Training menu for strengthening back muscles! Explanations for each part, including the latissimus dorsi and trapezius muscles

First, you need to know the three main muscles that make up your back!

To effectively train your back, it's important to first understand the structure of the muscle.
There are many muscles in the back, and the muscles around the spine at the center of the body play an important role in all human movements.
Knowing the names, locations, and functions of muscles will make it easier to be aware of which parts of your body you are working during your workout.

Here, we will explain the structure of the three main muscles that make up the back: the latissimus dorsi, the trapezius, and the erector spinae, and the role each muscle plays in body movements.

The latissimus dorsi muscle that creates an inverted triangle body shape

The latissimus dorsi is the largest muscle in the back, stretching from the armpits to the sides and waist in an inverted triangle shape.
It is mainly used to pull the arms behind or under the body, or to pull objects or people towards oneself.
By training these muscles, your back will become wider and your waist will appear tighter, creating the so-called "inverted triangle" silhouette.

The latissimus dorsi is also involved in the thickness of the body, and through training it is possible to get a strong, thick back.
It often moves in conjunction with the teres major muscle located near the armpit, and can be stimulated effectively with exercises such as pull-ups and rowing.

The trapezius muscle covers the shoulders and upper back

The trapezius is a diamond-shaped muscle that stretches from the base of the neck to the shoulders and up the middle of the back.
This muscle is divided into three sections: upper, middle, and lower, each with a different function.
The upper trapezius muscle is involved in shrugging the shoulders, the middle part in bringing the shoulder blades inward, and the lower part in pulling the shoulder blades down.

This area is easily tense due to desk work and smartphone use in daily life, and is often the cause of stiff shoulders.
Therefore, training the trapezius muscles in a balanced manner not only improves the line of the shoulders, but also supports the correct movement of the shoulder blades, helping to prevent and improve stiff shoulders.

Maintaining good posture: Erector spinae muscles

The erector spinae is a collective term for several muscles that run vertically down both sides of the spine, from the back of the neck to the pelvis.
As its name suggests, it constantly works to support the spine, keeping it upright and maintaining good posture.
It also plays an important role when leaning forward, bending backward, bending sideways, and twisting, and contributes greatly to the stability of the core.

If these muscles are weak, they will not be able to properly support the spine, causing a hunched back and arched lower back, and increasing the risk of developing back pain.
By strengthening your erector spinae muscles, your core will be strengthened, your posture will be stabilized, and the strain on your lower back will be reduced, making it easier to perform various movements in your daily life.

4 benefits of strengthening your back muscles

The back muscles are one of the largest in the body, so the changes that come from training them are very noticeable.
The benefits of this not only include achieving the muscular physique that men desire, but also greatly contributing to the development of the toned, beautiful body lines that women aspire to.

Especially for those in their 30s and beyond, when their bodies are more susceptible to changes, back training offers many benefits for maintaining an ideal physique and living a healthy lifestyle.
Here are four specific benefits of strengthening your back muscles:

Benefit 1: Get a muscular, inverted triangle shape from behind

By focusing on back training, especially the latissimus dorsi muscles, you can achieve an inverted triangle silhouette that widens from the shoulders to the waist.
This body type gives the impression of being strong and muscular, with broad shoulders and a relatively slim waist.
Your back, which you cannot see directly, greatly influences the impression others have of you, and a well-trained back can also lead to confidence.

By training, you can build muscle throughout your back, which will improve your silhouette when wearing a suit or T-shirt, and give you an attractive physique that looks good from any angle.

Benefit 2: Improves posture and helps maintain a beautiful posture

If you continue to bend forward due to desk work or using a smartphone for long periods of time, the muscles in your back will weaken and you will be unable to support the weight of your head, making it easier for you to develop a hunched posture.
Slouching not only looks bad, but can also cause stiff shoulders and shallow breathing.

By strengthening your trapezius and erector spinae muscles, your shoulder blades will be positioned correctly and your ability to support your spine will improve.
This will naturally straighten your curved back and help you maintain a beautiful posture with your chest out.
It can also help improve swayback and correct body misalignment.

