Is Jeff Cavaliere a.k.a. Athlean-X Natural or on Steroids? Can you build a body like that naturally?

Many of you have been asking for this review. I also wanted to make it months ago but didn’t have Jeff’s body stats. I looked for them everywhere and couldn’t find anything. That’s why I asked on my Facebook page whether somebody has more information on the topic. I was hoping that people following this guy more closely can give me something to work with. I was lucky. One person sent me to a video of the guy entitled:

Triceps Workout – 200 Reps (CAVALIERE VS. CT FLETCHER!) 

As you can expect, the video is basically a brainless pump arm workout performed by Jeff Cavaliere and CT Fletcher.


What else can you expect from Mr. Fletcher a.k.a. Mr. Two Words vocabulary?

Word 1 – motherfucker; Word 2 – motherfuckers;

At about 3:10-315 Cavaliere says that he is about 165 lbs / 75 kg. According to my source on Facebook, he is about 5’7” / 170 cm tall. Thus, his body stats look like this:

Weight: 165 lbs / 75 kg;
Height: 5’7” / 170 cm;
Body fat: deep into the single digits;

If we go to the guide for naturals, which has been spot on many times before, you will see that 5’7” / 170 cm lifters cannot be heavier than 149 lbs / 68 kg in contest condition. As I have said many times already, the guide is for genetic wonders and not many people can reach those stats naturally. In fact, most can’t.

Jeff Cavilere is exceeding the limits by a large margin. However, I doubt he is in contest condition since most people can’t maintain 5% body fat all the time.

If he was to get ready for a bodybuilding show, he would get closer to the numbers presented in the guide. How much weight does he have to lose? Not that much since he is pretty lean already.

Many victims of muscle disinformation have been convinced that people below 200 lbs / 90 kg are natural. That’s simply not true. I encourage anybody under 5’11” to get to 165 lbs while keeping his body fat in the single digits.

Unfortunately, it’s not that easy. I kindly advise the 220 lbs / 100 kg fatsos supposedly breaking the natural records to keep their opinion to themselves. Bros, you are simply fatter than you think.

That being said, nobody can tell for sure whether Jeff is on drugs. I wouldn’t be surprised one bit if he is what I call a shadow pinner, but that’s just about it. I don’t think he is a heavy abuser. It’s really hard to tell with the smaller guys.

Nevertheless,I know for certain that most people will not have similar upper body development (the guy does not show his legs because we all know legs are not marketable) naturally unless they have phenomenal genetics for building muscle.

I don’t care what kind of chest flies you are doing for your middle chest- it’s not going to happen if the gene base isn’t there

Probability of being natty? 3.5 out of 5.

    It’s very unlikely that Jeff Cavaliere is on steroids. He is a physical therapist and strength coach and has a solid understanding of how the body works in relation to weight training, muscle gain and weight loss. If he wasn’t so heavily qualified in the fitness industry and so knowledgeable, then maybe it would be more likely for him to be on the juice as he has a remarkable physique for his age. I have been a fully qualified, working personal trainer for the last 8 years and my stats are very similar to Jeffs’ in terms of I am the same height, same weight but around 8% body fat which i maintain all year round,. And i can assure you i have never once thought about getting on steroids. With correct knowledge and implementation in the gym, it is not hard to achieve great results. Jeff is almost certainly natural

    1. DaveH

      O’Daly, you have no idea what you are talking about. Neither does anybody commenting after you. A lot of naive suckers here.

  2. Anthony

    I also find it VERY HIGHLY 99.58% to believe this ( mind you, I just finished watching your 2 part video on how to determine if someone is juicing or not 45 min. ago).

    But as the dude who 1st posted, I mean I’m 5’9 and I’m at 161 lb. And have never even thought about juicing, I’m even scared of most supplements out there and didn’t subscribe to your channel precisely because u mentioned creatine was “awesome”.. It may be, to me is a little scary since I’ve always tried to be a Baseball player so that kind of through me off a bit. But nah, I don’t agree with it. I’m not 40 or w.e age he may be, but I don’t think that with his expertise and knowledge he’s on anything, specially since in the last video I watched he mentioned he just got back from the baseball owners meeting in Tennessee which tells me he’s still employed by MLB. So nah. Working with MLB I’m pretty sure u can’t be juicing in 2016 lol.

    Good stuff and point on the 2 videos I mentioned though.

