Marijuana And Bodybuilding: Does Weed Affect Muscle Growth?

Hey, what’s going on guys? Sean Nalewanyj
here,, and enough people have asked me about it.
So, here it is marijuana and bodybuilding. Does smoking pot affect muscle growth or fat
loss? Now, two things first before I continue. Number one; this video is specifically addressing
the effects of marijuana consumption on building muscle or burning fat. So, is there any direct
connection between the two? Whatever other negative or positive effects that it might
have on someone’s health, that’s not the topic here. That’s a massive subject. And
you can research on your own to weigh out the benefits and drawbacks for yourself. And
secondly, this is a completely unbiased video where I’m just presenting the facts that
are available as I see them. I’m not advocating smoking pot or not smoking pot. I could care
less whether you do it or not. It’s totally your choice. So, I’m going to attempt — keyword
attempt to keep this concise. That usually doesn’t happen, but let’s try. So, the
typical response that you’ll usually get when it comes to the issue of marijuana and
bodybuilding is usually something along the lines of, you know, if you smoke weed, then,
you’ll just end up lazy and unmotivated. You’ll skip workouts, you won’t train
intensely, you’ll get the munchies and over eat, you won’t be able to focus, so on and
so forth. And I personally think that’s just kind of a lazy almost cliché answer
at this point, because it doesn’t say anything at all about the dosage and the frequency
involved, individual differences that might come into play or what the actual research
says on the issue. So when it comes to weed and bodybuilding, the main issues of concern
are basically hormonal. So, the way that it affects levels of testosterone, growth hormone
and estrogen. And I have reviewed the research that is available. And as far as I can tell,
there are no studies, currently, that show that moderate marijuana use has a significant
long-term effect on those hormones that would cause you to gain muscle or burn fat less
effectively. At least not to a degree that would be noticeable. So, with testosterone,
you basically see small short-term decreases after smoking, which then go back to baseline
fairly quickly afterwards. And even when test levels do drop, they still stay within the
normal range. Heavy use might be a different story. But again, the studies are still mixed.
Some show lower levels, but again, still within the normal range. And other show no real difference
at all. And again, remember that the simple act of increasing or decreasing testosterone
levels that really doesn’t say anything on its own, because in terms of it affecting
muscle growth, those levels have to be raised or lowered, and to a significant enough degree
and then sustained over prolonged period in order for it to really matter. So, after testosterone,
you have growth hormone. In this area, you only see decreases when very large doses of
pure THC are given. And even then the decrease is pretty minor and it’s temporary. And
one study even showed an increase in growth hormone. And when it comes to estrogen, again,
mixed results. I’m not going to go into all the details here. Some in-vitro research.
So, basically test tube studies that were done on rat cells. Those have shown an estrogen
lowering effect. But then the research that was done on live rats, couldn’t replicate
it. And research — some research has shown a negative effect, but only at very high doses.
And I will provide some references in the description box below, if you do want to check
them out. So, based on the studies that I’ve seen as well as just general anecdotal evidence,
I personally can’t see any good reason to tell you that moderate use of marijuana would
slow down your rate of muscle growth or a fat loss. And even if it did, it probably
would be very minor and you probably wouldn’t even notice it. Now, that obviously assumes
that your overall training and your diet remain exactly the same. If marijuana use causes
behavioral changes, which is then carry over to your bodybuilding program, that’s obviously
a different story. For example, if it causes you to significantly over eat on a consistent
basis, because of increases in appetite, then of course, that’s going to have consequences
when it comes to fat gain. Or if you consume it close to your training sessions, and you
find that it lowers your workout quality or either you end up skipping all together, obviously,
that’s not a good thing either. But again, those are behavioral changes that are within
your control. And they aren’t a direct result of marijuana itself, physically lowering your
body’s muscle building or fat burning capability. Now, what about frequent heavy use? My stance
there is just that I don’t see enough information for me to comfortably say that that’s not
going to have any effect. It very well might not have an effect, but I just don’t know
for sure. So, if you’re someone who is using it daily or multiple times a week, again,
it might be totally fine. I don’t know. But I would say to just take the facts that
I’ve given into consideration. Do some research on your own. And then, weigh it off against
how it affects you personally, and what you’re fitness goals are and then just decide for
yourself. As for moderate use, so maybe once a week or less, again, I’m not advocating
that you smoke or don’t smoke pot, but from a pure bodybuilding perspective, I really
can’t see it being a problem. It’s possible that there are other health reasons why you
shouldn’t smoke it. But that’s beyond the scope of this video, and it’s something
that you’ll just have to research and decide for yourself. So, thanks for watching guys.
I hope that was an unbiased evidence-based answer to the question. I know that some people
do get flustered by this topic. But it’s 2015, alcohol is a drug, the stuff in your
pre-workout is a drug. There are a lot more serious things to worry about in my opinion,
than if someone smokes a bit of pot here and there, just my opinion. Feel free to share

  1. Hey guys – I smoke weed

  2. It does not affect muscle growth, at least not negativly, or else they would of screamed that from the rooftops a long while ago already.