Benefit 3: Prevents and improves painful shoulder and back pain

Most shoulder and back pain is caused by muscle tension and poor circulation due to staying in the same position for a long time.
In particular, if the back muscles are weak, excessive strain is placed on the neck, shoulders, and lower back muscles in order to support the head and upper body, making symptoms such as stiffness, pain, and tension more likely to occur.

When you train your back, the muscle pumping action increases blood circulation and relieves muscle tension.
Strengthening the erector spinae muscles also stabilizes the core and reduces strain on the lumbar vertebrae, helping to prevent lower back pain.
By reducing the accumulation of muscle fatigue, you can expect to be relieved from chronic pain.

Benefit 4: Improves basal metabolism and makes it easier to lose weight

Basal metabolic rate is the minimum amount of energy required to maintain life, and the more muscle mass you have, the higher it becomes.
The latissimus dorsi, trapezius, and erector spinae muscles in the back are some of the largest muscle groups in the body, and training these muscles is extremely effective in efficiently improving your basal metabolic rate.

When your basal metabolic rate increases, the number of calories you burn even when you are at rest and not exercising increases.
As a result, even if you eat the same food, your body will become less likely to gain weight and more likely to lose weight.
When it comes to losing weight or maintaining your shape, incorporating back training is a very effective approach.

[No equipment required] Bodyweight back exercises you can do at home

You can start back training at home without any equipment, without having to go to the gym.
Bodyweight training, which uses your own body weight as resistance, has the appeal of being easy to do, with little risk of injury, even for beginners.

Even if you find difficult exercises like pull-ups difficult, the exercises we will introduce here can be easily done in about 5 minutes per session.
First, start by focusing on proper form and adjusting the number of repetitions to suit your level.
It is difficult to focus on the muscles in your back, so the key is to move slowly and feel the muscles contracting.

"Back extension" stimulates the latissimus dorsi muscles

Back extensions are primarily known as an exercise that trains the erector spinae muscles, but depending on how you perform them, they can also effectively stimulate the latissimus dorsi muscles.
First, lie face down on the floor and place your hands behind your head or next to your ears.
Place your feet shoulder-width apart and place your toes on the floor.

From there, slowly arch your upper body while exhaling, and pause for a moment when you feel your back muscles contract.
Then, inhale and slowly return to the starting position.
The key is to lift your upper body using the strength of your back, especially the lower erector spinae and latissimus dorsi muscles, without arching your lower back too much.
It is important to control the movement using muscle power, without using recoil.

"T-Raise" that targets the trapezius muscle

T-raises are an effective exercise that primarily targets the middle and lower trapezius muscles, as well as the posterior deltoid muscles in the shoulders. To perform this exercise, lie face down on the floor with both arms extended out to the sides at shoulder height, forming a T with your entire body. Keep your palms facing the floor. Next, exhale and slowly lift both arms off the floor, focusing on centering your shoulder blades. Pause once your arms are slightly above shoulder height, making sure you feel a strong contraction in your trapezius muscles. Then, inhale and slowly lower your arms in a controlled movement. Repeating this movement effectively stimulates the trapezius muscles, leading to a beautiful line of the shoulder blades and a strengthened upper back. The key to achieving maximum effectiveness is to focus on the movement of your shoulder blades rather than relying on arm strength, performing the exercise carefully and without using momentum. Practice without excessive strain, focusing on muscle movement.

Bird Dog: Works the erector spinae muscles

Bird dog is a training exercise that improves the stability of the entire core, focusing on the erector spinae muscles.
First, get on all fours with your hands directly under your shoulders and your knees directly under your hips.
At this time, be sure to keep your back parallel to the floor and be careful not to arch or round your lower back.
Next, while keeping your stomach tight, slowly stretch your right arm and left leg forward and backward, keeping them in a straight line with your body for a few seconds.

Do not hold your breath while doing this, just breathe naturally.
It is important to maintain balance so that your body does not wobble.
Then slowly return to the starting position and repeat the same movement with your left hand and right foot.

