Barbell Preacher Curl
The barbell preacher curl is an isolation exercise designed to strictly target the biceps brachii by immobilizing the upper arms against an angled pad. It is particularly effective for building upper arm mass and peak development, making it an excellent addition to the middle or end of an arm workout.
How to do it
- Sit at a preacher bench with your upper arms resting on the pad, holding a barbell with an underhand grip.
- Your feet should be flat on the floor, and the upper arms should be fully extended along the pad.
- Inhale and brace your core. Curl the barbell towards your shoulders, keeping your upper arms stationary on the pad.
- Lift the barbell until your biceps are fully contracted.
- Exhale as you slowly lower the barbell back to the starting position, maintaining control and keeping your upper arms on the pad.
Common mistakes
- Fully locking out and hyperextending the elbows at the bottom places dangerous mechanical stress on the bicep tendons.
- Lifting the elbows or chest off the pad during the curl recruits the anterior deltoids and robs the biceps of tension.
- Leaning back to swing the barbell upward eliminates the strict isolation that the preacher bench is meant to enforce.
Tips
- Stop just short of full elbow extension at the bottom of each rep to keep tension continuous and protect your joints.
- Use an EZ-curl bar instead of a straight barbell to alleviate strain on your wrists and forearms.
- Take two to three seconds to lower the bar under full control to take advantage of the eccentric phase.
Sets and reps
For hypertrophy, perform 3 to 4 sets of 8 to 12 repetitions with 60 to 90 seconds of rest between sets. Avoid heavy, low-rep training on this exercise because the extended elbow angle leaves the bicep tendons vulnerable under extreme loads.

Questions
What is the main benefit of preacher curls over regular standing curls?
The preacher bench completely prevents swinging and shoulder involvement, forcing the biceps to do all the work from a stretched position.
What should you do if you experience pain in your elbows during the movement?
Sharp or persistent elbow pain indicates excessive tendon strain, so stop the exercise immediately and consult a healthcare specialist if it does not resolve.
