Best Biceps Exercises: Build Bigger, Stronger, and More Defined Arms

biceps exercises

Biceps are one of the most trained muscle groups in the gym — and one of the most misunderstood. Most people do a few sets of curls, wonder why their arms aren’t growing, and move on. The reality is that truly well-developed biceps require more than just picking a curl variation and repeating it every week. Different grips, different angles, and different resistance profiles all contribute to complete bicep development in ways that no single exercise can cover alone.

This guide covers all 11 biceps exercises on this site, what makes each one unique, and how to combine them into a smart, complete arm training program.

Understanding Your Biceps Muscles

The biceps is made up of more muscles than most people realise:

Biceps brachii (long head) — the outer head of the bicep, responsible for that high, peaked look when the arm is flexed. It’s best targeted through exercises that stretch the bicep at the start of the movement — like incline dumbbell curls and overhead cable curls.

Biceps brachii (short head) — the inner head, responsible for the width and fullness of the bicep when viewed from the front. It’s best targeted through exercises where the arm is in a forward position — like preacher curls and concentration curls.

Brachialis — a muscle sitting underneath the biceps that adds significant thickness to the upper arm and pushes the bicep upward when developed. It responds best to a neutral grip — which is why hammer curls are so important. Many people have underdeveloped brachialis, which limits how impressive their arms look even with a big bicep.

Brachioradialis — a forearm muscle that runs along the outer forearm and assists significantly with neutral grip curls. Well-developed brachioradialis adds thickness to the forearm and completes the look of a big arm.

The Three Keys to Complete Bicep Development

1. Grip variation — your grip determines which muscles are emphasized. Supinated (underhand) grips maximize biceps activation. Neutral grips (hammer curls) shift emphasis to the brachialis and brachioradialis. Rotating between both is essential for complete arm development.

2. Angle variation — the angle of your arm relative to your torso changes which part of the bicep is most stretched and loaded. Arms behind the torso (incline curls) maximally stretch the long head. Arms forward (preacher curls) load the short head in a shortened position for peak contraction. Arms overhead (overhead cable curl) create a unique long head stretch that no other position provides.

3. Resistance type — free weights provide peak resistance at parallel and minimal tension at the bottom and top. Cables provide constant tension throughout the full range. Both are valuable and complement each other for complete bicep stimulus.

The Best Biceps Exercises

1. Chin-Ups

Chin-ups are the most underrated biceps exercise in existence. The underhand grip combined with your full bodyweight makes them one of the most effective mass builders for the biceps — and they simultaneously build serious back width and pulling strength. If you can only choose one compound biceps exercise, make it chin-ups. Start your session with these while your strength is at its peak.

2. Barbell Curl

The barbell curl is the go-to exercise for building biceps mass and strength. The fixed bar allows you to load heavier than dumbbells and keeps both arms working in a consistent supinated position throughout every rep — maximizing biceps activation. It’s the exercise where you can push the most total weight through your biceps, making it the foundation of any serious arm training program.

3. Dumbbell Curls

Dumbbell curls are the unilateral version of the barbell curl — training one arm at a time allows each bicep to work through its own natural range of motion and helps correct any strength imbalances between your left and right arm. They’re also more versatile than the barbell curl, since you can alternate arms, do both simultaneously, or adjust the angle and rotation on the fly. A staple of every arm training program.

4. Preacher Curl

The preacher curl is the strictest biceps isolation exercise you can do. By bracing your upper arms against the angled pad, all possibility of swinging or using body momentum is completely eliminated — your biceps have to do every single rep on their own. The forward arm position particularly emphasises the short head of the biceps, making it one of the best exercises for developing that sharp biceps peak. Use an EZ bar for wrist comfort.

5. Incline Dumbbell Curls

The incline dumbbell curl is one of the most underrated biceps exercises in the gym. By lying back on an incline bench, your arms hang behind your torso — creating a deeper stretch on the long head of the biceps than almost any other variation can achieve. That stretched starting position is one of the most powerful stimuli for long head development and biceps peak. If a high, peaked bicep is your goal, this exercise is essential.

6. Concentration Curls

Concentration curls are the finishing exercise of the biceps world — famously used by Arnold Schwarzenegger as a key tool for developing his legendary biceps peak. By bracing your upper arm against your inner thigh, the exercise eliminates all momentum and puts your biceps in complete isolation. The forward arm position maximises short head contraction at the top of each rep for an intense peak squeeze. Best used at the end of your biceps session as a focused burnout.

