The conventional wisdom about building muscle has been turned on its head. For years, trainers have advocated for a "tear and repair" system, where working out causes micro-tears in muscle fibers, which trigger the body's repair processes to make muscles bigger and stronger. However, recent science suggests that this approach is not entirely accurate.
In reality, the primary driver of muscle hypertrophy - or an increase in muscle size - is mechanical tension. When you lift a weight that's heavy enough, it stretches the membrane surrounding your muscle cells, triggering specialized sensors called mechanoreceptors to detect the stretch and activate the mTOR pathway, which signals the cell to start building new tissue.
While muscle damage can contribute to hypertrophy, it's not the main factor. In fact, many people can build significant amounts of muscle without adding much extra strength, as long as they're using a weight that creates high tension but performing enough repetitions to generate metabolic stress.
There are two types of muscle hypertrophy: myofibrillar and sarcoplasmic. Myofibrillar hypertrophy increases the number of myofibrils, which contract to lift weights, resulting in increased strength. Sarcoplasmic hypertrophy expands the volume of fluid inside the muscle, leading to a larger muscle size without added strength.
The key is finding the right balance between mechanical tension and metabolic stress. A combination of heavy weightlifting with sufficient repetitions can lead to optimal muscle growth. However, it's not necessary to push yourself to the limit or even close to it.
Coaches often recommend progressive overload - making muscles do more work - but there are many ways to achieve this, such as increasing repetitions in each set, using heavier weights, reducing rest time between sets, and so on. Gradually increasing the intensity over weeks or months will result in both strength gains and slight muscle growth.
The most effective growth happens when you combine myofibrillar and sarcoplasmic hypertrophy, but it's not a guarantee that everyone will see results. It's also essential to remember that genetics play a significant role, and some people may struggle to build significant amounts of muscle regardless of their training regimen.

. I mean, we've all heard it from our fitness buddies or the gym rats who swear by heavy weights and intense workouts. But honestly, I think the real magic happens when you find that sweet spot of tension and stress in your muscles 
.
. It's like, our bodies are wired to respond to challenges, not just pain or damage 
. And when you're lifting weights that push you a bit too hard but still within your limits, you're actually building those muscles in a way that's sustainable and effective 
.
. You don't need to go full-on beast mode every time you hit the gym 
. A good mix of weights, reps, and rest days can take you far 
. And yeah, genetics play a role, but that doesn't mean you're stuck with your body type 
. With patience, persistence, and the right approach, anyone can build muscle and feel amazing about it 
.
. I mean, we've all been told to 'push ourselves' and 'go heavy or go home', but what if that's just not how it works? 
It's like, we're supposed to believe that just because you lift weights, your muscles will automatically get bigger and stronger... and sure, maybe that's true for some people, but what about the rest of us who just don't have that kind of genetic makeup?
, but let's not forget that there are other factors at play here. Like, how much do we really know about what happens inside those muscle cells when we're lifting weights? It's time to dig deeper and ask some questions 
. Maybe instead of just trying to build muscle, we should be focusing on building a healthier relationship with our bodies 
.
and letting your muscles do the work 
. And can we talk about how easy it is to get enough reps without actually being able to lift super heavy? Like, I just chill on my fitness journey and still see gains 
. My fave trainer (I only train with them 
) says progressive overload is key, but now I'm like "wait, there are other ways to do that?" 
. This whole thing has me super excited for a new workout routine 
!
.
. But for those who do put in the work, I think this new info is gonna make training way more effective 
.
... and dont 4get genetics play a big role too 
. Like, what took them so long to figure out? This whole "mechanical tension" thing just sounds like an excuse for people who don't wanna put in the actual work 
... like, no thanks. Can we just stick with the tried-and-true methods already?
. Maybe what matters most is just finding the right balance between how hard you're pushing yourself and resting time 
️.
.
?
. The thing is, genetics are still a major player here, so if you're not blessed with the right genes, good luck building significant muscle mass (just ask the thousands of people who've spent years trying and struggling).
. I think the whole "tear and repair" thing was just a myth to justify people feeling like they need to push themselves way too much 
. I've seen people get results with different training methods, and it's clear that it's not one-size-fits-all
