For arm workouts, I believe that all men will not refuse. Strong arms give people a very strong sense of security, and in summer, wearing short sleeves can also see their strong muscles, a man’s best vanity was satisfied.

Barbell curls are one of the classic and most effective exercises for building massive biceps. Many people still understand it, but many people don’t know where the barbell curl exercise is, what are the benefits, and how to do barbell curl. Let's learn more about it!

What muscles do barbell curls train?

 

 

barbell curl muscles worked

 

Barbell curls primarily target the muscles of the upper arm, specifically the biceps brachii. The biceps brachii is a two-headed muscle located on the front of the upper arm. It consists of a long head and a short head, both of which are engaged during barbell curls.

While the biceps brachii is the primary muscle worked during barbell curls, several other muscles act as synergists or stabilizers during the exercise. These include:

Brachialis: Located underneath the biceps brachii, the brachialis muscle assists in elbow flexion and contributes to the overall size and definition of the upper arm.

Brachioradialis: Situated on the forearm, the brachioradialis helps stabilize the elbow joint during the curling motion. It also assists in elbow flexion and plays a secondary role in the movement.

Forearm muscles: Various muscles in the forearm, such as the flexor carpi radialis and flexor carpi ulnaris, are activated to a lesser extent during barbell curls. They assist in wrist stabilization and contribute to grip strength.

It's important to note that while barbell curls primarily target the muscles mentioned above, they can also engage other muscles to a lesser degree, such as the deltoids (shoulders) and the muscles of the upper back and core, as they help stabilize the body during the exercise.

 

Benefits of the Barbell Curl

1.Increase upper body weight

But it’s great if you can fill your shirt. If this is your goal, a barbell curl will help. Any time you put pressure on your muscles, it will respond and make you bigger and stronger again. (Assuming that your macro is called and you eat right. Diet is the key.) Although biceps are the muscles you want to exercise and should be exercised in this exercise, your chest, shoulders, and trapezius muscles will even Enter to play a little bit.

In addition, barbell curls can bear heavier weight than other curl exercises. This means you can load your muscles faster and last longer without reaching a plateau.

2.Improve grip

Barbell curls can help improve grip and arm strength, both of which affect tension and performance. Your biceps are moving weight, but your hands, wrists, and forearms support it. All these secondary muscles will be affected, so your grip will be poor.

3.Injury prevention (elbow/arm)

The biceps are responsible for elbow flexion and support the grip muscles in tension and load handling. Weak and underdeveloped biceps can cause grip problems, biceps strain, and in some cases, muscle tears. Stronger biceps are more elastic biceps. Hey, not all benefits are related to padded shirts.

4.They’re accessible

Whether you own a barbell set, a pair of adjustable dumbbells, or even a quality kettlebell— you can curl! You don’t need to haul a cable machine into your home gym to build a set of Larry Scott-like sleeve-huggers. You can do barbell curls in about a square foot if you needed to. They’re simple and easy to execute.

How to do barbell curls?

1.Action preparation

Practitioners generally stand with feet shoulder-width apart, hold the barbell with both sides of the body with both hands, hold the barbell in front of the body, and use a wide grip (or a narrow grip) for the grip of the barbell.

2.Movement process

The practitioner concentrates the strength of the biceps of the arm to quickly lift the barbell to the position of the clavicle of the neck, then pauses for a while, and then uses the strength of the biceps of the arm to control the barbell to slowly return to the starting position. It is generally recommended that during the barbell curling action, the upward lift is controlled for 1 second, the pause is 1 second, and the recovery is 3 seconds.

3.Action requirements

Practitioners must stand tall and tighten their waist and abdomen during the movement.

The practitioner must clamp both sides of the body with his hands during the movement.

The practitioner exhales when exerting upward force during the movement, and inhales when restoring.

Barbell curls common mistakes

1.Do not pay attention to eccentric training

Many people know how to do barbell curls. After arm curls, you can restore them to complete an action. However, the eccentric training that many people ignore is always fast and release. The number of times that can be done without controlling eccentric training is very high. Many, but a single stimulation of the muscles will be reduced a lot.

The practice of eccentric training is to slowly lower the muscles when the muscles reach the peak contraction and keep the lowering time within 2-4 seconds, which helps to increase the muscles.

2.The action is not complete

I believe that everyone has seen some people doing barbell curls in the gym, but many people did not start to lower their arms parallel to the ground. The reason is that the selected weight is too heavy, which causes the movement to deform, so there is no complete training. , The muscles cannot reach the peak contraction, the growth rate of the muscles will slow down, and the biceps will not be fully trained.

3.The torso is not fixed

Many people have an inertial movement when doing barbell curls, that is, the body follows the arm to swing. This is not good because the body has borrowed force, which reduces the force of the arm. If the body cannot maintain integrity The posture, then, will slow down the muscle exertion, and it will also cause waist injury.

4.The range of motion is different each time

When many people perform barbell curls, the action process is different each time. Such training has very low performance for training, and the training efficiency is also very low.

The reason is that each time the training range is different, it leads to different muscle feelings, resulting in uneven force.

5.Leverage

Almost more than 90% of people will have leverage when doing barbell curls. Whether it is shaking back and forth, using leverage, or using the arm, it will cause inefficiency in training.

5 Barbell Curl Variations

To keep your arm workouts challenging and engaging, you can explore several barbell curl variations:

E-Z Curl Bar Curls

E-Z Curl Bar Curls

 

These are similar to standard barbell curls but performed with an E-Z curl bar, which can be easier on the wrists.

