Bicep curls are an exercise that almost every lifter does. Newbies to advanced lifters all know how to work those biceps. There's arguably no more satisfying muscle to train. Preacher curls are a staple arm day training exercise to build bigger stronger biceps. What’s great about the preacher curl, is the isolation, which can focus more direct muscle activation on the biceps, for a more defined and stronger physique. We would dive into the world of the preacher curls, including the benefits, workout form, and variations
What is a preacher curl?
A preacher curl is a strength-training exercise that targets the muscles of the upper arm, specifically the biceps. It is commonly performed using a preacher curl bench or a preacher curl attachment on a weight bench or gym equipment.
Preacher curls are particularly effective at isolating the biceps muscles because they minimize the involvement of other muscle groups, such as the shoulders and back. The preacher curl is performed with a bench that is designed for you to sit down with your upper arms resting on a surface that is slightly tilted inwards. This biceps curl variation allows you to hone in on the biceps while not using any other part of your body, you can maintain strict form and concentrate on fully engaging and targeting the biceps throughout the exercise.
Why do preacher curl?
Preacher curls are a popular exercise primarily targeting the biceps muscles. They involve performing curls while resting your upper arms on a preacher curl bench or pad, which isolates the biceps and reduces the involvement of other muscles. Its main benefit is straightforward as well: bigger biceps.Biceps isolation: Preacher curls specifically target the biceps muscles, allowing you to place greater emphasis on them compared to other compound exercises like barbell curls or chin-ups. This isolation can help in developing stronger and more defined biceps.
Improved arm strength: Preacher curls primarily focus on the biceps brachii, the main muscle responsible for elbow flexion. By regularly performing this exercise, you can develop stronger biceps, which can contribute to overall arm strength and functionality.
Joint stability: Preacher curls provide a stable and controlled environment for performing the exercise. By keeping your upper arms supported on the bench, you reduce the involvement of other muscles and stabilize the elbow joint, minimizing the risk of swinging or using momentum to lift the weight. This can help prevent cheating and promote better form and technique.
How to do preacher curl with the correct form
While the movement itself is relatively straightforward, one drawback of the preacher curl is its reliance on a specific piece of equipment called a preacher bench. However, most well-equipped gyms should have one, and if you have a comprehensive home gym setup, you can also consider adding a preacher bench to your collection. The preacher bench is designed in a way that positions your arms on a sloping surface, providing support for the upper arm."
"There are five primary variations of the preacher curl that you can incorporate into your workout routine: utilizing an EZ bar, dumbbells, kettlebells, barbells, or resistance bands.
It's important to note that when performing the preacher curl, you'll typically work with lighter weights compared to traditional curls. This is due to the preacher curl's ability to place you in a less stable position, emphasizing controlled movements and preventing cheating with momentum. The focus on maintaining proper form and activating the target muscles more
effectively will lead to earlier fatigue in your arms, making it preferable to use less weight. That's why it's beneficial to view the preacher curl as a supplementary exercise to your regular biceps curl routine, rather than a replacement. By incorporating the preacher curl, you can introduce some variation into your arm training regimen.
Set up the equipment: Position a preacher curl bench or pad in front of a preacher curl station or use a preacher curl attachment on a weight bench. Adjust the height of the bench or pad so that your arms are fully extended when gripping the barbell or dumbbells. Sit on the preacher curl bench with your chest pressing against the pad and your feet flat on the floor. Ensure that your upper arms rest comfortably on the pad, just above your elbows.
Grip the bar: Grasp the barbell or dumbbells with an underhand grip (palms facing upward) and hands shoulder-width apart. Your grip should be firm but not excessively tight.
Position your body: Maintain an upright posture with your shoulders back and your core engaged. This helps stabilize your upper body throughout the movement.
Execute the curl: While keeping your upper arms in contact with the pad, exhale and slowly curl the weight upward by flexing your elbows. Focus on contracting your biceps muscles fully and avoid using excessive momentum or swinging. Pause briefly at the top of the movement when your biceps are fully contracted. Squeeze your biceps for a more intense contraction.
Lower the weight: Inhale and slowly lower the weight back down to the starting position, extending your arms fully. Maintain control throughout the eccentric (lowering) phase of the exercise.
Common tips for preacher curls:
Start with a weight that allows you to maintain proper form and complete the desired number of repetitions.
Warm up adequately to prepare your muscles and joints for the exercise.
Focus on the mind-muscle connection, consciously contracting and engaging your biceps throughout the movement.
Gradually increase the weight as you progress to continue challenging your muscles.
Common mistakes to avoid:
Using excessive weight: Prioritize using a weight that allows you to maintain proper form and control throughout the exercise. Using too much weight can lead to poor technique and increase the risk of injury.
Cheating with momentum: Avoid swinging your body or using momentum to lift the weight. The emphasis should be on controlled, slow, and deliberate movements.
Allowing the shoulders to round forward: Keep your shoulders back and maintain good posture throughout the exercise. Rounding the shoulders can lead to improper form and take the emphasis away from the biceps.
Lifting the elbows off the pad: Ensure that your upper arms remain in contact with the pad throughout the movement. Lifting the elbows off the pad reduces the isolation of the biceps and can lead to strain on the wrists and forearms.Remember to consult with a fitness professional or trainer if you are new to preacher curls or weightlifting in general to ensure proper form and technique.
What muscle works?
The preacher curl primarily targets and works the muscles in the upper arm, specifically the biceps brachii muscle group. Here are the main muscles involved in the preacher curl:
Biceps Brachii: The biceps brachii is the main muscle targeted during the preacher curl exercise. It is composed of two heads (long head and short head) and is responsible for flexing the elbow joint, bringing the forearm closer to the upper arm.
