8+ Preacher Curls: Muscles Targeted & More

The preacher curl, a popular isolation exercise, primarily develops the brachialis muscle located deep within the upper arm, beneath the biceps brachii. It also engages the biceps brachii and brachioradialis, contributing to overall arm strength and size. Performing this exercise involves flexing the elbow joint while the upper arm is stabilized against a sloped pad, resembling a preacher’s pulpit.

Developing the brachialis offers several advantages. A stronger brachialis contributes significantly to elbow flexion strength, important for various pushing and pulling movements. Its development also pushes the biceps upwards, creating a more prominent “peak” often desired by bodybuilders. Historically, the preacher curl has been a staple in bodybuilding routines for this reason. A well-developed brachialis can enhance overall arm aesthetics and functional strength.

The preacher curl, a popular isolation exercise, primarily develops the brachialis muscle, located deep beneath the biceps brachii. It also engages the biceps brachii and brachioradialis, contributing to overall arm strength and size. The distinct positioning on a preacher bench isolates the brachialis, promoting focused growth and strength development. By minimizing involvement of other muscles, the exercise delivers concentrated resistance to this often-undertrained muscle.

A well-developed brachialis contributes significantly to overall arm aesthetics and functional strength. Because it sits beneath the biceps, a larger brachialis pushes the biceps upwards, enhancing the “peak” and creating a more impressive arm profile. Beyond aesthetics, the brachialis plays a vital role in elbow flexion, crucial for everyday activities and various sports. Historically, preacher curls have been a cornerstone exercise in bodybuilding and strength training regimens, recognized for their effectiveness in isolating and developing the brachialis.