    1. Darter

      So just because he is “knowledgeable” he doesn’t take steroids?
      Doesn’t juicing actually require a lot of knowledge?

      Yes, he is knowledgable, yes, his advice is legit, but yes his stats are questionable.

      1. Danny

        Look dude you clearly have no damn clue. I however have done research and the suppluments speak very highly so maybe you ought to do the same before you judge.

  3. B.H.

    In the video posted above, with Jeff standing right next to CT, it can be seen that they are nearly the exact same height (both are wearing what appear to be running shoes). CT Fletcher has been listed at 5’11” from multiple sources, however this may be an overstatement which is not uncommon in bodybuilding, or may have been his height as a power lifter but not now at his age. People typically lose about 1/2″ per decade after the age of 40. At age 56 he could very well be 1-2″ shorter than he was at his prime. At the link posted below, a member over at bodybuildingcom forum had a picture taken with CT, that member says he himself is 5’11” . . . in the picture, if CT was standing up straighter, it doesn’t seem out of the question that he is is 1-2″ shorter than his stated 5’11” . . . which would fit perfectly with his age. This in turn puts Jeff at ~5’9″ not the 5’7″ listed. @ 165 lb with what generally appears to be ~8% bodyfat . . . Jeff has an FFMI of about 24, which while still very good, is not unbelievable at all. This same height/weight ratio seems to line up with the chart posted on this website for attainable.

      People do not lose height that is simply not true. As you age your posture deteriorates and your spine collapses. You do not lose height… With proper care this does not happen. Do not fall into the fallacy of the average.

  4. EJ

    a lot of your posts are missing parts of the text you write. the margin is maybe too narrow and eliminating words which a lot of times make the post difficult to read

  5. TheRicker

    This is exactly how you game the Internet to get your stuff to show up in search results in order to drive traffic to your site. Game another person’s name. Jeff obviously isn’t a fraud his videos are very in depth he has training facilities you can go to where you can meet other people and participate in workouts and programs for the betterment of your health. If you choose to partake in what he actually sells, the products he sells and the programs he sells are actually very good for the individual. Look at his vids. If you don’t choose to purchase what he sells there is a ton of content online for free. Definitely do not agree with your blog. Don’t even want to click your other links.

  6. 6'4"

    He says how important it is to be in shape year round for years or even decades. And indeed for the last few years, judging from his more or less frequent vids, he has had pretty low bodyfat year round. But for how many of us such low bf level is healthy indefinitely? And I’m not talking about few years, but for the rest of your life.
    Not that the answer is that important for me personally, since I’m more into heavy weights than mirrors – especially since no exercise will give me a better looking face 🙂

    1. Skommelling champion

      He’s not in contest condition. People often under estimate body fat levels, I’ve been measured at 8% but I think I’m in the 10-12% range possibly even a little more, I really don’t think he’s in an unhealthy maintenance range, looks like 7-10% most of the time really

  7. Tim K

    Article doesn’t make sense….

    As if a natural person cant be 5’7 170lbs… Look at all the athletes lol
    I for one in high school at 8%bf weighed 185lbs and stand 5’9 After packing on muscle I’m 215lbs.

    You cant go off of a general rule especially when there are so many factors to take into consideration.
    You have to consider bone density and weight organ weight etc… Its too many things that contribute, ethnicity and all.
    Every human is highly unique and nothing follows the so called rule or BMI.

    Dont ever buy into BS articles like this.. Everyone is unique in their own right.
    If you want to make gainz, focus on making gainz, you get discouraged when you start comparing yourself to someone else. Be the best YOU that YOU can be.

    1. Truth Speaker

      Shut the fuck up you ignorant trash.

      Everyone’s organs weigh almost the same.

      Inb4 my Kidneys weigh x3 as your Kidneys.

    2. Phil

      99,999 out of 100,000 people do NOT care about your body competition ego feeding frenzy. Jeff looks absolutely fantastic and does NOT need to lose any bodyfat!

  8. ANALYZE

    The answer to wether he is natty or not is VERY SIMPLE guys!

    Now, let me breack down the analogy in the simplest way possible.

    1/ is it possible to be 165lbs , 5’7” and single digit body fat naturally? Yes
    2/ is it possible to be 165lbs, 5’7” and single digit body fat on the juice ? Fuck Yeah

    now what you need to understand is that CAVALIERE has been working out for a LONNGGG time which means that hes been bulking and cutting for years and years. As you all know, the longer you do something as a human being, you kinda get sick of it at a certain point in your life!

