Well, these terms are short for some of the main skeletal muscles of the body.
It’s necessary to know about these main skeletal muscles if you’re committed to fitness and want to see results. This is because during your workouts you won’t just train aimlessly but work specific muscles or groups of muscles. You don’t want to be the odd one just doing workouts aimlessly without knowing what you’re doing and why.
It’s also important to know the anatomy of the main workout muscles if you want to do your workouts correctly and efficiently.
We have already talked about “How our Muscles Work“. If you haven’t read the article, I recommend it. You may also want to read “Why You need to be Fit” and “Fitness Basics, Start with These 10 Things First“.
We have about 650 skeletal muscles in the body. The Skeletal muscles help our body function properly and move. Some are large while others are small and may be irrelevant to providing the main function or provide other functions.
The main skeletal muscles are the muscles you see that pop out in bodybuilders or fitness models. These are also the muscles that bring out the shape or aesthetic body as you might call it. Well, the majority don’t want to be in this league but the majority of people still want to be fit.
For the purpose of this article, we will be dividing the main muscles into 4 groups
MAIN MUSCLES OF THE UPPER LIMB
In the upper limb, there are 3 important muscles you should know.
Biceps. This is the large muscle in the front of the arm. It is the muscle that protrudes when you flex the arm.
Triceps. It is the large muscle in the back of the arm. It contracts when the arm is extended.
Deltoid. This is the round and strong muscle forming the rounded contour of the shoulder. It’s shortly called the “delt”.
MAIN MUSCLES OF THE LOWER LIMB
In the Lower limb, there are 3 areas of focus: The butt, the thigh and calf muscles.
Three main muscles make up the Gluteus muscles or the buttocks – gluteus maximus, medius and minimus. They are shortly referred to as “Glutes”.
This is the most prominent muscle of the thigh. It is located in the front and sides of the high.
It is simply known as the “Quads”. Four heads form this muscle; rectus medialis muscle in the middle, vastus medialis muscle medial to rectus medialis, vastus lateralis muscle lateral to rectus medialis and vastus intermedius muscle under rectus medialis muscle.
The gastrocnemius muscle and the soleus muscle form this muscle. The gastrocnemius muscle is the most prominent muscle of the calf, forming the bulge. The soleus muscle is a small flat muscle that lies underneath the gastrocnemius muscle.
MAIN MUSCLES OF THE TRUNK
Pectoralis major and minor muscles
The main muscles making the chest are the pectoralis major and minor muscles shortly known as the “Pecs“.
Anterior serratus muscle
This muscle is located on the sides of the chest below the pecs. It’s closely attached to the ribs in this region.
Rectus abdominis muscle
Commonly known as the 6 pack muscle. It is the most prominent muscle of the abdomen.
This comprises the external and internal oblique muscles. It is located laterally on either side of the rectus abdominis muscle.
MAIN MUSCLES OF THE BACK
This is a flat and large muscle of the back and neck. It has the shape of a trapezoid and covers most of the upper back and posterior of the neck. “Traps” is the slang or short form for this muscle.
Latissimus Dorsi muscle
This is the largest muscle of the back. It stretches from the middle of the back to the sides, behind the arm and is partly covered by the trapezoid muscle. This muscle greatly contributes to the V shape famous in bodybuilders. “Lats” is the slang or short form for this muscle
There are a lot of muscles in the human body with several functions. It’s not important to know all but it’s necessary to know the major ones. This enhances fitness and you will use it as a gauge to check your progress. It’s also necessary because you will have to do specific workouts for specific groups of muscles.
In our upcoming articles on fitness, we are going to elaborate on specific workouts for specific groups of muscles and region of the body.