  3. Helps me with lazer focus

  4. why didnt he drop any references?or link? 🙁

  5. Didn't waste a second of my time, a well produced non-biase factual, video with backed up research that cleared everything up for me. Thank you!

  6. I smoke every day and work out when I can.

  7. Wiz Khalifa has joined the group chat…

  8. Im not sure but thc pretty much doesnt change anything on my muscle growth. Anyways, im a beginner, so muscles are building fast anyways. (I usually take a big bong hit before i work out. I can focus better but i have ADHD so that's obvious)

  9. I eat cannabis before my workouts and training MMA!!
    It’s unbelievable how it helps you focus and gives you a lift of energy !
    If you get sluggish using cannabis it’s because u use too much!!
    So try using less!
    But the stimulation from cannabis will give u a workout like you never had before!
    Listen to your favorite music and get your jam on !!!!!!!

  10. Eat or vape
    Smoke decreases oxygen levels
    Just extra tip from someone that smokes it and wants to change method
    PLUS CBD combined is better than THC alone!

  11. Trust me, as a nationaly ranked bodybuilder, the use of marijuana is common and if anything is beneficial to gaining muscle, via lowered stress and cortisol levels, improved sleep and beneficial appetite increasing benefits. The belief that it makes you lazy and eating uncontrollable eating is misguided. Bodybuilding is a discipline that if something like weed is going to make you skip workouts and eat everything in sight… Well, in my opinion you never had the self discipline to make it in bodybuilding to begin with.

  12. Sativa plus caffeine is where it's at!! Rogan and the Diaz brothers use it to increase intensity.

  13. Everyone's in here is a pot head

  14. Please good sir,
    Can you re-articulate/break down
    "here and there"????

  15. So if it raises the quality of my workout due to preventing me from being nauseous I suppose it’s a performance enhancing drug for me? :p

  16. He is cute

  17. For anyone who lifts stoned is stupid af. It's fun tho

  18. I smoke only before gym. About 2-3 times a week. Great time and makes work out worthwhile.

  19. I vape around .05-.1g first thing in the mornings while hydrating and work out in my room before I have breakfast, everyday. I also sometimes get high again afterwards and cycle to the local steam room / sauna. Honest reflections.

    My stretches are of better quality while high. A sober stretch before I workout, is usually fairly rigid and half arsed. A stoned stretch before I workout is flexible, deeper and I get end up taking a lot more time out to do them.

    As far as results are concerned, it definitely screws up performance both ways. Sometimes my focus is extreme, to the point of near disassociation as I somehow "find" the strength to do extra reps. Sometimes it can add upwards of 5 onto my expected peak of an exercise, if I am really in that zone. Other times, I am 2-3 reps lower than I what I expect, because fatigue sets in much earlier, the muscles seem to just feel heavier faster.

    As far as the psychological effects are concerned, I feel like I get a more accomplished workout in. My mood is noticeably better afterwards, especially on mornings where I could not be arsed to work out normally. If I were to stay sober, chances are, the workout is less likely to get completed. I think the effects it has on the mind need to be controlled and directed, otherwise it will wreak havoc on your workout. There used to be times I would only do 2 out of my 5 excercises and call it a day because I was making excuses and giving myself a pass because I was high and tired. I do not do that anymore though.

    My most important thing to say is that it helps a lot with eating afterwards. Not everybody has the habit of eating in the morning, for me, weed has helped me to stuff a lot more down my face. I'm not some cheech & chong inspired idiot, it's not junk food and I'm not lazy. I eat relatively good and healthy food, most mornings I can expect to eat 4 eggs, bacon, sausages and toast. Or perhaps I make salmon, spinach and potato wedges. Eating clean is just as rewarding, if not moreso, whilst stoned imo.

    It's a shame that stoner stereotypes instill uninspired, lazy, effortless hedonistic consumption and habits in people who could be capable of so much more.

  20. Hits the bong

  21. I do smoke basically everyday and I always lift too, I eat well, and sleep well and I've seen pretty good results even tho I can call myself a heavy smoker, I mean I have kept doing things well, I wonder what would it had happen if I would do all my shit well and not smoke weed, idk if I would have better results but I honestly have not get stucked and I'm pretty happy right now with my results (I'm not a beginner in the gym but I'm natural)

  22. Im so confused right now should i smoke right now before sleep and hit the gym tomorrow.. im a powerlifter im not sure if it will decrease my performance or not, i need to break my pr on deadlift.

  23. It definitely effects fat loss due to the munchies. And thc has been shown to lower testosterone. But I'm still pretty shredded.

  24. nice video

  25. well i do smoke weed daily ..