  1. Start by standing upright with your feet shoulder-width apart. Grab the E-Z curl bar with an underhand grip (palms facing upward) at a comfortable width, usually slightly narrower than shoulder-width apart.
  2. Allow your arms to fully extend, with the bar resting against your thighs. Keep your elbows close to your sides throughout the exercise.
  3. Engage your core and maintain a neutral spine. This will help stabilize your body and prevent excessive swinging or leaning.
  4. Initiate the movement by flexing your elbows and curling the barbell upward towards your shoulders. Keep your upper arms stationary and avoid using momentum to lift the weight.
  5. Continue lifting until your biceps are fully contracted and the bar is close to your shoulders. Squeeze your biceps at the top of the movement to maximize the contraction.
  6. Pause briefly at the top of the curl, then slowly lower the barbell back down to the starting position in a controlled manner. Fully extend your arms, but maintain tension on the biceps throughout the descent.

    Preacher Curls

    Preacher Curls

     

    Preacher curls are a great exercise for targeting the biceps and building upper arm strength. They are typically performed using a preacher curl bench or an adjustable bench set to a slight incline.

    1. Adjust the preacher curl bench or the adjustable bench to a comfortable height. Sit down on the bench and position yourself so that your upper arms rest flat against the angled pad, and your chest is pressed against it.
    2. Grab an E-Z curl bar with an underhand grip (palms facing upward) at shoulder-width apart. Your arms should be fully extended, and your hands should be positioned just outside shoulder-width.
    3. Keep your feet flat on the floor for stability and maintain a neutral spine throughout the exercise.
    4. Initiate the movement by flexing your elbows and curling the barbell or dumbbells upward. As you curl, focus on contracting your biceps and avoid using momentum or swinging to lift the weight. Keep your upper arms pressed against the pad throughout the exercise.
    5. Continue lifting until your biceps are fully contracted, and the barbell or dumbbells are close to your shoulders. Squeeze your biceps at the top of the movement to maximize the contraction.

      Wide-Grip Barbell Curl

      Wide-Grip Barbell Curl

      Wide-grip barbell curls, also known as wide-grip bicep curls, are a variation of the barbell curl exercise that targets the biceps brachii muscles from a different angle by using a wider grip. 

      1. Stand upright with your feet shoulder-width apart and grab the barbell with an underhand grip (palms facing upward) that is wider than shoulder-width apart. Your hands should be positioned on the barbell outside of your shoulders.
      2. Allow your arms to fully extend, letting the barbell rest against your thighs. Keep your elbows close to your sides throughout the exercise.
      3. Engage your core and maintain a neutral spine for stability during the movement.
      4. Initiate the exercise by flexing your elbows and curling the barbell upward. As you curl, keep your upper arms stationary and avoid using momentum or swinging to lift the weight. Focus on contracting your biceps.
      5. Continue lifting until your biceps are fully contracted, and the barbell is close to your shoulders. Squeeze your biceps at the top of the movement to maximize the contraction.

      Close-Grip Barbell Curl

      Close-Grip Barbell Curl

       

      Take a narrower grip on the barbell, with your hands positioned closer together. This variation places more emphasis on the long head of the biceps and can help develop the peak of the biceps.

      1. Stand upright with your feet shoulder-width apart and grab the barbell with an underhand grip (palms facing upward) that is closer than shoulder-width apart. Your hands should be positioned on the barbell inside of your shoulders.
      2. Allow your arms to fully extend, letting the barbell rest against your thighs. Keep your elbows close to your sides throughout the exercise.
      3. Engage your core and maintain a neutral spine for stability during the movement.
      4. Initiate the exercise by flexing your elbows and curling the barbell upward. As you curl, keep your upper arms stationary and avoid using momentum or swinging to lift the weight. Focus on contracting your biceps.
      5. Continue lifting until your biceps are fully contracted, and the barbell is close to your shoulders. Squeeze your biceps at the top of the movement to maximize the contraction.

      Reverse-Grip Barbell Curl

      Reverse-Grip Barbell Curl

       

      Reverse-grip barbell curls, also known as supinated grip barbell curls, are a variation of the barbell curl exercise where you use an overhand grip (palms facing downward) instead of the traditional underhand grip.

      1. Stand upright with your feet shoulder-width apart and hold the barbell with an overhand grip (palms facing downward) that is slightly narrower than shoulder-width apart. Your hands should be positioned on the barbell outside of your thighs.
      2. Allow your arms to fully extend, with the barbell resting against your thighs. Keep your elbows close to your sides throughout the exercise.
      3. Engage your core and maintain a neutral spine for stability.
      4. Initiate the exercise by flexing your elbows and curling the barbell upward. As you curl, keep your upper arms stationary and avoid using momentum or swinging to lift the weight. Focus on contracting your biceps and brachialis.
      5. Continue lifting until your biceps are fully contracted, and the barbell is close to your shoulders. Squeeze your biceps and brachialis at the top of the movement to maximize the contraction.

        Conclusion

        Barbell curls are a cornerstone of arm training and can lead to substantial biceps development when performed with proper form and consistency. Whether you're a beginner or a seasoned lifter, these exercises offer a multitude of benefits, from bigger biceps to improved functional strength. By exploring different variations and applying advanced training techniques, you can take your arm gains to new heights and confidently show off those powerful guns.
