Woaaah! You just condensed an entire kinesiology chapter in 3 minutes. Well done man!
I teach anatomy and this will be a great tool for my students to use as we learn about the muscle fiber types. Great job!
Great to hear!
this stuff is GOLD!
Thanks! Was just aiming for silver.
+PictureFit hahah yea thata so funny
@@bbillyxgood shit in the hood
That is 20% of exercise physiology class in 1996 !
lol true dat
that must've been a really tough course
about 15 looong minutes to cover ALL the material
no way
You sir have just gained a subscriber!
Love your vids~
Woohoo, thanks!
PictureFit gainz 💪
You gained another sub by me
Makes so much sense! I feel more comfortable with lifting weights and sprinting. I like training myType IIx muscle fibers more.
& i love how these videos are short yet informative. I'm taking an anatomy class right now :)
Actually you probably are using your IIa fibers. The body does not want to naturally want to use IIx fibers. It generally doesn't want to be used unless you were under some high physical stress.
@@Perseus07av lifting weights is high stress.
@@lilbrocko yes you are, but it's not an all- in- one Fiber type relationship. The body will pair Type IIa and IIx together and so type IIx does not simple work in isolation.
Still helping people out! Well done for a short, yet extremely informative video
Good job on your videos! keep up your good work and don't give up. I hope your videos gets the popularity they deserve.
Good! Keep doing videos! They are very interesting!
Aurelie Correia Thank you!
Thank you so much for this easy to understand video..you summarized a whole chapter for me in 3 minutes !!
Picture Fit; this was very informative. I highly appreciate your efforts!
Excellent video , I've found this is one of the most overlooked and misunderstood principles for many people looking to gain muscle mass.
I enjoy watching your videos. I am a visual learner and your illustrations are really fun to watch and learn. Appricciate it! Don't stop your vids. Keep 'em coming! lol
+Ruby-J. Mendez Will do, and thanks!

+Tyler Bray Thank you for the support!
This is an excellent video - clear and concise. Well done!
This makes so much more sense to me now than when I read it in the textbook. Thank you!
Best channel on UA-cam. Period.
Thank you this was very helpful. Love how you made the video colorful
keep sharing these awesome stuff ! ❤
This really helped out to understand this course in my personal training class
This has been recommended for 3 weeks now. You think UA-cam would think I DONT WANT TO WATCH THIS. love u picturefit
Another great video! You forgot to mention that Type I fibers can't be changed into Type II fibers.
And since the muscles in our body have more of one type of fibers than the other muscle groups (ex: calves are have more type I fibers than type II) you could make a video explaining that!
un believably educative and informative. THANK YOU
I was having a hard time understanding this whole thing! now I get it! thank you
Hi, nice videos.. keep making more of these kinds :)
I love this! Very creative and super pleasant to follow! Thanks!
+Kelly Starnes You're very welcome =)

excellent video !
very useful, thank you for sharing.
this guy is awesome😃
YEA!
PictureFit Can u explain Thermogenics and CLA benefits? with and with exercise? Thanks..
*I have a question*, lets say you have been doing slow reps since you started or genetically speaking its possible you have more slow twitch fibers by default. You want to hit the type 2 a and x fibers with fast reps but they are less conditioned as a result of your training and/or genetics.
If my understanding is correct then your ability to lift more weight is more dependent on your slow twitch muscles as they make up an unusually large amount of your power out put and thus you have a hard time lifting heavier weights fast in order to hit the other types. Like I said I'm not sure if the assumption of mine is correct but if this is why I have a hard time doing fast reps at heavy weights can I hit the type 2 muscles fibers better if I take the weight down bunch more notches and lift it faster? If not how can I get fix this? Perhaps its in my head, I just want the most I can get.
Robert Dicke lift moderately heavy with compound lifts short recoveries your tempo should not be fast but at a constant fluid motion while performing the exercise 8-12 reps 60-80% of how much you can lift is good start then try and go for 12-15 reps after a couple of weeks. Learn sprinting drills and techniques start incorporating them into your cardio routine hope this helps
Robert Dicke and one more thing, if you cannot perform compound lifts with good form you may suffer muscle imbalances and still may need a trainer to aide in instructing some corrective exercises not to mention foam rolling, stretching and knowing how and when to start and stop your deloads
Well done! Really great and easy to understand . Keep it going.
+TheGL1005 Thank you and will do! If you have any other video suggestions, please feel free to share!
Awesome video!
I was always a sprinter as far back as I could remember, and sucked at long distance running. Now as an adult I took a DNA ancestry test, and among other things it told me, just as I suspected, that I'm fast-twitch dominant.
Me too, I have 2 copies of the fast twitch gene, but it hasn't helped me run fast, and if I were to choose one type of running that I think I'm best at I would've picked long distance. However, if I do exert maximum force my muscles do tend to fatigue quicker than most other people's. I don't know what to believe TBH.
Woahh I didn't know you can get that tested.
Ah, could that explain why I've always been so bad at running?
Sounds more like an excuse
Jackal I bet you’re the type of guy to kiss his dad on the lips 😂
Probably the most easiest way for me learn about this. Thank you and I hope you make more videos
+J.H.Thomas Won More videos coming soon =) Thank you for watching! Please share any other video topics you would like to see.
covered everything I needed to know for anatomy.. please make more videos!!
Hah, I'll try!
your video is really helpful. Very easy to understand! Thank you so much
My pleasure!
good job fam, your helping me understand my anatomy classes a bit more
+Noel Gonzalez Keep it up!

