What To Know
- The preacher curl, a staple exercise in any arm workout regimen, is designed to primarily target the biceps brachii muscle.
- This exercise is performed by sitting on a preacher curl bench, placing the upper arms on the angled pad, and curling a barbell or dumbbells towards the shoulders.

The preacher curl, a staple exercise in any arm workout regimen, is designed to primarily target the biceps brachii muscle. This exercise is performed by sitting on a preacher curl bench, placing the upper arms on the angled pad, and curling a barbell or dumbbells towards the shoulders.
Primary Target Muscle: Biceps Brachii
The biceps brachii is a two-headed muscle located on the front of the upper arm. It is responsible for flexing the elbow joint and supinating the forearm. The preacher curl effectively isolates the biceps brachii, allowing for focused development and strength gains.
Secondary Target Muscles:
While the biceps brachii is the primary muscle worked by the preacher curl, several other muscles also play a supporting role:
Brachioradialis:
The brachioradialis is a forearm muscle that assists in flexing the forearm.
Brachialis:
The brachialis is located beneath the biceps and contributes to elbow flexion.
Supinator:
The supinator is a forearm muscle that supinates the forearm, rotating it palm up.
Variations of the Preacher Curl:
Barbell Preacher Curl:
This variation uses a barbell to provide resistance. It allows for heavy weightlifting and progressive overload.
Dumbbell Preacher Curl:
Using dumbbells in the preacher curl allows for unilateral training, targeting each arm independently.
Cable Preacher Curl:
This variation uses a cable machine, providing constant tension throughout the movement.
Reverse Preacher Curl:
This variation targets the brachialis and supinator muscles by curling the bar or dumbbells towards the forehead.
Benefits of the Preacher Curl:
Increased Biceps Mass:
The preacher curl effectively isolates the biceps, promoting muscle growth and hypertrophy.
Enhanced Biceps Strength:
Regular preacher curls can significantly improve elbow flexion strength, beneficial for various athletic activities.
Improved Forearm Strength:
The involvement of secondary forearm muscles during the preacher curl strengthens the forearms, enhancing grip strength.
Reduced Elbow Pain:
By strengthening the biceps, the preacher curl can help reduce elbow pain caused by weak or overused muscles.
Proper Form for the Preacher Curl:
1. Sit on the preacher curl bench with your chest against the pad.
2. Place your elbows on the pad, shoulder-width apart.
3. Grip the bar or dumbbells with a supinated grip (palms facing up).
4. Curl the weight towards your shoulders, keeping your upper arms stationary.
5. Slowly lower the weight back to the starting position.
Tips for Maximizing Results:
Use Proper Weight:
Choose a weight that challenges you while maintaining good form.
Focus on the Biceps:
Concentrate on engaging the biceps throughout the movement.
Control the Movement:
Avoid using momentum to swing the weight. Instead, focus on smooth, controlled repetitions.
Train to Failure:
Push yourself to the point of momentary muscle failure to maximize muscle fiber activation.
Rest Adequately:
Allow sufficient rest time between sets to allow for muscle recovery.
Takeaways: Unlocking the Power of the Preacher Curl
The preacher curl is an effective exercise for targeting the biceps brachii muscle, promoting muscle growth, strength, and overall arm development. By incorporating proper form, variations, and training principles, you can maximize the benefits of this exercise and achieve your fitness goals.
