What makes muscles grow? - Jeffrey Siegel

View full lesson: ed.ted.com/lessons/what-makes...
We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and strong as possible.
Lesson by Jeffrey Siegel, animation by Brett Underhill.

[@yudoball]

Takes 2h and 50$ per h

[@hrag03]

I really liked this video about how our muscles grow and what makes them. A few years ago I used to exercise a lot, and see no much change in my muscles mass and strength. However, I started searching up the internet for the reason, and I found reasons, which were also mentioned in this video, that I also have to eat food containing protein, which will allow my muscles to become stronger and bigger. Also, I didn't sleep enough to rest my muscles, which also resulted in not making them grow. In my opinion, if anyone wants to start gaining muscles and become stronger, they have to sleep well, eat well, and finally, workout constantly. To be more specific, not to skip any training day so the muscles will learn the pattern and continue growing and becoming stronger.

In the fall of my freshman year of high school, I dislocated my right kneecap. I learned that I am hypermobile and that my ligaments are loose and that my muscles hold me together. So loose in fact, that I cannot get a full body readjustment at the chiropractor. It took over a year of physical therapy, but now in the spring of my sophomore year of high school, I can run, jump, and do everything I could do before the accident. I'm taking a strength and conditioning class and I feel my body is stronger than ever before. I also have to stretch often and can't stay still for too long because my limbs will seize up, and my joints will make a sharp crack sound (which can be painful at times). The stretching is a great warm up, and it helps me relax.

When I started working out, my two main mistakes were lack of sleep and not eating enough (not being in a caloric surplus). I always thought I was eating enough and was disappointed because my weight stagnated. Then I got my first diet plan created (I think it was from nextleveldiet iirc). I realised that my previous food intake was way below my needs, although I thought I'm good. At the beginning it was hard to eat 3500 kcal in a day, but I got used to it. I started noticing real gains and it felt amazing. I wish I'd understood the importance of diet earlier.

I had the same problem when i was in my early twenties. I would always workout plenty during the week but i would just stay lean and not bulk up. Finally i just did an experiment and started eating like crazy. Two breakfasts. Lunch. Afternoon snack. Dinner. Wake up at 2 am and eat greek yogurt with granola and then pass back out. Needless to say in one year i gained about 35 to 40 pounds. I went from 140 to 180. And being only 5’ 7” with small bones, I achieved a pretty great all natural physique. And now the gym is all about maintaining that muscle and for mental health.

RIP muscles

[@PinkeySuavo]

Actually once I have thought about such thing. What if we just did some kind of operations in order to make mini-cuts in our muscles? Would they just grow stronger? Wouldn't it be weird that muscles get stronger and bigger without any exercises? I just wonder if it's possible.

[@JenAiMarreDeSaucisse]

@@PinkeySuavo seems complicated. Some people have big muscles and yet struggle to use them and activate them properly because they’re not used to the effort. For example, some guy with relatively thin arms but has been doing curls for 2 years might do as good or better than someone with muscles twice as big but without doing any curls whatsoever. It’s called mind-muscle connection and the more sport you do, the better it gets and the faster you learn new movements and the better your control of your body is.

[@df0rdeath58]

@@PinkeySuavo Possibly. But I think it would be more of inducing strain on muscles rather than operations, kind of like a message except it causes muscles to tear and work without you putting in the effort. If so then there is physiotherapy sessions that is done for people with disabilities but they are not as effective as working out yourself. I guess maybe in the future we could maintain perfect bodies without work, but right now I don’t see any other option except putting in the work.

“Meaningful growth requires challenge and stress.” That’s a great quote.

[@VelhaGuardaTricolor]

No it isn't because omits a lot of the sound information it presented during the video. Healthy challenge and a proper amount of stress, as long as you consider TWO other ginormous factors, 1. Enough FUEL (proper nutrition) 2. Enough REST (Sleeping 8 hours without a break) People love to focus on the NO PAIN NO GAIN... Pain is easy, but without the other two it is pointless. So if your BOSS give you that line: "Meaningful growth requires challenge and stress.” Tell him... As long as I don't get overworked and underpaid.