"Superman" exercise: focusing on the entire back

As the name suggests, the Superman is a training exercise in which you assume a pose similar to Superman flying through the air, and it simultaneously trains the muscles of your entire back, including your latissimus dorsi, trapezius, and erector spinae.
First, lie face down on the floor with your arms in front of you and your legs straight behind you.
Keep your gaze on the floor and your neck relaxed.

From there, exhale and slowly lift both arms and legs off the floor at the same time.
Hold this position for a few seconds, feeling the muscles in your back contract.
At this time, it is important to be aware of not arching your back too much, and lifting your body within a comfortable range will help prevent injury.
Then, inhale and slowly return to the starting position.

[Equipment included] Training menu to work your back muscles with dumbbells

Once you get used to bodyweight training, you can increase the load by using dumbbells to further increase your strength and muscle mass.
At the gym, you can do a variety of exercises using barbells, specialized machines, and cable lat pulldowns, but if you have dumbbells, you can effectively work your entire back at home.

Using dumbbells provides a stronger stimulus to your muscles than you can get with your own body weight, allowing you to build a strong back more efficiently.
Here we will introduce four typical back training exercises using dumbbells.

"One-hand rowing" to thicken the latissimus dorsi muscles

One-handed rowing is an exercise that focuses on the latissimus dorsi by pulling a dumbbell with each hand.
Place your left hand and knee on a bench or chair and lean forward so that your back is parallel to the floor.
Start with your right arm held down naturally, holding a dumbbell in your right hand.
As you exhale, focus on squeezing your shoulder blades together and lift your elbows high, bringing the dumbbells up to your sides.
Once you feel a strong contraction in your lats, hold that position for a moment.

Then, inhale and slowly return the dumbbells to their starting position without relaxing your muscles.
Repeat this movement on the other side.

The bent-over row strengthens the entire back

The bent-over row is a rowing exercise performed with dumbbells in both hands, and is a very effective exercise that allows you to train the major back muscles such as the latissimus dorsi, trapezius, and erector spinae all at once.
First, stand with your feet shoulder-width apart and your knees slightly bent.
Keeping your spine straight, lean your torso forward as if you are bowing.

Holding dumbbells in both hands with your arms extended, exhale and pull your shoulder blades together up towards your solar plexus.
At this time, it is important to tighten your abdominal muscles and stabilize your core so that your waist does not curve.
Focus on pulling with your back muscles and slowly return to the starting position.

Dumbbell shrugs: Focus on training the upper trapezius muscles

Dumbbell shrugs are a training exercise that focuses on the upper trapezius muscles by shrugging your shoulders.
It is effective in creating a muscular neck and full shoulders.
First, stand with your feet shoulder-width apart and hold a dumbbell in each hand.
Let your arms hang naturally at your sides and relax.

From this position, exhale and shrug your shoulders as high as possible, bringing them closer to your ears.
Once you feel a strong contraction in your trapezius muscles at the top, hold that position for 1-2 seconds.
Then, inhale and slowly lower your shoulders back down to the starting position, as if you are resisting gravity.
The key is to do this using only the up and down movement of your shoulders, without using any arm strength.

Dumbbell deadlifts stimulate the erector spinae muscles at the same time

The dumbbell deadlift is a full-body exercise that focuses on the erector spinae muscles, working the entire back and even the muscles of the lower body such as the buttocks and back of the thighs, by lifting dumbbells off the floor.
First, stand with your feet shoulder-width apart and place a dumbbell between your feet.
Keeping your back straight, lean forward from your hips and bend your knees to grab the dumbbells.
As you exhale, push your chest out and press the soles of your feet into the ground to stand up.

The most important thing to remember is to keep your back straight throughout the movement.
Once the dumbbells have passed your knees, raise your torso up.
Lower it in the same trajectory, slowly and with control.

