Biceps Training: Targeting the Long Head for Peak Development

By Alex 7 min read

To effectively target the long head of the biceps, select exercises that leverage shoulder extension and full forearm supination, emphasizing controlled eccentric phases and strict form to maximize its activation and promote peak development.

How to hit a long head bicep?

Targeting the long head of the biceps brachii involves specific exercise selection and biomechanical manipulation that emphasizes its unique anatomical path across the shoulder joint, primarily through positions of shoulder extension and supination.

Understanding Biceps Anatomy: The Long and Short Heads

The biceps brachii is a two-headed muscle located on the anterior aspect of the upper arm. Both heads originate from the scapula (shoulder blade) and insert onto the radius (forearm bone), allowing them to flex the elbow and supinate the forearm. However, their distinct origins give them slightly different roles and make them amenable to targeted emphasis.

  • Long Head (Caput Longum): Originates from the supraglenoid tubercle of the scapula, superior to the glenoid cavity. Its tendon passes through the shoulder joint capsule, making it biarticular (crossing both the shoulder and elbow joints). This unique path means its tension is highly influenced by shoulder position.
  • Short Head (Caput Breve): Originates from the coracoid process of the scapula. It lies medial to the long head and does not cross the shoulder joint capsule.

While both heads work synergistically during most curling movements, the long head's involvement in shoulder flexion and its origin point allows for specific biomechanical strategies to emphasize its activation.

Why Target the Biceps Long Head?

Targeting the long head of the biceps offers several benefits:

  • Aesthetics: The long head contributes significantly to the "peak" of the biceps when flexed, giving the arm a fuller, more developed appearance.
  • Balanced Development: Focusing on both heads ensures comprehensive muscular development, reducing imbalances and potential for injury.
  • Functional Strength: A strong long head contributes to overall arm and shoulder stability, particularly in movements requiring elbow flexion and forearm supination, especially when the arm is extended behind the body.

Biomechanical Principles for Long Head Emphasis

To effectively target the long head, we leverage its anatomical position and function:

  • Shoulder Extension/Hyperextension: When the arm is positioned behind the body (shoulder extension), the long head of the biceps is maximally stretched at its origin. This pre-stretching can increase its activation during elbow flexion, as muscles tend to generate more force from a lengthened position (length-tension relationship).
  • Full Forearm Supination: While both heads contribute to supination, performing curls with a supinated (palms-up) grip ensures maximal biceps involvement, and the long head plays a significant role in this action.
  • Controlled Eccentric Phase: Emphasizing the lowering (eccentric) portion of the curl, particularly when the long head is under stretch, can promote greater muscle damage and subsequent hypertrophy.
  • Mind-Muscle Connection: Actively focusing on squeezing the biceps and feeling the long head contract throughout the movement can enhance neural drive and recruitment.

Top Exercises for Targeting the Biceps Long Head

Based on the biomechanical principles, certain exercises are superior for emphasizing the long head:

  1. Incline Dumbbell Curl:

    • Why it works: Sitting on an incline bench positions your arms behind your torso, placing your shoulders in extension. This pre-stretches the long head of the biceps, making it the primary mover during the curl.
    • Execution: Sit on an incline bench set at 45-60 degrees. Let your arms hang straight down, palms facing forward. Curl the dumbbells up, keeping your elbows stationary and close to your body. Squeeze at the top, then slowly lower the weights, maintaining tension.
  2. Spider Curl:

    • Why it works: Performed lying prone on an incline bench, the spider curl keeps your elbows in front of your body, minimizing anterior deltoid involvement and isolating the biceps. While it doesn't offer the same stretch as incline curls, the strict form and isolation can help emphasize peak contraction and tension on the long head.
    • Execution: Lie chest-down on an incline bench set at 45-60 degrees, allowing your arms to hang straight down towards the floor. Use a barbell or dumbbells. Curl the weight up, squeezing your biceps at the top, then slowly lower.
  3. Cable Curls (with specific setup):

    • Why it works: Cables provide constant tension throughout the entire range of motion, which can be beneficial for hypertrophy. By stepping slightly back and allowing your arms to extend fully, you can achieve a good stretch on the long head.
    • Execution: Stand facing a low cable pulley with a straight bar or EZ bar attachment. Take a step or two back to create tension. Keep your elbows tucked in and curl the bar up towards your chest. Slowly lower the weight under control.
  4. Concentration Curl:

    • Why it works: While often lauded for overall biceps development and peak contraction, the strict isolation and ability to focus on the contraction can help ensure the long head is fully engaged, especially if you emphasize supination.
    • Execution: Sit on a bench, lean forward, and rest your elbow against the inside of your thigh (or against a preacher curl bench). Let the dumbbell hang down. Curl the weight up, focusing on squeezing the biceps. Slowly lower.

Optimizing Your Long Head Bicep Training

  • Focus on Form over Weight: Lifting too heavy can lead to compensatory movements, reducing the isolation of the long head. Prioritize strict form and a full range of motion.
  • Controlled Tempo: Emphasize the eccentric (lowering) phase, taking 2-3 seconds to lower the weight. This increases time under tension and can lead to greater muscle growth.
  • Full Range of Motion: Ensure you get a complete stretch at the bottom of the movement and a full contraction at the top.
  • Supination: For dumbbell curls, start with a neutral grip and supinate your forearm as you curl up, finishing with palms facing your shoulders. This maximizes biceps activation.

Common Mistakes to Avoid

  • Using Momentum (Cheating): Swinging the weight reduces tension on the biceps and shifts the load to other muscles (e.g., lower back, shoulders).
  • Excessive Elbow Flare: Allowing your elbows to move forward or out during the curl reduces the isolation on the biceps. Keep them relatively fixed.
  • Not Fully Extending: Shortening the range of motion limits the stretch on the long head, reducing its activation potential.
  • Ignoring Mind-Muscle Connection: Just going through the motions without actively feeling the muscle work will yield suboptimal results.

Integrating Long Head Training into Your Program

Incorporate 1-2 exercises specifically targeting the long head into your arm or pull day routine.

  • Rep Ranges: Aim for 8-15 repetitions per set for hypertrophy.
  • Sets: Perform 3-4 sets per exercise.
  • Frequency: Train biceps 1-2 times per week, allowing adequate recovery.
  • Progressive Overload: Gradually increase the weight, reps, or sets over time to continually challenge the muscle.

Conclusion

While complete isolation of a single muscle head is anatomically challenging, strategic exercise selection and precise execution can significantly emphasize the long head of the biceps brachii. By understanding its unique origin and leveraging biomechanical principles like shoulder extension and full supination, you can effectively target this crucial muscle, contributing to both the aesthetics and functional strength of your arms. Remember that consistency, proper form, and progressive overload are paramount for maximizing results.