Brachialis: The brachialis is a muscle located underneath the biceps brachii. It lies deep to the biceps and is also involved in elbow flexion. By performing preacher curls, you can effectively engage and develop the brachialis muscle.
Brachioradialis: The brachioradialis is a forearm muscle that runs along the outer side of the forearm. Although it is not the primary target of the preacher curl, it acts as a synergist muscle, assisting the biceps in elbow flexion during the exercise.
Other muscles, such as the forearm flexors and stabilizer muscles, are also engaged to a lesser extent during the preacher curl exercise. These include the pronator teres, flexor carpi radialis, and flexor carpi ulnaris, which help stabilize the wrist and forearm during the movement.
By incorporating the preacher curl into your workout routine, you can specifically target and strengthen the muscles of the upper arm, particularly the biceps brachii, leading to improved muscle development, strength, and overall arm aesthetics.
Preacher curl variations
DUMBBELL PREACHER CURLS: The execution of the dumbbell preacher curl follows the same principles as the EZ bar preacher curl, engaging the same muscle groups from a comparable angle. However, the key distinction lies in the use of individual dumbbells, which enhances unilateral strength and highlights any potential strength imbalances between your sides.
By performing the dumbbell preacher curl, you not only stimulate the targeted muscles in a focused manner, but you also address any asymmetries in strength or development between your left and right arms. Lifting separate dumbbells forces each arm to work independently, requiring greater stability and coordination. This unilateral approach encourages equal muscle activation and helps rectify any discrepancies in strength or muscular development.
BARBELL PREACHER CURL: Performing barbell curls on a preacher bench shares many similarities with the EZ curl bar variation, but there is one crucial distinction to consider. The EZ curl bar, with its unique wavy design, offers a slightly easier grip and places less strain on the elbows. However, if your elbows are in good condition, opting for the barbell variation allows you to handle heavier weights and potentially achieve greater strength gains. Additionally, performing barbell curls on a preacher bench can help minimize the temptation to resort to cheat curls, a common occurrence with standing barbell curls (though cheat curls aren't always detrimental to your progress).
By choosing the barbell preacher curl, you can challenge your biceps with heavier loads and potentially stimulate greater muscle growth and strength development. This variation also provides a more stable and controlled environment, promoting strict form and discouraging excessive body movement. While cheat curls can have their place in training, utilizing the barbell preacher curl enables a more targeted focus on the biceps while minimizing the reliance on momentum.
Ultimately, the choice between the EZ curl bar and barbell preacher curl depends on factors such as your elbow health, grip preferences, and specific training goals. Experimenting with both variations can help you determine which option suits your needs best and optimizes your biceps training.
CLOSE GRIP PREACHER CURL:The close grip preacher curl provides you with various choices for equipment selection. This exercise can be executed using dumbbells, an EZ curl bar, or a barbell. Each option has its merits, and the choice depends on your personal preference and how well your joints respond to the specific equipment used.
Engaging in the close grip preacher curl allows you to emphasize the long head of the biceps muscle. By adopting a narrower handgrip, the tension is strategically redirected towards the outer fibers of the biceps. This targeted focus on the outer bicep muscle fibers helps promote balanced development and enhances the overall aesthetics of your arms.
When deciding between the different equipment options, consider factors such as comfort, grip variation, and any joint sensitivities you may have. Experimenting with dumbbells, an EZ curl bar, or a barbell can help you determine which equipment feels most effective and suits your individual needs. Focus on maintaining a controlled and deliberate movement throughout the exercise, ensuring that your biceps are effectively engaged and experiencing the desired tension.
DUMBBELL HAMMER PREACHER CURLS: The dumbbell hammer preacher curl provides several advantages due to the neutral wrist position, benefiting you in multiple ways. Here's how:
Strongest Grip: The neutral grip in the dumbbell hammer preacher curl is considered the strongest grip for many individuals. This advantageous grip allows you to perform more repetitions with increased ease, ultimately enhancing your endurance during the exercise.
Joint-Friendly Position: By utilizing the neutral wrist position, your joints are neither externally nor internally rotated. This alignment contributes to reduced stress on your wrist, elbow, and shoulder joints, making the exercise more comfortable and decreasing the risk of joint discomfort or injury.
Emphasis on Brachioradialis and Brachialis: The hammer grip primarily targets the brachioradialis and brachialis muscles, in addition to the biceps. The brachioradialis is located on the outer side of the forearm, while the brachialis lies underneath the biceps. By placing greater emphasis on these muscles, the dumbbell hammer preacher curl contributes to well-rounded upper arm development, resulting in improved aesthetics and overall strength.
Incorporating the dumbbell hammer preacher curl into your arm training routine allows you to leverage the benefits of a neutral grip, promoting stronger and more resilient joints while effectively targeting the brachioradialis, brachialis, and biceps muscles.
REVERSE PREACHER CURL:The reverse grip preacher curl is a valuable exercise that specifically targets the forearm extensors, a muscle group that is often overlooked. By utilizing an overhand grip during the reverse curl, you engage and train these essential muscles, offering two significant benefits:
Improved Forearm Development: The reverse grip places a greater emphasis on the forearm extensors, aiding in their targeted development. These muscles are responsible for extending the wrist and fingers, and by giving them due attention, you can enhance forearm size, strength, and overall muscularity.
Enhanced Joint Health: Balancing the strength between the flexors (forearm muscles involved in wrist and finger flexion) and extensors is crucial for optimal joint health, particularly in the elbows. The reverse grip preacher curl helps achieve this balance by actively engaging the forearm extensors, which are often neglected in traditional biceps exercises. This balance can lead to healthier elbows, reducing the risk of imbalances and related injuries.
