• April 23 2024

Barbell curls are an effective way to train your upper arms. You can apply a high load using equipment even in a limited space such as at home. However, when you try to start barbell curls at home, you may have questions about how to choose the right weight and how to train effectively.

In this article, we will explain in detail the appropriate weight for barbell curls and how to maximize their effectiveness. Learn more about barbell curls and aim for your ideal upper arms.

Basics of Barbell Curls

Barbell curls are a type of arm curl that puts a lot of strain on the upper arms. In order to perform them safely and effectively, it is a good idea to have some basic knowledge. The following three items explain the basics of barbell curls.

• Parts trained with barbell curls
• The difference between barbell curls and dumbbell curls
• The difference between a straight bar and an EZ bar

Let's take a closer look at each one.

Basic knowledge 1: Parts trained by barbell curls

Barbell curls are a training method that mainly trains the biceps. The biceps are located on the front of the arm and consist of two muscles, the long head and the short head. The biceps are also known as the biceps, and training them makes the arms stronger.

Barbell curls put stress on the biceps and strengthen the bending and straightening of the arms. At the same time, they also train the brachialis and brachioradialis muscles, which has the effect of strengthening the entire upper arm.

The brachialis is located under the biceps and supports them, while the brachioradialis is located in the forearm and is an important muscle that improves lifting and grip strength. Barbell curls are a great way to train your biceps and make your upper arms bigger.

Basic knowledge 2: The difference between barbell curls and dumbbell curls

Barbell curls are a type of arm curl that trains the upper arms, and are very similar to dumbbell curls. Barbell curls and dumbbell curls are exercises that mainly train the biceps, but they each have different characteristics. Let's compare them in the table below.

Characteristic	Barbell curl	Dumbbell curl
Weight Adjustment	Can be safely subjected to high loads	Weight can be adjusted left and right
Range of motion	Limited range of motion	Wide range of motion
Muscle load	Focus on one large muscle group and apply high load	Allows stress across multiple muscle groups
Technical level	Easy to adopt even if you don't have technical skills	Requires proper form and technique
Recommended users	Beginners and those who want to increase their strength with a certain weight	For experienced users and those who want to train specific muscle groups evenly

Barbell curls allow you to train with particularly heavy weights and provide concentrated stimulation to your muscles with a stable form, while dumbbell curls have a wider range of motion and recruit more muscle groups, allowing you to build strength in a balanced way, but they require skill to be effective.

Understand the differences between the two and choose the training method that works best for you.

Basic knowledge 3: The difference between a straight bar and an EZ bar

Straight bars and EZ bars are two popular types of bars used for barbell curls, but they each have different characteristics. The table below compares the differences between the two bars.

Characteristic	Straight Bar	EZ Bar
shape	Linear	Wavy
Wrist strain	Relatively large	Relatively small
Effects on muscles	Strong stimulation to the long head of the biceps	Evenly stimulates not only the biceps but also the surrounding muscles
Recommended users	Those who value weight and want to make their upper arms look thicker	Those who want to train a wide range of muscles while avoiding strain on joints

Considering the characteristics of each bar, choose the appropriate equipment according to your training goals and personal physical condition to achieve more effective training.

Key points for barbell curls

When doing barbell curls, it is important to use the correct form and apply the appropriate load. Here are three points to increase the effectiveness of barbell curls:

• Set the right weight
• Set the appropriate number of repetitions and sets
• Follow the correct form and procedure

Let's take a closer look at each point.

Tip 1: Set the right weight

To achieve your ideal biceps with barbell curls, it's important to choose the right weight. If it's too light, you won't get the full effect, but if it's too heavy, your form will be compromised and you'll increase your risk of injury.

The key to determining the appropriate weight is to choose a weight that puts a moderate strain on your muscles while allowing you to exercise with proper form. It's a good idea to continue training and gradually increase the weight you can steadily lift.

Tip 2: Set the right number of repetitions and sets

To get the ideal upper arms with barbell curls, it is important to set the appropriate number of repetitions and sets. Beginners should start with 2-3 sets of 15 repetitions, and gradually increase the number of sets as they become comfortable.

In general muscle training, it is said that it is easier to build muscle if you use a load that allows you to do 10 repetitions, but since barbell curls tend to use weights that are too heavy, we recommend a load that allows you to do 15 repetitions. You will start to feel the strain after 10 repetitions, so it is a good idea to adjust the weight so that you reach your limit after 15 repetitions.

Tip 3: Use the correct form and procedure

Barbell curls are a basic weight training exercise that is most effective when performed with proper form.