Thank you very much ! I love the presentation !
Great review on muscle fibers
It's very helpful to me! When i saw this movie, i understand about muscle fiber! Thank you very much!!
You really deserve more recognition for your effort..
Thanks!
I freaken love this guys videos!
This is very helpful and deficial
Thank you. "You explained so well and easy to understand..
your channel is really informative and useful,thanks a lot.

Good shit man..
i love you!!
thanks for helping me understand :D
you, my sir, are a god send
Great explanation.
wow. very detailed yet simply explained. thanks
My pleasure!
this is amazing thanks man
great videos! great drawings!
you are awesome man!
Regarding the size principle: are the muscle fiber types recruited according to load (force) or to effort? If you hold a light weight in an isometric contraction, it gets harder and harder as time goes on-your effort increases even though the load stays the same. As you approach failure you end up recruiting all muscle fiber types. You drop the weight once all fibers are fatigued.
effort matters. not the external weight
Both matter
Great video :D
Your channel is pure gold man; you're a legend!
Can you please make a video about how exactly hypertrophy takes place? What exactly happens in the muscle while working out which makes it grow bigger?
It's a lot of science-y stuff. Lots of cell activation. Things like proliferation and differentiation take place. Nuclei are added. etc etc. I would love to but I wouldn't know when I will have the time to break down a video like this.
PictureFit Fair enough man I appreciate it anyway! If you ever do find the time I'm sure it would be an awesome video; even if you only go over the concepts of muscle damage, mechanical tension and metabolic stress via exercise. Thanks anyway and keep the great videos coming!
A fitness version asapscienc. Best channel for exercising scientifically
Thank you, thank you, thank you!!
brief and easy to understand.
awsome video
Very useful thank you
THANK YOU for this !!!!
You're very welcome

I'm type llx, thank you for that info...priceless,!!
I wish you had more videos on anatomy and physiology
Type II x all the way
good channel keep going
+slimboy808 Thank you!
I loved this video
Thanks!
your welcome! :)
Thank you very very much
Subbed my freind good stuff!
Thanks!
pls make a video on which is better to build leg miscles, squat or sprints.. thx
You are so smart!😀
thank you so much
u da best, thanks
Seriously, each video is better than the one before. Great work! So much knowledge! But how do you know all this? Are you a certified trainer? A Well-informed enthusiast? A Teacher?
+PbVeritas A little bit of everything ;)
His videos are intricately detailed and really help, unlike other mediocre videos.
this is so brilliant! thank you so much i love the pics. Can we download the 3 pictures from anywhere?
+Liza Coyle Sorry, we do not have pictures of the fiber drawings uploaded. Best approach is to screenshot the video and save it for your own use! Hope this helps!
Wonderful video
+Ang Jo Thank you! Any other topics you might be interested in seeing in a future video?
Picture Fit You're quite welcome! And sure. Maybe you can do one about "top fitness questions", or anything else about movements in the body. Or anything you want! Whatever you choose, I'll be sure to check out. I subbed! And thanks for responding!
We are looking into utilizing "top" lists in the very near future. Thanks for the input as always and thank you for subscribing! Hope to hear more great ideas from you!
The more I learn about the human body the more I marvel about the astuteness and brilliance of the designer behind it, whether it’s God or Nature!
Wait so every skeletal muscle has some of each fiber type in it? What does the distribution look like?
So my bicep would have all three but more of the type II-x????
about a third each, thats why you should train heavy explosive and light controlled to maximise gainzzz
thank you soo much
I feel like I got the understanding of this. And I would have to say my type are very equal. due to I am able to move pretty fast and my endurance is on par with it.
Type 2a. Thx for posting. :)
type2x
thankyou for information :)
this is literally how i understand the difference between the fiber types
This helped me so much! Thank you!
+Benny Stimson You're very welcome! Please feel free to share any other topics you are interested in seeing a video about!
Really helpful for me tnqu
Hey can you do a video on bands or isometrics? That’d be cool.
I play a lot of basketball and row at the gym so I think more Type II muscles since I only do short 1 minute bursts of rowing and a lot of short burst of movement for basketball
Since my purpose is to have stamina & strength endurance, I'm training for type I and type IIa mostly, thru exercises such as long distance running 🏃🏻 and sometimes hiking. Now I'm thinking that somehow I have to train for type IIx as well, so that aesthetically, I'd look better while having adequate strength as well
This Channel reminds me of asap science.
Its like

Holy s*** you're so awesome I wish I wasn't so poor so I can donate to you or something. I appreciate all the videos you put up
WELL DONE(Y)
