5 Best Arm Exercises for Beginners to Build Bigger Biceps

Building bigger biceps is a primary goal for many beginners embarking on their fitness journey. The biceps brachii is a two-headed muscle that plays a key role in elbow flexion and forearm supination, both crucial for upper-body strength and aesthetics.

This article details five of the most effective arm exercises for hypertrophy and strength, supported by scientific research, and offers practical insights for beginners looking to build bigger biceps safely and efficiently.

Why Focus on Biceps Development?

Developing the biceps not only improves arm size but also contributes to overall upper-body strength and performance in compound movements like pull-ups and rows. According to Schoenfeld (2010), muscle hypertrophy is optimised through mechanical tension, muscle damage, and metabolic stress, all of which are effectively targeted in well-designed biceps exercises.

Key Training Principles for Biceps Growth

For beginners, understanding fundamental training principles is essential:

Progressive overload: Consistently increasing resistance or volume is necessary to stimulate ongoing muscle growth (Schoenfeld, 2010).

Exercise selection: Choosing exercises that target both the short and long head of the biceps ensures balanced development.

Tempo and form: Controlled repetitions with a full range of motion enhance muscle activation and reduce injury risk (Welsch et al., 2005).

Training frequency: Research by Gentil et al. (2015) supports training biceps 2-3 times per week for optimal hypertrophic response in beginners.

Best Arm Exercises for Beginners

1. Barbell Bicep Curl

The barbell bicep curl is a fundamental compound-isolation hybrid movement. It allows for the use of heavier loads compared to dumbbells, making it ideal for building strength and size.

Muscles targeted: Biceps brachii (short and long head), brachialis, and brachioradialis.

How to perform: Stand upright holding a barbell with a supinated (palms-up) grip, hands shoulder-width apart. Keep your elbows tucked in and curl the barbell up to shoulder height. Lower it under control.

Scientific rationale: A study by Oliveira et al. (2009) showed that the barbell curl resulted in significantly higher biceps activation compared to other variations, making it ideal for hypertrophy in beginners.

Form tips: Avoid swinging the body. Keep your torso still to maximise tension on the biceps.

2. Dumbbell Hammer Curl

The hammer curl targets both the biceps and brachialis, the latter contributing to overall arm thickness.

Muscles targeted: Biceps brachii, brachialis, brachioradialis.

How to perform: Hold dumbbells by your sides with a neutral grip (palms facing your torso). Curl the weights while maintaining the neutral grip. Lower slowly.

Scientific rationale: The brachialis is often undertrained but plays a major role in arm volume. Research by Pinto et al. (2014) indicated that including variations like hammer curls leads to more comprehensive muscle activation.

Form tips: Maintain a neutral wrist and slow eccentric phase (lowering) to maximise time under tension.

3. Concentration Curl

The concentration curl isolates the biceps to a high degree and is effective for improving the mind-muscle connection, which is vital for beginners.

Muscles targeted: Biceps brachii (primarily the short head).

How to perform: Sit on a bench, rest your elbow against the inside of your thigh, and curl a dumbbell upwards. Focus on squeezing at the top. Lower with control.

Scientific rationale: A landmark EMG study by Boeckh-Behrens and Buskies (2000) found the concentration curl to elicit the highest muscle activation in the biceps brachii among all curl variations.

Form tips: Do not swing or use momentum. Isolate the biceps by keeping the elbow fixed and moving only the forearm.

4. Incline Dumbbell Curl

This variation stretches the biceps under load, especially the long head, which is important for achieving the biceps peak.

Muscles targeted: Long head of the biceps brachii.

How to perform: Sit on an incline bench set at 45-60 degrees. Let the arms hang behind the body holding dumbbells. Curl while keeping the shoulders retracted. Lower slowly.

Scientific rationale: The incline curl allows for increased activation of the long head due to the extended shoulder position (Staudenmann et al., 2010), which is crucial for balanced biceps development.

Form tips: Keep elbows behind the body throughout the movement. Avoid shrugging or rolling the shoulders forward.

5. Cable Bicep Curl

Cable resistance provides consistent tension throughout the range of motion, which free weights may lack at certain angles.

Muscles targeted: Biceps brachii, with constant tension from start to finish.

How to perform: Attach a straight bar to the low pulley of a cable machine. Stand upright and curl the bar while keeping your elbows tucked. Squeeze at the top.

Scientific rationale: Schick et al. (2010) demonstrated that cables maintain higher average muscle tension over time, which is beneficial for hypertrophy, particularly in beginners.

Form tips: Adjust the height of the pulley so that the movement starts with a stretch on the biceps. Focus on steady, smooth motion.

Structuring a Beginner Arm Workout

For beginners, training biceps 2-3 times per week with adequate recovery between sessions is optimal. A sample session might look like this:

• Barbell Curl: 3 sets of 8-12 reps
• Dumbbell Hammer Curl: 3 sets of 10-15 reps
• Concentration Curl: 3 sets of 12 reps

Alternate with incline curls and cable curls in subsequent sessions to ensure all heads of the biceps are targeted evenly. Begin with lighter loads to practise form and progressively increase resistance as strength improves.

Recovery and Growth Considerations

Muscle growth occurs during recovery. Beginners should prioritise:

• Nutrition: Consuming sufficient protein (1.6-2.2g per kg of body weight per day) to support muscle synthesis (Morton et al., 2018).
• Sleep: At least 7-9 hours per night to facilitate growth hormone release and recovery (Dattilo et al., 2011).
• Rest days: Allowing 48 hours before re-training the same muscle group helps avoid overtraining and injury (American College of Sports Medicine, 2009).

Avoiding Common Mistakes

1. Using too much weight: Leads to poor form and increases injury risk. Focus on technique first.
2. Neglecting the eccentric phase: Lowering the weight slowly has been shown to increase hypertrophy (Roig et al., 2009).
3. Lack of variety: Repeating the same exercise limits growth. Rotate movements every few weeks.
4. Overtraining: More is not always better. Quality over quantity is essential for progress.