7. Alternate Hammer Curl

The alternate hammer curl is the most important exercise most arm trainers neglect. The neutral grip shifts significant emphasis to the brachialis — the muscle that sits underneath the bicep and pushes it upward when developed. A well-trained brachialis makes your arms look dramatically thicker and more impressive from every angle, not just the front. If your arms look good when flexed but flat otherwise, underdeveloped brachialis is usually the reason.

8. Standing Biceps Cable Curl

The standing biceps cable curl provides constant tension throughout the entire range of motion — including at the very bottom where dumbbells and barbells provide almost no resistance. This different resistance profile means your biceps are loaded from the first degree of the curl all the way through to the squeeze at the top, creating a more complete stimulus than free weight curls alone. An excellent complement to barbell and dumbbell work.

9. Cable Hammer Curls

Cable hammer curls combine the brachialis-targeting neutral grip of the hammer curl with the constant tension of the cable machine. The rope attachment also allows a unique pull-apart technique at the top of each rep that intensifies the brachialis and brachioradialis contraction beyond what dumbbells can deliver. A great way to get more out of your hammer curl training without simply adding more dumbbell sets.

10. Overhead Cable Curl

The overhead cable curl is one of the most unique biceps exercises you can do. With the pulley set high and your arm extended overhead, the long head of the biceps is placed under maximum stretch before you even begin the curl — combined with constant cable tension throughout. This creates a stimulus for the long head that no other exercise on this list provides. If biceps peak and length are priorities, the overhead cable curl fills a gap everything else leaves.

11. Low Pulley Bicep Cable Curl

The low pulley bicep cable curl is the single-arm cable curl variation — training each arm individually with constant cable tension. It’s particularly valuable for addressing strength imbalances between arms and for improving the mind-muscle connection with each bicep separately. Because it’s unilateral, it also demands more core stability to prevent torso rotation, adding an extra element of control to the exercise.

How to Structure Your Biceps Workout

A complete biceps workout should cover heavy compound work, strict isolation, stretch-focused training, and constant tension:

Start with your heaviest compound work — chin-ups or barbell curls first while your biceps are fresh and your strength is at its peak.

Follow with stretch-focused isolation — incline dumbbell curls or overhead cable curls to target the long head through a stretched position.

Add strict isolation work — preacher curls or concentration curls for maximum short head activation with zero momentum.

Finish with cable work — standing cable curls or cable hammer curls for constant tension and a thorough pump to end the session.

Biceps Exercises – Training Tips for Maximum Biceps Growth

Control the lowering phase on every rep. The eccentric — the slow lowering of the weight — is one of the most powerful stimuli for biceps growth. Lower the weight over 2–3 seconds on every rep rather than letting gravity do the work. This one change makes more difference to bicep development than almost anything else.

Keep your elbows pinned to your sides. On all standing curl variations, your elbows should act as a fixed pivot point. The moment they drift forward, your shoulders start helping and your biceps do less work. Keep them still and let your forearms do all the moving.

Squeeze hard at the top of every rep. The peak contraction — when your arm is fully curled and your bicep is fully shortened — is where a lot of the development signal comes from. Don’t rush past it. Hold for a full second and squeeze as hard as you can before lowering.

Use both free weights and cables. Free weights and cables provide different resistance profiles that complement each other. Free weights allow heavier loading, cables provide constant tension. Using both in the same session gives your biceps a more complete stimulus than either alone.

Train biceps 2 times per week. Biceps are a small muscle group that recovers relatively quickly. Two sessions per week with different exercise focuses works well for most people — for example, one session focusing on barbell and dumbbell work, one focusing on cables and strict isolation.

Biceps Exercises – Common Mistakes to Avoid

Using too much weight. The most common biceps mistake by far. Heavy curls with swinging and momentum mean your back and shoulders are doing most of the work. Drop the weight, use strict form, and feel your biceps actually working — the results will be dramatically better.

Only doing one type of curl. Doing only barbell curls, or only dumbbell curls, means you’re missing the long head stretch, the short head peak contraction, the brachialis work, and the constant tension benefits that other variations provide. Variety is essential for complete bicep development.

Neglecting hammer curls. The brachialis is one of the most impactful muscles for arm size and most people never directly train it. Add hammer curls to every bicep session and your arms will look noticeably thicker within months.

Ignoring the eccentric phase. Curling up explosively and dropping the weight back down is one of the least effective ways to train biceps. The slow lowering phase is where much of the muscle damage and growth stimulus occurs — don’t skip it.

Training biceps before back. If you train back and biceps on the same day, always do your back work first. Back exercises already fatigue the biceps heavily — training biceps first means your back work suffers significantly.

Biceps Exercises – Final Thoughts

Building bigger biceps requires more than just doing random curls. By combining heavy lifts, strict isolation, and constant tension exercises, you can fully develop your arms for both strength and aesthetics.
