Most people think sore muscles mean progress, but soreness is mostly inflammation and has little to do with actual growth. In this video, you will learn what really drives hypertrophy and the simple recovery habits, like sleep, protein, and smart training frequency, that decide whether your workouts actually build muscle.

3:24 for that test to be really good, it would need to be done on the same person first sleeping 8h during the week, then the next week only sleeping 5hours, becose some people need sleep less or more than others. And if you eat too much vegetables, you will need to eat more prots than someone eating a normal amount becose fibers make you poop more and absorb less nutriments. Also a little bit of sugar in your prot shake or when you eat your prots can help you since the sugar will make you absorb more nutriments.
Look eddie halls past strongman's diet compare to some fitness bodybuilder on internet who tell you to eat as much vegetables as you want. Of course you will not need as much calories than a strongman, but you can simply divide it to an amount that go well for you while you keep the same food proportion he's eating. You will have a diet that you can still enjoy while at same time been healthy for growing strenght (specialy for those who like to eat tasty things and don't consider food just like a fuel)
5:27 yes people mistake gaining endurance and gaining muscle strenght.

Man I just eat and eat. If been getting bigger. I have a fast metabolism idk if that helps. I eat like ALOT big ass plates and bowls but I’m not a big guy I’m pretty skinny lol but with how I’ve been working out at home I’ve been looking like I’ve been bulking for a year or something. I’m not eating like that because I’m working out thought I’ve always eaten that much. I just thought it would be a good idea to start working out. Thing about me is I get like 5-6 hours of sleep which SUCKS 😭😭😭

I started my fitness journey 5 days ago and have been staying disciplined since day one. I want to see how far I can push myself. I'm feeling motivated and decided to give this app a try. 💪

Eccentric aint better than concentric🥀

So why do athletes train every single muscle 6 days a week
@AndriaCercbadzeBro sounds like FlameFrags
@JericArtsMCCan anyone who knows confirm that failure is not only not necessary but basically also not good. A time ago someone told me that getting sore is not having done a good warmup but that is not true
@G.lazaridis1993Thanks 😊

