Building bigger biceps is a common goal among fitness enthusiasts, and while traditional exercises like barbell curls are effective, there are several unique barbell movements that can target the biceps in different ways.
These exercises not only provide variation to your routine but also engage your muscles differently, potentially leading to greater hypertrophy. This article explores five unique barbell exercises for bigger biceps, supported by scientific evidence and practical guidance.
The Anatomy of the Biceps
Before diving into the exercises, it’s crucial to understand the anatomy of the biceps. The biceps brachii has two heads: the long head, which forms the outer part of the muscle, and the short head, which is located on the inner side. Both heads work together to flex the elbow, supinate the forearm, and assist in shoulder flexion (Haff & Triplett, 2016). Effective training should target both heads for balanced growth and strength.
1. Barbell Drag Curl
The barbell drag curl shifts emphasis from the forearms and brachialis to the biceps, providing a unique stimulus for growth. Instead of lifting the bar in a traditional curling motion, the bar is dragged along the torso, minimising shoulder involvement.
How to Perform:
- Hold the barbell with an underhand grip, slightly wider than shoulder-width.
- Keep your elbows tucked and drag the barbell upward, keeping it close to your torso.
- Lower the barbell slowly and repeat for 10–12 repetitions.
Benefits:
- Enhances the isolation of the biceps by reducing momentum and deltoid activation.
- Promotes a stronger mind-muscle connection.
Supporting Science:
Research suggests that altering exercise mechanics can enhance muscle activation (Schoenfeld, 2010). By minimising shoulder involvement, the drag curl ensures that the biceps bear the brunt of the load.
2. Barbell Reverse Curl
While commonly associated with forearm development, the barbell reverse curl also targets the brachialis muscle, which sits underneath the biceps. Developing the brachialis adds width and thickness to the upper arm.
How to Perform:
- Hold the barbell with an overhand grip, hands slightly narrower than shoulder-width.
- Keep your elbows tucked and curl the barbell upwards.
- Slowly lower the barbell back to the starting position.
Benefits:
- Strengthens the brachialis, enhancing overall upper arm size.
- Improves grip strength due to the pronated grip.
Supporting Science:
A study by McGill et al. (2014) demonstrated that pronated grip exercises engage the brachialis more effectively, contributing to arm hypertrophy.
3. Barbell Spider Curl
The barbell spider curl is performed on an incline bench, allowing for full elbow extension and greater range of motion. This variation isolates the biceps, minimising cheating or momentum.
How to Perform:
- Lie face down on an incline bench with your arms hanging straight down, holding a barbell with an underhand grip.
- Curl the barbell upwards while keeping your upper arms stationary.
- Lower the barbell in a controlled manner and repeat.
Benefits:
- Provides constant tension on the biceps throughout the movement.
- Encourages strict form, reducing the risk of injury.
Supporting Science:
Research by Vigotsky et al. (2018) highlights that exercises with a longer range of motion can lead to greater muscle hypertrophy by maximising stretch and contraction phases.
4. Barbell Zottman Curl
The Zottman curl combines a supinated curl during the upward phase and a pronated grip during the lowering phase, targeting the biceps and forearms simultaneously. This dual-action movement enhances both size and strength.
How to Perform:
- Start with an underhand grip and curl the barbell upwards.
- At the top, rotate your wrists into a pronated grip.
- Lower the barbell with this grip, focusing on controlled movement.
Benefits:
- Targets both the biceps (supinated phase) and forearms (pronated phase).
- Builds functional strength by engaging multiple muscle groups.
Supporting Science:
Research has shown that combining supinated and pronated grips increases overall arm activation (Schoenfeld, 2010). The Zottman curl exploits this principle effectively.
5. Barbell Preacher Curl
The preacher curl utilises a preacher bench to isolate the biceps and eliminate momentum. This exercise emphasises the eccentric phase, promoting muscle growth.
How to Perform:
- Sit at a preacher bench with your arms resting on the pad, holding a barbell with an underhand grip.
- Curl the barbell upwards, squeezing your biceps at the top.
- Lower the barbell slowly to maximise tension on the eccentric phase.
Benefits:
- Isolates the biceps, reducing the involvement of secondary muscles.
- Emphasises the eccentric phase, which is critical for hypertrophy.
Supporting Science:
Eccentric training has been shown to induce greater muscle damage and growth compared to concentric training (Douglas et al., 2017). The preacher curl’s design maximises this effect.
Practical Tips for Barbell Biceps Training
Progressive Overload:
To grow your biceps, progressively increase the resistance over time. This forces your muscles to adapt and grow (Haff & Triplett, 2016).
Volume and Intensity:
Studies suggest that 8–12 repetitions per set, performed with 3–4 sets per exercise, is optimal for hypertrophy (Schoenfeld et al., 2014).
Rest Periods:
Rest for 60–90 seconds between sets to maintain intensity while allowing partial recovery.
Nutrition:
Adequate protein intake (1.6–2.2 g/kg of body weight) is crucial for muscle repair and growth (Morton et al., 2018).
