People who are usually put on the spot will typically choose an answer that isnt obvious due to nerves from overthinking the prompt. You probs do it to. Like when you do a math problem on a test and you get the answer too fast so you start doubting. Nothing to do w being slow
@@johnmurphy3242No, that literally has everything to do with being slow. You try to think, you can't figure it out, so you go with a gut answer, and you doubt yourself because you realized the answer you got was a gut reaction rather than being able to quickly actually think it out. Not everyone who does that is slow all the time, but as you said here his brain literally froze from being so slow 😂
There's also been a study that found that there's actually 7 heads to the deltoid, pretty interesting stuff. Edit: Apparently the individual "7" heads aren't heads of the deltoid, but instead individual segments.
@@Equinox8 there is a possibility actually that there is 15 deltoids in your quadriceps because ur triceps only use 3 heads so scientists now have been expiriencing in 500 gyms around the world to see if segments take it to the next level head giving.
@@ditoo2002yeah it’s quite a fascinating concept, and you’re correct! (This is long, sorry, but hopefully you find it interesting since much of this content is educational anyway!) But it’s not quite as simple as “there’s a 5th head”. There’s a concept called anatomic variation, where individuals develop slightly different based on genetics, environment, and muscular demands based on regional and cultural expression (like a snow fox vs an orange fox, kinda). In much of the literature about these variated muscle heads, there’s an established normal variant, with an understanding that other expressions exist and may alter treatments or even make someone more susceptible to certain conditions. Another great example is the piriformis muscle, which has 6 known variants in how it looks! Studies show that somewhere between 30-40ish% percent of people have a 5th head, usually called the “vastus tensor”, with normal presentation being the 4 major heads in the rest of people. The bicep has about a 10% chance to have 3 heads, and mostly it’s in females strangely enough.
@@adamcarman5330 thank you for the knowledge, that's actually right up my ally. I study cybersecurity, but I for some reason are fascinated with biology, more specifically genetics and how it works. I never knew that as of right now, some of us could have more muscles than others based on demand on the body and whatnot. Very cool.
extension of a muscle is not a thing in anatomy/physiology. muscles contract, relax, or stretch. extension and flexion refers to bending joints. what he means by "leg extension" is actually knee extension because the knee joint is opening. I'm sure the machine probably says "leg extension" on the info plaque so in that sense it's technically correct, but it's still anatomically incorrect.
Meh, nomenclature really often involves some old "insight" or false assumptions, ultimately turning the "real deal" into a misnomer. Just think about the atom, to most of us, the thing we literally called unsplittable turned out to be most famous for being exactly the opposite. And I mean, why wouldn't you metagame the thing, too? He asked Jeff to give him a harder one, and going from tri- to quad- isn't exactly that... if anyone were to assume this is a trick question, fair game.
It only makes sense if they understand the question to be referring to the protein sold at the gym. Because as you point out it varies based on brand. Different brands have different concentrations and different scoop sizes
My husband is on his weight loss journey and he is currently 280lbs. His legs always looked like he was a lifter. Well, he was always lifting his top half😂
So truee. I dont even train my legs with squats, yet they are full of muscle. I'm a big guy (I weigh 215 pounds) and when i run i both train legs and lose fat. If you weigh a lot, then just run. If you do squats wrong, you might injure your back.
_How many heads are in the QUADriceps?_ That’s the academia side of him coming out and doing that emphasis in the quad part 😂 like “come buddy, I know you know this one, try again”
ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0fEtknfojpE.htmlsi=GJRPIF6_qFcWpDE- Not that new but definitely relatively new, I'd never heard of it either
The bots are getting worse on RU-vid. I noticed accounts popping up on Dr. Mike Israeltels channel, and now they're here. Does anyone know if RU-vid will fix this? There are young kids in these comments who might see these bots.
Lol do you really think RU-vid will fix this? They are too busy cracking down on adblockers and deleting random comments instead of dealing with t*0t bots.
Quad's have 5. "The tensor vastus intermedius (TVI) is a newly discovered muscle located in the anterolateral thigh (ALT) and is considered the fifth component of the quadriceps femoris muscle." Gotta rename them the Quinticeps
Always trying to adapt ur wisdom words to my calisthenics You should do a video talking about nice ways to target muscles without machines, dumbells, or so and so, just bodyweight! 🙏🙏 Keep the grind guys💪🏾💪🏾🔥
People say the bicep is just two muscles but there's a huge variation there. Some people have MORE bicep heads, something like 10% of people have 1 or even more bicep heads. Not to mention that the biceps also have overlap with the brachialis and delts. The brachialis is often lumped in with the biceps for gym purposes and the biceps also have a small overlap with the delts in both purpose and real estate.
Bicep - because it has one muscle Tricep - because it has three heads Quadriceps - because there are four muscles in our quads I learned a lot, thanks 😅
What do you mean with wrist and especially press? I think by "wrist" you mean forearm, but what is press? Also grouping legs and shoulders is a bit weird. My 4-way split is: 1) Chest, Shoulders 2) Back 3) Arms (Biceps, Triceps and maybe 1 isolated forearm exercise) 4) Legs, Abs
Massive nerd moment from an anatomy major but, the quadriceps group consists of 4 muscles with 5 heads. One of the quad muscles - the rectus femoris actually has 2 heads (straight head and reflected head)🫡
This does go too show that Arnold did put in a ton of effort too get into character for some of the roles he played and his dedication in transcending body building
Jeff quick question for you real quick, on your last push pull legs series you gave us the exercises with the number of reps and sets, but you forgot to specify if we should keep the weight the same every set or increase it a little every time.