1. Stand with your feet shoulder-width apart and knees slightly bent.
2. Grip the barbell at shoulder width, palms facing forward (hold with your hands facing away from you)
3. Arms fully extended, elbows at sides
4. Exhale as you slowly raise the barbell towards your chest, stopping at the top.
5. Inhale, keeping your muscles tense, and slowly return the barbell to the starting position.
6. Repeat steps 3 to 5

By following the basic steps to perform barbell curls, you can effectively target your biceps.

Barbell curl weight guideline

To maximize the effectiveness of barbell curls, you need to use the appropriate weight. The recommended weight will vary depending on your training experience and weight. We will explain the average recommended weight for barbell curls in the following three patterns.

• Beginner Male Weight
• Intermediate/Advanced Male
• woman

Let's take a closer look at the weight guidelines for each.

Weight guideline 1: Weight for beginner males

For men new to barbell curls, it is a good idea to start with 15kg, although this will vary depending on individual factors such as exercise experience and weight. If training with 15kg is difficult, you can reduce the load and start with 10kg. On the other hand, if you can lift 15kg easily or are somewhat accustomed to weight training, you can start with 20kg.

Once you get used to the training, gradually increase the load and aim for 20-30kg, which is an intermediate level. When beginners increase the weight, it is ideal to gradually adjust the weight in 2.5kg increments and progress while watching your body's reaction, rather than suddenly increasing the weight.

Weight guideline 2: Intermediate/Advanced Male

For intermediate and advanced men looking to take barbell curl training to a more advanced level, aim for 40% to 50% of your body weight, as this weight range is adequate to stimulate the muscles and promote further strength gains and hypertrophy.

For example, if your body weight is 80kg, the weight you should use for barbell curls should be between 32kg and 40kg. Even if you are training to build muscle, it is not necessarily better to use a heavier weight.

Even if the weight is heavy, if the load causes your form to deteriorate, the effect of muscle training will be reduced and it may be difficult to build muscle. We recommend a weight of 40% to 50% of your body weight as a range in which you can train without losing your form.

Weight guideline #3: Women

For women to effectively train with barbell curls, it is important to choose the right weight. In general, beginner women are recommended to start with a barbell of about 10 kg. If it is difficult to do so, use 10 kg as a standard, and if you have room, reduce the weight, and gradually increase it.

If you use the right weight, you can train safely because you can efficiently stimulate your muscles while maintaining the correct form. You can gradually increase the weight you can lift steadily, so make it a priority to maintain the correct form to increase the effect.

How to make barbell curls more effective

When doing barbell curls, using the correct form will increase the effectiveness of your training. Here are five ways to increase the effectiveness of barbell curls.

• Immobilize elbows and wrists
• Do not use recoil to lift
• Avoid arching your back
• Don't hold your breath
• Be aware of the muscles you are working

We will explain each method in detail.

Tip 1: Stabilize your elbows and wrists

To perform barbell curls effectively, it is important to fix your elbows and wrists in the correct position. Keep your elbows fixed at your sides and do not move back and forth during the movement, which will allow you to focus the load on your biceps. Keep your wrists firmly fixed without bending them inward as you lift the barbell.

If your wrists are not fixed, unnecessary strain may be applied and cause injury. Using wrist wraps is also effective for stabilizing your wrists. By being conscious of fixing your elbows and wrists, the weight of the barbell can be transmitted efficiently to your biceps, improving the effectiveness of your training.

Method 2: Don't use momentum to lift

To get the most out of barbell curls, it is important to directly load your muscles without using momentum. If you use momentum to lift the barbell, the load on your muscles will be reduced and the training effect will be reduced.

Training using momentum puts strain on joints and other muscles, which can increase the risk of injury. To work your muscles, perform the movements slowly and be aware of the strain on your muscles when lifting and lowering.

Tip 3: Avoid arching your back

When doing barbell curls, it is important to maintain good posture and not arch your back. Arching your back can put excessive stress on your lower back, which can lead to lower back pain.

Also, arching your back reduces the effect on your biceps, which are the muscles you are supposed to train, making it less effective training. To maintain proper form, it is important to be aware of your abdominal muscles and keep your back straight.

Tip 4: Don't hold your breath

It is important to be aware of not holding your breath when doing barbell curls. If you hold your breath during training, your body will not get enough oxygen, which will not only reduce your performance but also increase the risk of your blood pressure rising sharply.

Exhale when you lift the barbell and inhale when you lower it. Proper breathing optimizes the oxygen supply to your muscles, making your workout more effective.

Tip 5: Be aware of the muscles you are working

To accelerate muscle hypertrophy in the biceps with barbell curls, it is important to be aware of the muscles that are being worked during training. By feeling the contraction and stretching of the muscles, you can give a stronger stimulus to the muscles, improving the effectiveness of your training.

