What To Know
- The preacher curl is a popular isolation exercise that targets the biceps brachii, the primary muscle responsible for flexing the elbow.
- The preacher curl emphasizes the long head of the biceps, which is responsible for the peak of the bicep.

Are you looking to build bigger, stronger biceps? Then you’ve probably come across the preacher curl and the concentration curl. Both exercises target the biceps brachii, but they do so in slightly different ways. This leads to the question: which one is better?
In this blog post, we’ll dive deep into the preacher curl vs concentration curl debate. We’ll break down the mechanics of each exercise, explore their pros and cons, and ultimately help you determine which one is the right fit for your fitness goals.
Understanding the Preacher Curl
The preacher curl is a popular isolation exercise that targets the biceps brachii, the primary muscle responsible for flexing the elbow. It’s often performed on a preacher curl machine, but can also be done using a dumbbell or barbell.
How to Perform a Preacher Curl:
1. Set Up: Sit on the preacher curl machine with your upper arms resting on the pad. Your elbows should be slightly bent.
2. Grip: Grasp the curl bar with an underhand grip, slightly wider than shoulder-width apart.
3. Execution: Curl the bar up towards your shoulders, keeping your elbows fixed. Slowly lower the bar back to the starting position.
Benefits of the Preacher Curl:
- Increased Biceps Isolation: The preacher curl machine helps isolate the biceps by preventing momentum and cheating.
- Improved Mind-Muscle Connection: The fixed position allows you to focus on the contraction of your biceps.
- Enhanced Range of Motion: The preacher curl allows for a full range of motion, which can help to stimulate muscle growth.
Drawbacks of the Preacher Curl:
- Potential for Shoulder Strain: The fixed position can put stress on your shoulders, especially if you use heavy weights.
- Limited Flexibility: The machine can restrict your movement, making it difficult to adjust your grip or range of motion.
Understanding the Concentration Curl
The concentration curl is another popular isolation exercise that targets the biceps brachii. It’s typically performed while seated on a bench with your elbow resting on the inside of your thigh.
How to Perform a Concentration Curl:
1. Set Up: Sit on a bench with your feet flat on the floor. Rest your elbow on the inside of your thigh, with your upper arm close to your body.
2. Grip: Hold a dumbbell in your hand with an underhand grip.
3. Execution: Curl the dumbbell up towards your shoulder, keeping your elbow fixed. Slowly lower the dumbbell back to the starting position.
Benefits of the Concentration Curl:
- Improved Focus: The concentration curl forces you to focus on your biceps and prevents cheating by using momentum.
- Enhanced Control: The seated position allows for better control of the movement, which can help to prevent injury.
- Versatile Exercise: It can be performed with dumbbells, barbells, or resistance bands.
Drawbacks of the Concentration Curl:
- Limited Weight: The seated position can limit the amount of weight you can lift.
- Potential for Elbow Strain: If your form is incorrect, you could put strain on your elbow joint.

- Targeting the Short Head of the Biceps: The concentration curl emphasizes the short head of the biceps, which is responsible for the lower portion of the bicep.
- Adding Variety to Your Routine: The concentration curl provides a different angle of attack on the biceps, which can help to stimulate muscle growth.
Final Thoughts: Finding Your Perfect Bicep Builder
Ultimately, the best exercise for you will depend on your individual goals, preferences, and physical limitations. If you’re looking to build mass and improve your mind-muscle connection, the preacher curl is a great option. If you’re looking for a more controlled exercise with a focus on the short head of the biceps, the concentration curl is a better choice.
