Fact-Check: What’s Verified and What Isn’t
Here is the status of each major claim, using one scale: Confirmed (consistent, checkable), Self-reported (his own word, no outside check), Single source (appears in only one place), or Unconfirmed.
| Claim | Status |
| Born February 13, 1982 | Single source |

| Height 6 ft | Self-reported |
| Weight 198 to 205 lbs | Self-reported, conflicting across pages |
| American nationality | Consistent across sources |
| Iranian/Persian heritage | Reported, not confirmed in his own words |
| Under 5% body fat | Self-reported, no published measurement |
| “Natural” or “natty” | Self-declared |
| Cast in Prepare to Die | Listed on IMDbPro |
| HJR Experiment appearance, Feb 15, 2024 | Confirmed (episode listing) |
| Wife or partner | None confirmed |
| Net worth $3 million | Single source, unverified |
| Trained in Kung Fu To’a | Single source |
| Partnership with NB Pure | Single source, not found elsewhere |
Kung Fu To’a: The Martial Art Behind the Name
One competitor page says Shaun Rez grew up training in Kung Fu To’a. That was not found stated by Rez himself, so it stays flagged as reported.
The art itself is real and unusual. Kung Fu To’a is a Persian martial art developed in Iran in the 1960s by Ibrahim Mirzaei. Reference descriptions trace it to Northern and Southern Shaolin kung fu, with influence from other styles, and describe an emphasis on physical and mental health, meditation and yoga-style practice. The name “To’a” comes from Persian, and it has seven main forms. It is far less widely known outside Iran than the Shaolin styles it grew from.
If Rez did train in it, that would fit a Persian-American background, but it remains unconfirmed.
Shaun Rez on Social Media
Several accounts carry his name, so it helps to know which is which:
• Instagram, TikTok and Threads: @shaun_rez, all using the “Shaun FIVEO Rez” name. These carry training clips, gym humour, menswear promotions and shout-outs to Rampage Jackson.
• YouTube: FiveoLifeTV, covering training, diet and lifestyle.
• Brand pages: fiveolife.com and the @fiveolife Instagram account.
• Facebook: at least two pages carry his name, with different bios and weights. If a figure on one page doesn’t match another, that is likely why.
Posts promoting products usually include a discount code, so treat them as partly commercial.
FAQ’s
How old is Shaun Rez?
Shaun Rez is reportedly 44 years old, born on February 13, 1982. That date comes from a single biography site, and he has not confirmed it himself. Pages that still say he is 43 are out of date if the birth year is correct.
How tall is Shaun Rez?
Shaun Rez says he is 6 ft tall, which is about 183 cm. The figure comes from his own social media bios and has not been independently measured.
How much does Shaun Rez weigh?
His own bios give 198 lbs (about 90 kg) on Threads and one Facebook page, and 205 lbs (about 93 kg) on another. One biography site says 185 lbs, which matches none of his own pages. Treat roughly 198 to 205 lbs as his self-reported range.
What is Shaun Rez’s nationality?
Shaun Rez is American. A biography site and his Instagram display name point to Iranian (Persian) heritage, though he has not discussed his family background in any interview found for this article.
Is Shaun Rez married?
No wife, spouse or partner has been publicly confirmed. He keeps his personal life out of his content, so “not confirmed” is the accurate answer rather than “single.”
What does FIVEO mean?
FIVEO refers to his goal of staying below 5% body fat. FIVEO LIFE is the brand and lifestyle he built around it, with coaching, training and nutrition advice. He goes by Mr. FIVEO online.
Is Shaun Rez natural?
Shaun Rez describes himself as “natty,” meaning drug-free, in his social bios. That is a self-declaration, and nothing public independently verifies it, so it should be read as his claim.
What is Shaun Rez’s net worth?
The only published estimate is about $3 million, from CelebzFame in 2026, with no stated method. No second source was found, so the figure is unverified. His income appears to come from coaching, affiliate codes, social media and some screen work.
How does Shaun Rez know Rampage Jackson?
He was introduced as Rampage Jackson’s personal trainer on The HJR Experiment podcast on February 15, 2024. He also appears in the cast of Prepare to Die (2024), which stars Rampage Jackson alongside Michael Madsen and Lorenzo Lamas. No Wikipedia page for Shaun Rez turned up in research for this article.
Conclusion
Shaun Rez is a self-built fitness figure whose public profile rests largely on what he says about himself: 6 ft, roughly 198 to 205 lbs, under 5% body fat, and natural. The age of 44, the $3 million net worth and the Persian martial-arts background each come from a single source, and his weight changes from one of his own pages to the next.
What is well documented is narrower but real: the FIVEO LIFE brand, a listed role in Prepare to Die, and a 2024 podcast appearance alongside Rampage Jackson. Anyone searching for Shaun Rez should treat the confirmed facts as solid and the rest as claims to watch, and this page will be updated if he shares more.