Make sure you feel the tension in your biceps when you lift the barbell, and the same muscles working properly when you lower it. By being aware of the muscles that are being worked, you can reduce unnecessary movement and concentrate the load on the target muscles, which will result in more effective training.

When to increase the weight of barbell curls

To improve your strength and build muscle with barbell curls, it is important to adjust the weight at the right time. In general, the time when you can stably do 3 sets of 10 repetitions is the time to increase the weight.

For example, if you can do 3 sets of 10 repetitions with your current weight, one way to do it is to increase the weight by about 5%. However, even if you cannot complete the number of sets with the increased weight, it is important not to force yourself to continue, but to gradually increase the weight until your muscles adapt. If increasing the weight causes your form to deteriorate, it increases the risk of injury, so prioritize safety and make appropriate weight adjustments.

Why barbell curls don't work

There's no need to rush into the results of your barbell curls, but if you think something is wrong, you should investigate. If you're continuing to do barbell curls but are not seeing results, try investigating the following four reasons.

• Reason #1: It’s not the right weight
• Reason #2: Not at the Right Frequency
• Reason #3: Poor nutrition
• Reason #4: You’re Too Urgent About Results

Let's take a closer look at each reason.

Reason #1: It’s not the right weight

If you are not getting results from barbell curls, there may be a problem with the weight setting. If the weight is too light, the muscles will not get the stimulation they need and will not grow. Conversely, if the weight is too heavy, your form will be compromised, increasing your risk of injury and preventing efficient muscle stimulation.

It is not enough to just make the weight heavier. Even if you use a load that you can steadily increase, the effect will be increased if you are conscious of stimulating the muscles. In order to maximize the effect of your training, it is important to determine the appropriate weight for you and review it regularly.

Reason #2: Not at the Right Frequency

You don't need to do muscle training every day. Training too frequently may actually reduce the effectiveness of your workouts.

According to the theory of "supercompensation," it takes 48 to 72 hours for muscles to recover after strength training, and training at the time of recovery is said to be more effective. By taking proper rest, muscles will grow more efficiently and get closer to your ideal body shape. If you are aiming for muscle hypertrophy, training 2 to 3 times a week is ideal.

Reason #3: Poor nutrition

Proper nutrition is important to increase muscle mass. Protein is a major component of muscle, and consuming sufficient amounts of it will enhance the effectiveness of muscle training. Ingesting high-quality protein from your diet on a daily basis is also essential for muscle growth.

Protein can be obtained from meat, fish, eggs, etc., but if it is difficult to ensure the necessary intake from food alone, it is a good idea to use protein powders. Protein powder is a concentrated source of high-quality protein, so it can be consumed efficiently. To increase the effectiveness of muscle training, you should also be aware of nutrition.

Reason #4: You’re Too Urgent About Results

Seeking immediate results can be an obstacle to continuing training. Generally, muscle changes become visible about three months after starting muscle training, but it is best to assume that it will take six months for others to notice the changes. Muscle hypertrophy is a gradual process that involves repeated supercompensation, which is the process by which muscles grow.

In the beginning of training, you may not be able to increase the weight or see any visible changes, but that doesn't mean it's ineffective. If you continue training steadily and correctly, your muscles will grow steadily and you will get closer to your ideal body shape.

We recommend using an EZ bar for barbell curls.

For barbell curls, we recommend using an EZ bar, which is designed to reduce strain on the wrists and elbows. The curved shape of the bar reduces stress on the joints and lowers the risk of injury during muscle training. Here we will explain in detail when to use an EZ bar and how to use it.

When to Use the EZ Bar

The EZ Bar is specifically designed to reduce strain on your wrists and elbows. The curved shape of the EZ Bar puts your wrists at a natural angle, which is less stressful than using a straight bar. This means you can safely handle the weight and still effectively work your biceps.

EZ bars are recommended for beginners and those with weak wrists because of their lightening properties, and are also suitable for those who want to develop muscles efficiently because the stable grip improves the quality of the workout.

How to use the EZ Bar

The method of arm curls using an EZ bar is almost the same as a regular barbell curl. It is easy to do because you hold the slanted part of the EZ bar. Once you have set the appropriate weight, follow the steps below to train.

1. Grab the EZ bar with your hands facing away from you and stand upright with your feet shoulder-width apart.
2. Keep your back straight and your chest slightly out
3. Keep your elbows close to your sides and prevent them from moving back and forth during the movement.
4. Bend your elbows to raise the EZ bar, then when you feel your biceps contract, slowly lower the bar.
5. Repeat steps 3 and 4.

Use the EZ bar to tone your upper arms while reducing strain on your wrists.
