Building bigger biceps is a primary goal for many men aiming to increase their upper body strength and aesthetics. While isolation exercises like dumbbell curls are useful, barbell exercises offer a greater advantage by engaging multiple muscle groups, allowing for increased loading and progressive overload. This article explores three top barbell exercises that can stimulate faster bicep growth, supported by scientific research.
The Importance of Compound Movements for Bicep Growth
Before delving into the exercises, it’s important to understand the role of compound movements in muscle hypertrophy. Compound exercises, which involve multiple joints and muscle groups, tend to stimulate more overall muscle growth compared to isolation exercises. Research published in the Journal of Strength and Conditioning Research shows that exercises that recruit more muscle fibres lead to greater increases in muscle mass and strength due to the larger load potential (Schoenfeld, 2010).
This is because compound movements allow for a greater overall workload, which in turn causes greater metabolic stress and mechanical tension – two key drivers of muscle growth (Schoenfeld, 2016).
The biceps, specifically the biceps brachii, are primarily responsible for flexion at the elbow and supination of the forearm. They also assist with shoulder flexion. While isolation exercises target only these functions, compound barbell exercises allow for greater activation and stimulation of the biceps in synergy with other upper body muscles. This allows for heavier weights and more total volume to be lifted, resulting in faster muscle growth.
1. Barbell Curl
Why the Barbell Curl is Effective
The barbell curl is a fundamental exercise for bicep growth. It directly targets the biceps brachii, while also engaging the brachialis and brachioradialis to a lesser degree. The advantage of the barbell curl over dumbbell curls lies in its bilateral nature, allowing for more even loading and greater overall weight to be lifted. Additionally, the barbell curl allows for increased mechanical tension, one of the key factors in hypertrophy (Schoenfeld, 2010).
How to Perform the Barbell Curl
- Stand with your feet shoulder-width apart, holding the barbell with an underhand grip.
- Keep your elbows tucked close to your torso.
- Curl the barbell upwards, contracting your biceps.
- Slowly lower the barbell back to the starting position, maintaining control throughout the movement.
Scientific Support for the Barbell Curl
Studies have consistently shown the barbell curl to be one of the most effective exercises for bicep activation. A study published in the Journal of Applied Biomechanics found that bicep curls performed with a barbell resulted in significantly greater activation of the biceps compared to cable machines or dumbbells (McMahon et al., 2014). This is due to the ability to handle more weight, resulting in greater mechanical tension.
2. Underhand Barbell Row
Why the Underhand Barbell Row Works for Bicep Growth
While commonly regarded as a back exercise, the underhand barbell row is also highly effective for stimulating bicep growth. By adopting an underhand grip, the biceps are placed in a stronger position to assist with the rowing movement. This dual engagement of the biceps and back muscles allows for increased load, leading to greater mechanical tension and muscle activation.
Underhand rows engage the biceps throughout the pulling motion, especially in the eccentric (lowering) phase. Eccentric contractions are known to cause more muscle damage, which can lead to greater muscle growth during recovery (Hedayatpour & Falla, 2015). Additionally, research published in the European Journal of Applied Physiology demonstrated that exercises involving eccentric loading can lead to significant increases in muscle mass compared to concentric-only movements (Douglas et al., 2017).
How to Perform the Underhand Barbell Row
- Stand with your feet shoulder-width apart, holding a barbell with an underhand grip.
- Bend your knees slightly and hinge forward at your hips, keeping your back flat.
- Pull the barbell towards your lower abdomen, squeezing your shoulder blades together.
- Slowly lower the barbell back to the starting position.
Scientific Backing for the Underhand Row
In a study conducted by The Journal of Strength and Conditioning Research, it was found that the biceps were highly activated during underhand rowing exercises, especially when the elbows were kept close to the body (Lehman et al., 2004). The increased load that can be lifted with the barbell row compared to isolation exercises also provides the opportunity for greater progressive overload, which is a critical factor for hypertrophy (Schoenfeld, 2016).
3. Barbell Drag Curl
Why the Barbell Drag Curl is an Effective Variation
The barbell drag curl is a variation of the traditional barbell curl that places greater emphasis on the biceps by minimising the involvement of the shoulders and forearms. In this exercise, the barbell is “dragged” up the body rather than curled in an arc, placing the biceps in a more advantageous position for hypertrophy. By reducing shoulder involvement, the drag curl ensures that the biceps are the primary muscles engaged throughout the movement, leading to greater activation and mechanical tension.
Mechanical tension is one of the most important factors in muscle growth. A study published in the Journal of Strength and Conditioning Research highlights that increasing mechanical tension through greater activation of the target muscle can lead to enhanced muscle hypertrophy (Schoenfeld, 2016). By isolating the biceps more effectively, the drag curl maximises this tension.
How to Perform the Barbell Drag Curl
- Stand with your feet shoulder-width apart, holding the barbell with an underhand grip.
- Keep the barbell close to your body and drag it upwards, allowing your elbows to move backwards.
- Squeeze your biceps at the top of the movement before slowly lowering the barbell back to the starting position.
- Keep your elbows pointing behind you throughout the movement to prevent shoulder involvement.
Evidence Supporting the Barbell Drag Curl
While less commonly performed than the traditional barbell curl, the drag curl offers unique advantages in isolating the biceps. Research on muscle activation patterns has shown that variations in grip and elbow position can significantly alter muscle recruitment, allowing for greater tension on the target muscles (Schoenfeld, 2016). The drag curl’s emphasis on elbow positioning enhances bicep engagement while minimising shoulder involvement, making it a highly effective exercise for hypertrophy.
Training Protocol for Maximum Growth
Volume and Frequency
Research shows that muscle hypertrophy is optimised when a combination of sufficient volume, frequency, and intensity is applied. According to a study published in Sports Medicine, performing between 10-20 sets per muscle group per week provides optimal volume for muscle growth (Schoenfeld et al., 2019). For the biceps, this means incorporating 3-4 sets of each of the exercises mentioned above into your weekly routine, ideally split across two to three days.
Progressive Overload
Progressive overload is a key principle for muscle growth. As your biceps adapt to a certain load, it’s important to gradually increase the weight or the number of repetitions to continue stimulating growth. This is supported by research from The Journal of Strength and Conditioning Research, which found that gradual increases in load lead to greater hypertrophy over time (Schoenfeld, 2010).
Rest and Recovery
Muscles grow during rest, not during training. Therefore, it’s important to give your biceps sufficient time to recover between training sessions. Research published in the Journal of Applied Physiology recommends a minimum of 48 hours of rest between sessions targeting the same muscle group (Damas et al., 2016).
Common Mistakes to Avoid
Using Too Much Weight
One of the most common mistakes is using too much weight, which compromises form and reduces the effectiveness of the exercise. A study published in The Journal of Applied Physiology found that maintaining proper form and full range of motion leads to greater muscle activation than performing partial repetitions with heavier weights (Kraemer et al., 2014).
Not Controlling the Eccentric Phase
The eccentric (lowering) phase of an exercise plays a crucial role in stimulating muscle growth. Studies show that eccentric loading causes greater muscle damage and, as a result, more hypertrophy (Douglas et al., 2017). Ensure you control the barbell throughout the entire range of motion, especially during the lowering phase, to maximise growth.
Conclusion
Incorporating barbell exercises into your routine is one of the most effective ways to force faster bicep growth. The barbell curl, underhand barbell row, and drag curl each provide unique benefits for hypertrophy by increasing mechanical tension, allowing for greater load, and engaging the biceps through compound movements. To maximise results, focus on progressive overload, maintain proper form, and ensure adequate recovery between workouts.
