Muscles
We have over six hundred of them
They make up between one third and one half of our body weighting and along with connective tissue
They bind us together
Hold us up and help us move
And whether or not body building is your hobby muscles in your constant attention
Because the way you treat them on a daily basis determines whether they will weather or grow say you're standing in front of a door
Ready to pull it open
Your brain and muscles are perfectly poised to help you achieve this goal
First your brain sends a signal to motor neurons inside your arm
When they receive this message
They fire causing muscles to contract and relax
Which pull on the bones in your arm and generate the needed movement
The bigger
The challenge becomes the bigger
The brain's signal grows and the more motor units
It rallies to help you achieve your task
But what if the door is made of solid iron at this point
Your arm muscles alone won't be able to generate enough tension to pull it open
So your brain appeals to other muscles for help you plant your feet tighten your belely that tense your back generating enough force to yg it open
Your nervous system has just leverage to the resources
You already have other muscles to meet the demand
While all this is happening
Your muscles fibers undergo another kind of cellular change
As you expose them to stress the experiened microscopic damage
Which in this context is a good thing
In response the injured cells release inflamatory molecules called sidekinds that activate the immune system to repair the injury
This is when the muscle building magic happens the greater that damage to the muscle tissue
The more your body will need to repair itself the resulting cycle of damage and repair eventually makes muscles bigger and stronger
As they adapt aggressively greater demands
Since our bodies have already adapted to most everyday activities those generally don't produce enough stress to stimulate new muscle growth
So to build new muscle a process called hypertrophy
Our cells need to be exposed to hirer workloads
Than they are used to in fact
If you don't continuously expose your muscles to some resistance
They will shrink a process known as muscular atrophy in contrast edepoa the muscle to high
High degree of tension
Especially well like muscle is linthening also led an effecentric contraction generates effective conditions for new growth
However muscles rely on more than just activity to grow withbody proper nutrition
Hormones and rest
Your body would never be able to repair damage
Muscles fibres
Protein in our diet preserves muscle mass by providing the building blocks for new tissue in the form of a mino assets
Adequate protein intake along with naturally occurring hormones like insulent
Like growth factor and test tossterran help shift the body into a state
Where tissue is repaired and grown
This vital repair process mainly occurs
When we're resting especially ate at night while sleeping
是的是是的
Gender and age affect this repair mechanism
Which is why young men with more test tostron have a leg up in the muscles building game
Genetic factors also play a role in one's the ability to grow muscles
Some people have more robust immune reactions to muscle damage
And are better able to repair and replace damage
Muscle fighers increasing their muscle building potential
The body responds to the demands
You place on it
If you tear your muscles up eat right rest and repeat
You'll create the conditions to make your muscles as big and strong as possible
It is with muscles
As it is with life
Meaningful growth requires challenge up stress