Important points to maximize the effectiveness of back training

Back training doesn't get its full benefits just by doing a certain number of repetitions.
It is especially difficult to move your back while watching it with your own eyes, and if you are not conscious, you tend to use force from other parts of your body.
To avoid wasting your precious training time, it's important to understand a few key points to maximize your results.
By taking a comprehensive approach that includes not only proper form but also how to focus on your muscles, how to set the load, and how to take rest, the quality of your training will improve dramatically.

Train with awareness of the area you are training

In order to maximize the effectiveness of your training, it is very important to be aware of the muscles you are training.
This is called the "mind-muscle connection," and by concentrating commands from the brain on the target muscles, you can recruit more muscle fibers and stimulate them more strongly.

For example, when performing rowing exercises, instead of simply pulling the dumbbells with your arms, imagine the movement of your back muscles, such as "contracting your latissimus dorsi and pulling your elbows."
Checking your form in the mirror or touching the area you are actually working is also an effective way to raise your awareness.
Whether or not you have this awareness will greatly affect the speed of your growth.

Imagine pulling with your back, not with the strength of your arms.

When training the back, especially exercises that involve pulling movements, beginners often make the mistake of relying too much on the strength of their arms.
If you use your arm muscles, such as your biceps, to pull the weight, the stimulation to the latissimus dorsi and trapezius muscles, which should be targeted, will be significantly reduced.
To prevent this, it is essential to always keep in mind that you are pulling with your back.

Specifically, when starting the movement, first bring your shoulder blades together, and then be conscious of pulling your elbows back along your torso, which will naturally use your back muscles.
Think of your arms as merely hooks for hanging the weight, and try not to grip too tightly.

Adjust the number of repetitions and load of your training to suit your goals

The appropriate number of repetitions and load settings will vary depending on the purpose of your training.
Generally, if your goal is to increase muscle mass (muscle hypertrophy), it is considered effective to set a weight that you can reach your limit with around 8 to 12 repetitions.
If your goal is to improve your muscle strength and be able to handle heavier weights, you should aim for 1 to 5 repetitions of heavy weights and low repetitions. If your goal is to improve your muscle endurance, you should aim for 15 or more repetitions of light weights and high repetitions.

By clarifying the type of body you are aiming for and creating a training program with the repetitions and load that suits your purpose, you can approach achieving your goal more efficiently.

Allow enough rest days to promote muscle growth

Muscles become thicker and stronger as muscle fibers damaged during training are repaired through rest and nutrition.
This phenomenon is called "supercompensation" and is an essential process for muscle growth.
Supercompensation generally takes about 48 to 72 hours, so training the same body part every day does not give your muscles enough time to recover and may actually hinder your growth.

After working large muscle groups like your back, it's recommended to take at least two rest days.
Quality rest is just as important to muscle growth as training.

Stretching before and after training to prevent injuries

Stretching before and after training is important to continue training safely and maximise its effectiveness. Before training, it is recommended to do "dynamic stretching", which involves warming up the muscles while moving the body, similar to radio calisthenics, and increasing the range of motion of the joints. This allows the muscles and joints to move more smoothly, which is thought to improve performance during training and prevent injuries.

On the other hand, after training, it is common to perform "static stretching," which involves slowly stretching muscles to relieve tension. Static stretching can increase muscle flexibility and have a relaxing effect. It has also been pointed out that it may help recover from fatigue by improving blood circulation. However, some recent research suggests that static stretching after training may have limited effect on reducing muscle soreness and restoring muscle strength. Therefore, in addition to recovering from fatigue and relieving muscle pain, static stretching should also be performed for the purposes of relaxing the mind and body and maintaining and improving flexibility.

My Feelings, Then and Now

The muscles in your back are not only important for your appearance, but also play a vital role in maintaining a healthy body.
It is important to understand the three main muscles - the latissimus dorsi, which creates an inverted triangle shape of the body; the trapezius, which is involved in posture; and the erector spinae, which supports the core - and to train each of them effectively.

The quickest way to achieve your ideal body is to practice equipment-free bodyweight training or dumbbell-based training that suits your environment and level, and to be aware of the key points to maximize the effectiveness of your training.
By paying attention to the area you are training, using the correct form, and getting enough rest, you can train your back safely and efficiently.