Thanks Will how much time you spend on working on your muscles daily affect yours results? And also does this apply to training your muscles to do an activities such as soccer tricks? example: Will working on my arms with arm exercises for 10 minutes give me x2 the effects/results of doing it for 5 minutes?

[@zagros24]

+Arash Lawi bro I don't know what's your goal is or what you want to achieve? but to give you a general info about bodybuilding is that the most important rule is the diet! you won't go far if you don't have proper diet! There are tons of videos and articles on internet made by experts regarding your question. I can't tell you what to do since I'm not an expert nor I know anything about your physiology!

[@comradevaldimir7882]

Aryan Zagros Alright thanks I will do that. I was talking about getting fit for soccer too.

[@zagros24]

+Arash Lawi np bro. I dunno what training is best for football but I know bodybuilding is definitely not a good choice because in sports like football you need to be agile thus bodybuilding make you heavy and stiff which slow you down.

[@comradevaldimir7882]

Felipe Costa I could change my comment to some outrageously repulsive idea. People will see my upvotes and think "is this guy right somehow right"? This in turn will lead to changes in attitudes and the way people think. Revolutionary stupidity will follow as defenders of my claims burn down buildings to prove me right.

if muscle gets stronger when it rips, what if you took a microscopic knife and cut your muscle or use nano bots to cut your muscle, would it give you bigger muscle without exercise?

[@zacharyadler4071]

Wow never thought of that.

[@jonlanier_]

Your muscles won't learn to take on a load. Your muscles will never learn to fire properly (electricity is what fires the muscle fibers so they can take on bigger loads).

[@DarkShadeZ13]

@Mc Peyn not really, kind of right but people in comas have their muscles exercised for them they dont know its happening but the physiology of the body works the same because its pretty much automated. and actual mental stress is not good for muscle growth because of hormone release and lack of rest that comes with mental stress. what first name said would work as long as you couple the "nanobots" with some inflammatory drugs to increase blood flow to the muscle.

[@edheldude]

This video didn't point out clearly enough that strength gains and hypertrophy aren't the same. Most strength gains for a beginner comes from neural adaptation, not muscle growth. That is, your body learns to use its muscles more efficiently. There's also two types of hypertrophy, sarcoplasmic and myofibrillar.

[@triton62674]

+edheldude So if you were to diet and weight train at the same time when what would happen?

[@edheldude]

A beginner can gain strength and muscle while lifting in moderate caloric deficit. More advanced lifters can't.

[@KnightB97]

+triton62674 Well that depends on what diet. Powerlifters (performance athletes, setting goals on lifting X wight for Y reps for Z exercise) on a "cut", eating to try to keep muscle mass and burn fat on workouts, Will experience a decrease in preformance, meaning hitting weight goals will get much harder, and failure is highly possible. on a cut you usually eat alot of protein, less fat and carbs and overall less calories. That means that they give their muscles what they need to recover, but cut the carbs, so that the body will burn the fat for energy instead of carbs, which are much easier to use than fat and therefore on a higher priority to the body. All athletes will feel much less energetic on workout while on a diet. bodybuilders will look smaller after a cut but their muscle will be much more defined. But the cut doesnt affect them as much because their workouts arent usually based on performance.

[@michaelhutchinson1789]

+edheldude My thoughts exactly. The reason a 6 year old gymnast can perform a planche is because of neural strength not muscle size. It's a great point that should be explained to everyone before they start training/working out.

[@JeffreySiegelwellness]

+edheldude thanks for comment about hypertrophy vs strength. I tried to address this more clearly in the "Dig Deeper" section on the TEDed site:. It reads: "While there is meaningful overlap between muscle size and strength, it is possible to gain strength without increasing muscle size. Strength can be achieved by upgrading your central nervous system to recruit and coordinate more existing muscle fibers. Changes in the fascia, tendons, and bones also affect the contracting muscles ability to transmit force. Bodybuilding techniques are primarily concerned with building new muscle fibers. If you're looking for ways to train for size opposed to strength, read "Size Vs. Strength: Are You Lifting Too Heavy?""
