Mike O’Hearn – Natural or NOT?

Michael (Mike) O’Hearn is a popular American bodybuilder, actor, powerlifter and fitness model. He is famous for his aesthetic physique and “classic look”. Mike O’Hearn claims that he is a natural bodybuilder. However, there is serious evidence saying otherwise.

1. Mike O’Hearn is bigger than former IFBB pros.

According to Mike’s page on bodybuilding.com he has the following body stats:

In comparison, Arnold Schwarzenegger (7 times Mr.Olympia) had the following body stats in his prime:

6′ 2″ (187.5cm)


235 lbs (106.5kg)



Body fat levels:


To summarize: Mike O’Hearn is an inch taller than Arnold Schwarzenegger. He is also 12lbs heavier and a little leaner. The LBM* of the two athletes is as follows:

*LBM – the percentage of total body mass that is lean (muscle, bones, water, organs..etc.). LBM = total mass minus body fat.

Mike O’Hearn – 237lbs/107kg (96% of 245lbs);

Arnold Schwarzenegger – 223/102kg (95% of 235lbs);

Mike O’Hearn has 14lbs/6kg of LBM on Arnold Schwarzenegger. Turn off the TV and think! How in the world is a natural bodybuilder bigger than one of the greatest bodybuilders ever?

Note: When Arnold Schwarzenegger competed steroids were legal. The doctors were writing prescriptions easily. The gyms were full of dealers and most competitors were open about their use.

2.Another factor to consider is Mike O’Hearn’s strength. He is not only a bodybuilder and a fitness model but also a powerlifter. His best lifts are:

815 lbs/370 kg squat – about 3.3 times personal bodyweight;
505 lbs /230kg bench press – about 2 times personal bodyweight;
760 lbs /345 kg deadlift – about 3 times personal bodyweight;

Similar lifts are almost impossible for a natural and are unseen in TRULY tested powerlifting meets.

3.Mike O’Hearn looks like he was composed in PhotoShop. This alone is a clear indication of what’s going on. The fullness and the quality of the muscle mass are speaking the truth. Natural bodybuilders rarely, if ever, look like that. In the end of the day the decision is your.

{you decide}


Q: Why would Mike O’Hearn lie about being a natural bodybuilder?

A:It’s simple – to protect his contracts with supplement companies and keep on making money from photo shoots. Also, ridiculous claims tend to gain people’s attention. More on why bodybuilders deny steroid usage and addiction can be found here.

Q:Can I build a physique like Mike O’Hearn’s naturally?

A:Nature says it’s impossible.

    This article is so inaccurate. Arnold’s competition weight was 265 pounds not 235… Do your homework.

    1. kw

      Do your homework…that was his off season weight:
      Name: Arnold Alois Schwarzenegger
      Website: http://www.schwarzenegger.com
      Location: Los Angeles, CA
      Born: July 30, 1947
      Birthplace: Graz, Austria
      Height: 6’2″
      Off-Season Weight: Around 260 lbs.
      Competition Weight: Around 235 lbs.
      Arms: 22″
      Chest: 57″
      Waist: 34″
      Thighs: 28.5″
      Calves: 20″
      Favorite Exercise: Bent-Over Rows

        I think it is more likely that he is lying about his stats. There is NO WAY his arms are only one inch smaller than Arnold’s. It looks more like three or four inches difference to me. That would put him at about 18 inch arms, which is still a little outside the “natural” limit. He is tall though, so it could be possible. I doubt it though. He wouldn’t be able to keep all of that mass below 8% body fat or so.

        1. Jun

          That picture is old and if you look at mikes arms now and his size, those stats are more believable…mike is definitely larger than he is in that pic

    2. trandana

      Mike was also taller than Arnold, which gives a big advantage. People underestimate how much an extra inch will add in weight to your body.

  2. AC

    Natural or not? Any one who competes is using. PRO level or not. It’s a fact. Most people understand this.