    CAVALIERE has built a business around his knowledge and physique, which means he has to look lean and muscular all year round.

    Now, the right question to ask is:
    ==can he maintain his physique for all this years ( meaning: nutrition, workouts, sleep and supplementation) and run his business at the same time and not forgetting his social and family life?
    The answer is: YES, but its damn HARD.

    ==Can he be using a little something?
    The answer is also YES, this is in case he didnt have much time to do all the things needed due to family problems or work problems or anything of the sort ( you never know what life throws at you certain times)

    CONCLUSION:

    Theres no way anybody can know wether hes using or not !
    the point is that it is possible BOTH WAYS.

    1. Darter

      According to J. Cavaliere, bulking and cutting is a myth.

      The blogger already said he might be natural or an accasional user.

    2. Darter

      What athletes are you referring to?
      Since you used the term “high school” I will asumme you are US American and refer to sports like “American football”.

      American footballers take steroids even at college level.

  9. Todor Arnaudov

    He doesn’t look *that* lean as in the contests, if you mean the freaks at the bodybuilding contests with naked muscles. He might be not so deep in the single-digit %.

    I think that it’s also possible that the data about his height and weight might be slightly wrong.

    1. An inch is too crude+- 2.54 cm (or at least a half)
    2. He might be lighter than the stated pounds (or he should have very thick and hard muscles in order to pack that weight in that body and mass).
    3. Weight can be also +- 1-2 kg, depending in the morning or during the day etc. and whether the one who tells the weight wants to sound as being *heavier* or *ligther*.

    Some comparisons:

    Koray: 171 cm (5.7+1/3), 78 kg, powerbuilder. Participant in two episodes of the “Strenght wars” series.

    https://youtu.be/LYEhr7iJMZw?list=PLgruvnnqP3JQ0uzCMsRyR3YknPUlUjDDM

    To me he appears shorter than Jeff, maybe shorter neck?, limbs, smaller chest or an optical illusion – I don’t know.

    He looks more muscular than Jeff, he is lean. In this video he’s presented as weighting 78 kg, while in an earlier one – 75.

    Lyu Xiaojun: 172 cm, 77 kg. Lean and muscular, very thick, deep back (should be much deeper than Jeff’s) and bigger lats. World record holder in weight-lifting.

    See also weight-lifters in general. There are 165 cm winners in 69 kg (this year European championship, 68 kg), there was also a 175 cm Olympic champion in the same category – Galabin Boevski, he looks too thin. The bronze medalist, Georgi Markov, was 169 cm.

    So you accuse the dude of juicing and discredited his program without trying it?

    I actually OWN his Xero program. The bodyweight only program. And being a recently separated US Marine who had a combat specialty and in pretty solid shape already, not only did I find the super challenging, but after one cycle, I DID get some pretty great results. 1 inch added on each bicep, 1.5 inches on my chest, 2 inches off stomach and waist, 1.5 inches off thighs. I’m definitely a lot stronger than I was when I started and a lot more defined. Bodyfat percentage is down 5% also. And I didn’t even follow his meal plan. I’m going to do another cycle here soon and follow the meal plan…which is super easy. He just gives you references for meals. No strict rules.

    Try the program before you condemn it. There’s a lot of guys in the actual paid portion of the website who have cycled through a program 2-3 times and they DO indeed, look like Jeff. I’m on my way.

    1. George

      Spot on!

      the only people that think Jeff is juicing are the ones who cry because they don’t look like him and to scared to put the effort he does in the gym.

  11. Harold

    Article doesn’t make sense!!!
    Kulbila Samson, a bodybuilder from Ghana,He is forced to train at two homemade gyms,no supplements!!.

  12. Truth Speaker

    You really gave him a 3/5 of being natural? Are you serious?
    Who cares if he’s a physical therapist, knowing every bone, muscle, and human physiological aspect in the body doesn’t change the fact you need steroids to maintain such full muscles while remaining so damn lean.

    I don’t understand why people are so dumb sometimes (not talking about Author, but Jeff’s fans)… There’s no science on earth that replicates steroid physiques because steroids were, is, and always will be the answer.

    No matter how smart you are… You cannot somehow disprove 2+2=4.

