The Cable Lying Close-Grip 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.

A close grip on a lying cable curl narrows the hand position to emphasize the inner head of the biceps, similar to what a close-grip standing curl does but with the added strictness of lying flat. Because the body is pinned to the bench, cheating the rep with hip drive isn't really an option here. It's a good finishing exercise once heavier curling work for the session is already done.

How to Do the Cable Lying Close-Grip Curl

  1. Attach a straight bar to a low pulley cable machine.
  2. Lie face up on a flat bench with your feet flat on the floor.
  3. Grip the bar with an underhand grip, hands shoulder-width apart.
  4. Fully extend your arms, keeping your elbows close to your sides.
  5. Without moving your upper arms, curl the bar toward your chest by contracting your biceps.
  6. Pause briefly at the top, squeezing your biceps.
  7. Slowly lower the bar back to the starting position, fully extending your arms.
  8. Repeat for your target rep goal, keeping your core engaged and avoiding any reliance on momentum.

Form & Eccentric Control 2 – 3 Sets × 12 – 15 Reps

Controlled 3s eccentric · 60s rest

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 Cable Lying Close-Grip Curl primarily targets the Biceps, with Forearms as the primary synergist muscle group.

FAQ

What muscles does the Cable Lying Close-Grip Curl work?
The Cable Lying Close-Grip 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 Cable Lying Close-Grip Curl?
The Cable Lying Close-Grip Curl is performed using a cable. 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 Cable Lying Close-Grip 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 Cable Lying Close-Grip 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 Cable Lying Close-Grip Curl?
If you don't have access to a cable, 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. You can also substitute it seamlessly in our free Workout Plan Builder.