    As for the “Mr Natural Universe”..I’m sure there’s ways around it knowing when they are going to be tested. And for what substances. Cheaters always find ways.

  3. John

    True. Arnolds arms and chest dimension is much bigger tan Mike. But Mike being on better drugs today ‘s much more ripped in terms of body fat. But at 235 vs 247 and per pound was way bigger.

  4. Breezy

    Family genetics plays a role in body composition. What do his dad and brothers look like? My buddy Dan is a big dude like his Dad and Gramps. He kills us in the gym. When he eats right he gets pretty lean too. We don’t get all jealous over it and talk about whether he’s secretly juicing. You guy’s need to get a life and stop caring so much. If you want to get big then kill the weights and eat right and get out from behind the computer. Typing bullshit about others doesn’t get you in shape.

    1. jai

      What an idiot u can be?? I mean people, simpletons like you at everywhere… instead bashing a liar who profits off people and their innocence ( mike ), u call people who expose him as jealous..
      U are pathetic…

    The crazy thing is how people dismiss everything to gear. Cheddar or not, the results are impressive. Dude raw lifts high weights most never get to, on or off juice. Check YouTube when he squatted 315 42 times for his 42nd birthday. Keeps a 29″ inch waist while most pros show bloat. Natty or not, it takes dedication and hard ass work to get there. I’d rather know his secret combination and would show no shade if some supplements are mixed in.

    O hearn has tested negative repeatedly but you really can never tell because he is not tested every single day. People do need to recognize genetics play a crucial role. People arent that diff than dogs. Some of us are born with t-cup poodle genes and others of us are born with genes of Cane Corso. I hope im somewhere in between. I do think most nfl athletes are natural and some are not much smaller than Mike O Hearn. If they had time to only lift and diet could be as big. O hearn looks nothing like the OLYMPIA pros. Roelly is 5,6 285 he is juicing HARD

  7. Paul Jacoby

    Genetics do play a role. Im sure he takes everything legal. Also people are forgetting hes been working out for longer than some of you guys have been alive. There are guys in the NFL who are natural just a bit smaller. Imagine if they had more time to spend in the gym.

  8. Dj

    Jealousy is a bitch when it comes to this site. There are very few of us on here who still appreciate people’s work ethics and physiques regardless of what they are doing. And it’s funny how I read that the steroids now are better. Hell no they aren’t we have all kinds of fake stuff now and after everything being banned and company’s coming out with prohormones and things like that. They had it made back in the day. I would like this site a lot more if they didn’t dismiss everything any of these people achieve.

  9. Joe

    O’Hearn is 100% NOT natural. Nobody can be 240+ lbs of muscle at 4% (OMG) without juice. The MF makes money out of young believers. That is what he does for a living, for pete’s sakes! He lies, lies, lies. There are many ways to beat the testing. Haven’t you heard of Lance Armstrong and ALL his team mates?
    These guys are on it for the money, is their profession.
    Most supplements out there are crap, but then some like creatine and whey protein help, if not a lot, some.
    Almost anybody can get 10 or 20 pounds heavier through some years of training. But to put 20 pounds and stayed ‘ripped’ at that wait DOES not happen. Muscles turn flat, you lose part of it. Steroids work, no doubt about it, but who wants or needs to be that big and nicely ripped anyway if by doing so you risk your health and waste your money. What for? Are you going to make money from showing your body? O’Hearn is and he will lie forever to keep business going.

  10. Chris

    I honestly find the Mike O’Hearn story quite sad. He’s achieved an incredible physique and pioneered modern aesthetics. He’s achieved a vast amount in the industry and we should all be looking up to him – natty or not – in awe, and looking to his methods for our own personal growth. For years his physique has been one of the greatest on the planet. But because of his incessant refusal to admit what we ALL know, every lifter on earth sits here bashing him for being a hypocrite. He’s done a thousand good things for the industry but sticks by 1 big bad lie, and that ruined him in the eyes of his peers. But he’d never have had the success and endorsements he’s had if he admitted, so… it continues.
