How to get a six-pack in ten minutes? How to lose ten pounds in one week? How to burn 500 calories in an hour?

Training is a major focus these days. Questions like these are normalized in our everyday lives and the big focus around exercise and appearance is getting bigger.

However, do we know what is happening with our bodies and especially with our minds when we exercise?

By looking at how the human body is built and how it responds to exercise, we can find an answer to the main question.

What is exercise doing to your body? In this text, we will also do some research on the importance of recovery, if age has any effect, and how your mind responds to training.

With some background information and some additional knowledge, we can understand what exercise is doing to our bodies and if it is worth the effort.

What Is a Muscle?:
To understand the theory of exercise we need to understand the human body. The human body consists of many muscles.

However, what exactly is a muscle? A muscle is formed when specialized long and tubular cells bind together.

These are what we call muscle fibers. This binding process is called myogenesis, and that is because these specialized cells are known as myocytes.

How Do Muscles Work?
We also need to understand how the muscles work to understand how the body is working.

The most important task of the muscles is to create movement. Every day we perform different movements, and our everyday life depends on being able to move.

Movement is a complicated process where the muscles, skeleton and nervous system have to work together. To be able to do this, the muscles are depending on oxygen and nourishment.

Utdrag
The Muscle’s Response to Movement and Exercise:

Muscles grow when we stress the muscles out of their regular comfort. When this happens, the body works hard to maintain a stable internal environment.

This environment is called homeostasis (Jancer, 2018). Stimulation of muscle breakdown and protein synthesis begins when you start exercising with resistance.

Protein synthesis helps to rebuild muscles and the simulations are the ones that leave you with bigger and stronger muscles.

However, why do the muscles get bigger when you break them down? Exercise damages muscle tissue (Waehner, 2020), and after exercise, the muscle is torn down.

That is when the repair process begins. This process makes the muscles grow bigger and stronger.

Since exercise damages the muscles, the body is trying to repair it so next time it will be able to "protect" itself better.