  13. Christine K

    Jeff is an ectomorph and to have 5% of body fat it’s absolutly possible. My husband is an ectomorph and he has the same body fat. Everybody can be on steroids but Jeff Cavaliere has an important goal: to stay clean and natural. I clearly doubt that he takes something like steroids and I don’t know why the question is asked. Jeff is an incredible trainer and example, you want the same body? Work hard like him and don’t waste your time trying to find something bad about him

    1. Darter

      If you never ever tried bodybuilding half-seriously dont spew unqualified bs please.

      Jeffs stats are definitely questionable even though he is not a heavy abuser for sure.

  14. jarred

    Who is this writer. I looked for an author but couldn’t find one. Pretty bad of your too scared to show yourself after publishing an article about someone else. But after reading this i can see why you would choose to hide. My email is listed if you are man enough to reply back……I won’t wait up for you.

  15. rottenapple

    Do you realise that Cavaliere is 41 years old?
    As natural you can hardly look that ripped in that age without PED
    He is probably on TRT

  16. Labyrinth13hrs

    So, basically your argument is: “I think the human body is capable of _____ (no scientific resources provided), therefore he is on drugs.”

  17. rottenapple

    Oh, and Cavaliere videos are boring as shit – I was barely push myself to watch more than 2-3 of his YT clips
    Plus he advocate and sells various supplements and similar bs

  18. alfie

    your natural guide is worthless 5’8 176 pounds no steroids havnt even trained over 3 years 8 pourcent fat bmi tested 176 I would be 5 pourcent natural aint got the best genes and I will easy gain another 5 pounds of muscle in no time before you lot need to eat right and train harder or better watches jeffs videos he know his stuff the guy who writes this know nothing

    1. Darter

      The pinching method is not an accurate way of measuring body fat.
      He is definitely not at 4.9%, 4.9% is Ronnie Coleman competition level. He is probably around 8-9%

      I agree that his stats are still questionable

  19. Derek

    You’re honestly dumb if you think he’s on steroids. The dudes been lifting for years what do you expect him to look like some
    scrawny 140lb bitch lmao

  20. McNinja

    Does anyone seriously think Jeff is below 9% bodyfat? I never knew people could so grossly under-estimate body fat percentages. Jeff is 165lbs, ~9% bf, 5’7″ or 5’8″, and can deadlift 495 for reps. He’s put in decades of work and assuming he’s on steroids because your inconsistent ass can’t hit the gym more than twice a month is fucking dumb.

  21. Finfrosk

    Oh COME ON. Jess has none of the signs of juicing. What he does have is a really good youtube-channel with good, smart info.
    Haha, jeez, according to this page everyone with just a tiny bit of muscle HAS to use steroids. And using peoples weight and height to say if they are natty or not is super dumb anyway. Way too many factors play in. Plus, lots of guys lies about their weight, saying they weigh more than they do.

    1. Darter

      What other method than height weight and body fat comparison do you suggest?
      Can we stalk the guy at night and do blood testing?

      The method is decent and he even noted the margin of error

      1. Finfrosk

        A lot of people use steroids, but we still can’t assume everyone does.
        Like I said: finding accurate stats on poeple you don’t measure yourself, is difficult. And like I also said: peoples bodies are different.
        It’s super obvious that stat-comparisons are poor evidence, because a lot of the guys here that are compared and supposed to be uqually big, clearly isn’t even close to be equal. Just on paper. Hence, somewhere there is something wrong. Most likely, the stats aren’t true.
        But you know, whatever.

  22. DaveH

    These comments are so freakin’ ridiculous. One of his pitches is he lists some Mets players he worked with. Don’t you people know that many of the guys he listed were in fact busted for PEDs and/or have been linked to Canadian sports doctor/doping fraud Anthony Galea?

  23. Vance

    I was a physical therapist in the US Army for many years and an exercise physiology guy prior to that. I have worked out in countless gyms around the world. I’ve had the opportunity to observe thousands of natty male and female physiques. I can count on one hand the truly natty muscular marvels in all that. They are out there and Jeff Cavalier strikes me as one. If there were no such thing as steroids people like Jeff C would be winning bodybuilding contests. Yep the average competitive shredded weight would be a “massive” 160-170#. Sorry, some people are just genetically able to maintain a very lean physique while maintaining an abnormal amount of muscle. But they are extremely rare.

    1. DaveH

      He’s not natural. Please. I wouldn’t give a shit except for the fact that he’s conning money out of people based on a lie. That’s why I have a problem with him and guys like him. If he wasn’t trying to sell something, then I wouldn’t give a damn.