@Richi_DunkulSo don't eat before working out?
@tiragd928Woww , what a data 🔥😮
@TahaHdvPls tutorial
@Gamer-u9h1tThis video is such a breath of fresh air—incredibly insightful and truly inspiring! 🌌 I’m particularly drawn to your analysis of the "law of consistency" at; it’s the exact perspective I think so many people need to push through the toughest stages of personal growth. The way you clarified the importance of "focusing on the process rather than the outcome" at was a real lightbulb moment that helped me reshape my daily mindset. 💡
Furthermore, your advice on how to handle failure at really hit home and helped me realize that every setback is an essential part of success. Thank you for putting so much effort into creating such high-quality, valuable content for the community. This is definitely a video I’ll be coming back to whenever I need a boost of motivation. Looking forward to seeing much more meaningful content from you!
The science of recovery is often overlooked—great video.
@BodyMechanicsMD"This video is a total mind-blowing experience—it completely shattered all my misconceptions about muscle growth! 🧠 I love how you keep it concise and strictly science-based; it’s incredibly engaging. I had a massive realization at [00:00:52] learning that muscles just need mechanical tension to trigger the MTC1 signal, rather than being torn or intensely sore to grow. 🎯
Also, your tip at [00:02:47] about slowing down the eccentric phase to at least 3 seconds is an absolute game-changer for maximizing tension—something I’ve been totally rushing through until now. ⏱💪 Fast-paced editing, straight to the point, and highly actionable!
Huge thanks to the team for delivering such top-tier, high-value content. Keep crushing it, this channel deserves to blow up even more! 🚀💎🔥"
What happens if you’re one of those people who just can’t get more sleep? My body wakes me up over and over every 15 minutes after about 5 and a half hours. If I want more than that, I need to get drunk lol.
@whatfoodeatsSo thats why im not getting bigger thanks
@kingkong-l8f1qwait i dont sleep hahah oh no
@DeviSenpai❤❤
@JadonMarcusyea you can get stronger and stronger and see little to zero growth
look at anatoly... seriously, if u want MASS you have to train hypertrophy, not strength.
tje fiber break down explained works for both ways.
I am 32 years old and have recently started thinking seriously about my health and physique. To be honest, I have never been a gym person. I am vegetarian, naturally skinny in some areas, carrying extra fat around my stomach and chest, and I often feel self-conscious about my appearance.
What is bothering me most is that even a 5 kg dumbbell feels heavy. I walk into the gym and see teenagers and youngsters lifting weights so effortlessly that it looks like a cakewalk. Meanwhile, I struggle with basic exercises, and sometimes my shoulders start hurting after simple movements. It makes me wonder if I am too late to start.
I am not in a rush to build a six-pack or transform overnight. I know good things take time. But I genuinely want to understand:
• Is 32 too late to build an appealing physique?
• Can a complete beginner still gain muscle and lose belly fat at this age?
• How long does it realistically take for someone starting from zero?
• As a vegetarian, what affordable foods should I focus on?
• Is shoulder discomfort normal in the beginning, or should I be concerned?
• How do you stay motivated when everyone around you seems stronger and fitter?
Some days I feel excited about this journey. Other days I doubt myself and wonder whether my body is capable of changing. I want to become stronger, healthier, more confident, and proud of the person I see in the mirror.
If you started late, struggled in the beginning, or transformed yourself after your 30s, I would genuinely appreciate hearing your story. I am looking for honest guidance, realistic expectations, and perhaps a little reassurance that I haven't missed the bus.
Thank you for reading.
I also cross-checked it with ChatGPT. I used to skip protein on rest days to save money, but oh boy, I was missing out on gains. Today was my rest day, so I took all my protein and only did 3 pull-ups and a 1-minute hang. My muscles are definitely sore. I'm not giving up—sleep, eat, wake up, and destroy. 💪🔥 and thanks for conforming yellow dude love from india
@freefall_910People don't know this ( which is wild to me ) but when you do push ups, correct push ups, you actually activate around 20+ muscles in your body.
Most people do 25 to 30 push-ups using momentum, not really using muscle tension.
I'd rather do 10 pushups slowly ( 4 to 6 seconds ) than 30 fast and the reason is quite simple... muscles under load and tension will grow a lot faster and stronger.
Try this, go down slowly, hold when your chest is almost down, then after 1 or 2 seconds come back up and I promise you, those pushups you will feel, not to mention you won't be able to do that many.
Happy training !
Oh yeah I love when my muscle fibers lengthen ohhh yeeeeeah
@Revealingstorm.🇬🇷🇬🇷🇬🇷💪💪💪
@GT170.Does that means if i don't have enough protein i should not train cuz it won't build muscles no?
@zoro_to978Main focus:
Focus on 1 part of the body for 1 day
Focus on another body?
I don't know how I'm supposed to suddenly be good at sleeping. I've been practicing all my life and still can't do it.
@myautobiographyafanfic1413Picture 😂😂😂
@nikhilkalamsare6768Channel called brick body is using AI to ripoff your content bro. Just released a nearly word for word copy about a week ago
@billremington628748 hours from end of workout… wouldn’t that put you close to every other day?
Monday morning - Wednesday morning is 48 hours…
So, negatives... positives.
@TheOvermindStarcraftMe watching this in train going to work and after 8hr work immediately go for workouts
@ofordileonochie1448"What actually makes muscles grow" Steroids
@durdevdan6947The 48-hour synthesis window vs. soreness peak disconnect is the clearest explanation I've seen for why "rest until it stops hurting" kills frequency gains. I animate calisthenics mechanics on my channel, and the eccentric point is the one I keep returning to - muscles handling 40% more force on the way down means the part most people rush through is literally the most productive rep they'll do all session.
@GravityBroXthanks ❤
@AnvilBuiltFitnessWell done
