You 00:00:00
Hey friends as you can see I was exercising to grow some muscles as it needs constant attention 00:00:11
But before you jump into the exercising zone and start working out 00:00:19
You need to learn about muscles and how they grow so zoom in 00:00:24
Muscles? You have over 600 of them. 00:00:30
They come in all shapes and sizes to bind you, hold you together and help you move and lift heavy backpacks. 00:00:36
You control some of your muscles, while others do their jobs without you thinking about them at all. 00:00:45
But one thing is sure and that is they need your regular attention 00:00:53
..because the way you treat them will determine their condition.. 00:00:58
..if they will grow or shrink with time. 00:01:02
But the big question is, how do the muscles grow? 00:01:05
Imagine you are about to lift a box of yummy cookies. 00:01:11
Your brain and muscles are aligned to help you to do the task at hand. 00:01:15
First, your brain will send signals to the motor neurons in your body. 00:01:20
When they receive the message, they cause the muscles to contract and relax.. 00:01:26
..which pull on the bones in your body, resulting in needed movement. 00:01:32
But, what if this box is filled with stones? 00:01:39
At this point, your arm muscles will find it hard to generate enough tension to lift.. 00:01:43
..and exposing it to stress, causing little damage.. 00:01:50
which in this case is a good thing these damaged cells then release 00:01:54
inflammatory molecules called cytokines that activate the immune system to 00:02:00
repair the injury this is where your muscles building process happens the 00:02:06
more the damage to the muscle tissues the more your body needs to fix itself 00:02:13
Eventually making your muscle bigger and stronger. 00:02:18
But your muscles depend on more than just exercising or playing to grow. 00:02:23
Without proper nutrition and rest, it will be hard for your body to repair the damaged muscle fibers. 00:02:30
So, play, eat, sleep, repeat. 00:02:38
That's the mantra for a healthy body. 00:02:42
Trivia Time! 00:02:45
Did you know that there are three different types of muscles in your body smooth muscle cardiac muscle and? 00:02:48
skeletal muscle 00:02:56
Skeletal muscles are voluntary muscles, which means you can control what they do 00:02:58
Whereas smooth and cardiac muscles are involuntary muscles that mean they move on their own without 00:03:03
thinking about them 00:03:11
It's question time! 00:03:13
