Biomechanical cues verified by the PlanWorkouts Science Review Board under CSCS editorial oversight; see our editorial standards.
The Barbell Lying Preacher Curl is a targeted isolation upper arms movement designed to train the Biceps.
Single-joint elbow flexion isolated in the sagittal plane. Focuses mechanical load on biceps brachii (long and short heads) and brachialis with minimal torso swinging. Executing this with strict form maximizes muscle fiber recruitment while protecting joint structures.
Quick Exercise Facts
Target Muscle Activation
The lying preacher curl braces the arms against an inclined surface while lying down, which locks out the shoulders even more strictly than a standard preacher bench does. That removes essentially all momentum from the lift, leaving the biceps with nowhere to hide. It's a strict isolation option for lifters who find their curls sneaking in shoulder movement even on a regular preacher bench.
How to Do the Barbell Lying Preacher Curl
- Sit at a preacher bench with your chest against the pad and your arms extended over the edge, gripping a barbell underhand.
- With your upper arms still, exhale as you curl the bar upward, contracting your biceps.
- Keep raising the bar until your biceps are fully contracted and it reaches shoulder height.
- Pause briefly in the contracted position, squeezing your biceps.
- Inhale as you slowly lower the barbell back to the starting position.
- Continue for the prescribed repetitions while maintaining full control through both the lift and lower phases.

Biomechanical & Joint Load Cues
Single-joint elbow flexion isolated in the sagittal plane. Focuses mechanical load on biceps brachii (long and short heads) and brachialis with minimal torso swinging.
Common Mechanical Mistakes & Form Errors to Avoid
- Swinging Hips & Lower Back: Using momentum from the hips to swing the weight upward eliminates the initial concentric overload on the biceps.
- Drifting Elbows Forward: Allowing elbows to travel forward past the ribs recruits the anterior deltoids and takes tension off the biceps apex.
- Dropping the Eccentric Phase: Letting the weight fall quickly without resistance wastes 50% of the muscle-building stimulus from eccentric microtrauma.
Proper Breathing Patterns & Core Engagement
Inhale on controlled lowering (2-3s eccentric); exhale on elbow contraction to peak tension.

Injury Modification & Joint Safety
Lifters with distal biceps tendinopathy or golfer's elbow (medial epicondylitis) should use neutral-grip hammer curls or EZ-bars to reduce wrist pronation torque. If joint irritation persists, immediately stop and substitute this movement with another exercise from the Upper Arms exercises category.
Muscles Worked
The Barbell Lying Preacher Curl primarily targets the Biceps, with Forearms as the primary synergist muscle group.

FAQ
- What muscles does the Barbell Lying Preacher Curl work?
- The Barbell Lying Preacher Curl primarily targets the biceps as the primary agonist. The forearms acts as the primary supporting muscle group during force transmission. Maintaining strict biomechanical alignment ensures maximal tension remains focused on the intended muscle fibers rather than shifting to surrounding stabilizer joints.
- What equipment do I need for the Barbell Lying Preacher Curl?
- The Barbell Lying Preacher Curl is performed using a barbell. Ensure all equipment is securely positioned with collars or safety pins locked before loading working sets. If you train in a home gym or minimal setup, explore our equipment-free and resistance band alternatives below.
- What is the most common form mistake on the Barbell Lying Preacher Curl?
- The most frequent error is swinging hips & lower back: Using momentum from the hips to swing the weight upward eliminates the initial concentric overload on the biceps.. Controlling the 2 to 3-second eccentric lowering phase ensures maximal hypertrophic stimulus while shielding connective tissue.
- How many sets and reps should I perform on the Barbell Lying Preacher Curl?
- For muscle growth and density, execute 3 to 4 working sets of 10 to 15 controlled repetitions with 60 seconds rest, emphasizing a deep stretch and deliberate peak contraction on every rep.
- What's a good alternative to the Barbell Lying Preacher Curl?
- If you don't have access to a barbell, the Biceps Leg Concentration Curl targets the same biceps using body weight instead. This alternative replicates the same joint angle and movement plane while allowing you to train effectively with different available gear.
