Bigger, stronger biceps aren’t built through random curling—they’re built through intelligent programming grounded in biomechanics and science. The biceps brachii is a two-headed muscle that flexes the elbow, supinates the forearm, and assists in shoulder flexion. To maximize growth, you need to target all these functions across different movement angles, grips, and loads.
This article breaks down the 10 best exercises for biceps hypertrophy and strength, supported by peer-reviewed research and expert biomechanical reasoning.
Understanding Biceps Anatomy and Function
The biceps brachii has two distinct heads: the long head, originating from the supraglenoid tubercle of the scapula, and the short head, from the coracoid process. Both insert into the radial tuberosity and bicipital aponeurosis, allowing them to act across both the shoulder and elbow joints.
The muscle’s primary roles are:
- Elbow flexion
- Forearm supination
- Shoulder flexion (minor contribution)
Training the biceps effectively means targeting these movements through varied grip orientation and shoulder positioning. Research shows that combining multiple angles and grips maximizes hypertrophy and neural activation (Schoenfeld et al., 2014).
1. Barbell Bicep Curl
The barbell curl is the foundational mass builder for the biceps. It allows heavy mechanical loading through a stable bilateral setup.
Technique
- Grip a straight bar shoulder-width apart with supinated hands.
- Curl the bar toward your shoulders while keeping elbows close to your sides.
- Lower under control to full elbow extension.
Why It Works
This movement provides significant mechanical tension—one of the primary drivers of muscle growth (Schoenfeld, 2010). EMG analyses show high activation in both the long and short heads of the biceps, particularly in the mid-range of the motion (Oliveira et al., 2009).
2. Dumbbell Supinating Curl
Using dumbbells allows for a natural wrist rotation that better engages the biceps’ supination function.
Technique
- Start with a neutral grip.
- As you curl, rotate the wrist so your palm faces up at the top.
- Lower in reverse order.
Why It Works
The rotational component maximally activates the biceps brachii compared to non-supinating curls (Signorile et al., 2002). It also helps balance muscle development between arms, addressing asymmetries.
3. Incline Dumbbell Curl
The incline position stretches the long head of the biceps, emphasizing growth through lengthened muscle tension.
Technique
- Sit on an incline bench (45–60°).
- Let arms hang straight down with palms facing forward.
- Curl both dumbbells simultaneously without letting elbows drift forward.
Why It Works
Training at long muscle lengths promotes superior hypertrophy by increasing passive tension and sarcomere addition (Maas & Sandercock, 2010). This variation specifically enhances long-head recruitment.
4. Preacher Curl
The preacher curl isolates the biceps by minimizing shoulder involvement and encouraging controlled contractions.
Technique
- Sit at a preacher bench with arms resting on the pad.
- Grip an EZ bar or dumbbell with palms up.
- Curl upward until forearms are vertical, then slowly lower.
Why It Works
The fixed arm position reduces momentum, increasing time under tension. EMG data indicate greater biceps activation at the mid-to-lower range compared with standing curls (Staudenmann et al., 2010).
5. Concentration Curl
This unilateral exercise provides maximum focus and contraction at the top of the movement.
Technique
- Sit with elbow braced against your inner thigh.
- Curl the dumbbell upward toward your shoulder.
- Lower with control.
Why It Works
A study by the American Council on Exercise (ACE, 2014) found concentration curls produce the highest mean biceps activation among tested exercises, likely due to strict form and peak contraction focus.
6. Cable Curl
Cable machines provide consistent tension throughout the range of motion, unlike free weights where gravity reduces load at the top.
Technique
- Attach a straight or EZ bar to the low pulley.
- Grip with palms up and curl toward the shoulders.
- Control the eccentric phase.
Why It Works
Constant tension increases metabolic stress, a known driver of hypertrophy (Schoenfeld, 2010). The adjustable setup also allows manipulation of resistance curves and arm angles for targeted emphasis.
7. Hammer Curl
Although it primarily targets the brachioradialis and brachialis, the hammer curl thickens the arm and contributes indirectly to biceps development.
Technique
- Hold dumbbells with neutral (hammer) grip.
- Curl upward without rotating the wrist.
- Keep elbows tight to your torso.
Why It Works
By emphasizing the brachialis, which lies beneath the biceps, you can “push” the biceps outward, enhancing overall arm size (Moritani & deVries, 1979). It also recruits forearm musculature, aiding grip strength.
8. Zottman Curl
This hybrid curl combines the benefits of supinated and pronated grips for total arm development.
Technique
- Curl the dumbbells up with a supinated grip.
- At the top, rotate palms down (pronation).
- Lower slowly through the eccentric phase.
Why It Works
The concentric phase targets the biceps brachii, while the eccentric pronated lowering heavily engages the brachioradialis. Eccentric loading is known to induce greater muscle damage and growth signaling (Roig et al., 2009).
9. Chin-Up
A compound movement that recruits both biceps and upper back muscles, the chin-up is an underrated arm-builder.
Technique
- Use a shoulder-width supinated grip.
- Pull your body until the chin clears the bar.
- Lower slowly to full extension.
Why It Works
EMG research shows that chin-ups activate the biceps nearly as strongly as isolated curls while providing systemic overload (Youdas et al., 2010). The addition of bodyweight resistance supports both strength and hypertrophy.
10. Reverse Curl
The reverse curl targets the brachioradialis and the long head of the biceps through a pronated grip, adding balance and forearm strength.
Technique
- Hold an EZ bar with an overhand grip.
- Curl up while keeping elbows stable.
- Lower under control.
Why It Works
While pronation reduces direct biceps tension, it strengthens the forearm flexors and stabilizers, improving total arm aesthetics and joint balance (Behm et al., 2002).
Programming Tips for Biceps Growth
1. Train Twice Weekly
Evidence suggests training a muscle group twice per week produces superior hypertrophy compared to once-weekly frequency (Schoenfeld et al., 2016). Aim for 10–16 sets per week spread across sessions.
2. Use Full Range of Motion
Research confirms that training through a full range of motion yields greater muscle growth than partial reps (McMahon et al., 2014). Lower the weights fully at each rep’s bottom to engage muscle fibers completely.
3. Prioritize Eccentric Control
Eccentric (lowering) phases create higher mechanical tension and muscle microtrauma, enhancing growth signals (Franchi et al., 2017). Lower each rep over 2–3 seconds.
4. Vary Angles and Equipment
Rotating between cables, dumbbells, and barbells ensures full biceps recruitment and prevents adaptive plateaus. Each implements a unique resistance curve and neural demand.
5. Focus on Progressive Overload
Consistent load progression—via weight, volume, or tempo—is the most critical driver of muscle gain (Dankel et al., 2017). Track your lifts and aim to increase either resistance or total reps over time.
Sample Biceps Workout
Workout A (Mass & Strength Focus):
- Barbell Curl – 4×8
- Chin-Up – 4×6
- Incline Dumbbell Curl – 3×10
- Hammer Curl – 3×12
Workout B (Shape & Definition Focus):
- Preacher Curl – 3×10
- Cable Curl – 3×12
- Concentration Curl – 3×12
- Zottman Curl – 2×15
Alternate both workouts across the week for optimal recovery and adaptation.
Conclusion
Building bigger, stronger biceps requires intelligent exercise selection, precise execution, and science-based progression. From mechanical tension to metabolic stress and muscle length dynamics, the key is to target every function of the biceps brachii consistently.
Combine compound lifts like chin-ups with isolated curls, train through full ranges of motion, and progressively overload over time for maximal results.
