Key points
- The preacher curl is a popular isolation exercise that primarily targets the biceps brachii muscle, with minimal involvement from the brachialis and brachioradialis.
- It’s named after the preacher curl machine, which helps isolate the biceps by providing a stable platform for your arm to rest on.

If you’re looking to build impressive biceps, the preacher curl is a must-have exercise in your arsenal. This isolation movement targets your biceps brachii muscle directly, allowing for maximum growth and definition. But mastering the technique is crucial to avoid injury and maximize results.

Understanding the Preacher Curl
The preacher curl is a popular isolation exercise that primarily targets the biceps brachii muscle, with minimal involvement from the brachialis and brachioradialis. It’s named after the preacher curl machine, which helps isolate the biceps by providing a stable platform for your arm to rest on. However, you can effectively perform preacher curls using dumbbells.
Benefits of Preacher Curls
- Isolated Bicep Growth: The preacher curl isolates the biceps, allowing you to focus on maximizing muscle activation and growth.
- Enhanced Strength: This exercise helps build strength and power in your biceps, which translates to increased lifting capability in other exercises.
- Improved Definition: The preacher curl helps sculpt and define your biceps, giving them a more pronounced and aesthetically pleasing appearance.
- Reduced Injury Risk: By isolating the biceps, the preacher curl can help minimize strain on your wrists and elbows compared to other bicep exercises.
Setting Up for Success
Before you start, ensure you have the right equipment and setup:
- Dumbbell: Choose a weight that challenges you but allows you to maintain good form throughout the exercise.
- Preacher Bench: While not mandatory, a preacher bench provides stability and support, making it easier to maintain proper form.
- Grip: Use a supinated grip (palms facing up) for the standard preacher curl.
Step-by-Step Guide to Preacher Curls with Dumbbells
1. Position Yourself: Sit on the preacher bench with your chest against the pad. Ensure your upper arm is firmly against the pad, and your elbow is slightly bent.
2. Grip the Dumbbell: Hold the dumbbell with a supinated grip, keeping your palms facing upwards.
3. Starting Position: Lower the dumbbell slowly until your arm is fully extended and your bicep is stretched.
4. The Curl: Keeping your upper arm stationary, curl the dumbbell upwards, engaging your biceps. Focus on squeezing the bicep at the top of the movement.
5. Controlled Descent: Slowly lower the dumbbell back to the starting position, maintaining control throughout the movement.
6. Repetitions: Perform the desired number of repetitions, focusing on maintaining proper form throughout.
Common Mistakes to Avoid
- Swinging: Avoid using momentum to lift the weight. Focus on controlled, deliberate movements.
- Rounded Back: Keep your back straight and your shoulders relaxed. Avoid rounding your back, which can put strain on your lower back.
- Jerky Movements: Smooth, controlled movements are key to maximizing muscle activation and preventing injury.
- Overextending the Elbow: Do not fully lock your elbow at the bottom of the movement. Maintain a slight bend to protect your joint.
- Using Too Much Weight: Choosing a weight that is too heavy can compromise your form and increase the risk of injury.
Preacher Curl Variations
- Close Grip Preacher Curl: Use a narrower grip to target the inner portion of your biceps.
- Hammer Preacher Curl: Hold the dumbbell with a neutral grip (palms facing each other) to engage the brachioradialis muscle in your forearm.
- Reverse Preacher Curl: Use a pronated grip (palms facing down) to target the brachialis muscle.
- Preacher Curl with Cable Machine: Use a cable machine for a constant tension preacher curl, which can be more challenging than using dumbbells.
Tips for Maximizing Your Preacher Curls
- Focus on Form: Prioritize proper form over lifting heavy weights.
- Mind-Muscle Connection: Concentrate on engaging your biceps throughout the movement.
- Progressive Overload: Gradually increase the weight or repetitions over time to challenge your muscles.
- Rest and Recovery: Allow your muscles adequate time to rest and recover between workouts.
- Vary Your Workout Routine: Incorporate different preacher curl variations to target your biceps from various angles.
