Trying to Build Your Arms?Try These 8 Proven Exercises
Whether your goal is to look more defined in your sleeves, improve upper body strength, or achieve a more balanced physique, arm training plays an important role in a well-rounded fitness plan.
However, spending long hours doing biceps curls with light weights typically doesn’t lead to the muscle growth most people aim for.
To build bigger, stronger arms, you need a smart mix of exercises, gradually increasing the workload, maintaining proper form, and ensuring both the front and back of your upper arms develop evenly.
Here’s a detailed explanation of how arm growth works, along with eight effective exercises tuo help you enhance your arm training.
Understanding the Upper Arm: Biceps vs.Triceps
To get the most out of your workouts, it’s important to know which muscles you’re targeting.
A common mistake many people make is focusing too much on the biceps while ignoring the triceps.
* The Triceps Brachii: This muscle accounts for around 60 to 65% of the total upper arm size.
It is located on the back of the arm and consists of three parts: the lateral, medial, and long head.If your main goal is to increase arm size, then training the triceps with heavier weights is essential.
* The Biceps Brachii: This makes up approximately 35 to 40% of the upper arm.
It has two parts (short head and long head) and is responsible for bending the elbow and rotating the forearm so the palm faces up.
* The Brachialis: This is a muscle that lies beneath the lower part of the biceps.
Training the brachialis helps lift the biceps, creating a wider arm shape and better definition.
| UPPER ARM MASS DISTRIBUTION |
| |
| [ Triceps Brachii (~60-65%) ] [ Biceps & Brachialis (~35-40%) ]
| • Long Head • Long Head (Outer Peak) |
| • Lateral Head • Short Head (Inner Thickness) |
| • Medial Head • Brachialis (Underneath) |
Top 4 Biceps & Brachialis Exercises for Maximum Peak and Width
1.
Barbell Biceps Curl (Strict Form)
The standing barbell curl is the best isolation exercise for the biceps.
It allows you to lift heavier weights compared to dumbbells, which helps build both strength and muscle size.
* Target: Biceps Brachii (Short and Long Heads).
* Execution: Stand with your feet shoulder-width apart, holding a barbell with an underhand grip.
Keep your elbows close to your body.Curl the bar up to chest level, squeezing your biceps at the top for a second.Lower it slowly over two to three seconds.
* Pro Tip: Use an EZ curl bar if the straight barbell causes wrist pain.
2.
Incline Dumbbell Curl
The long head of the biceps crosses the shoulder joint, so placing your upper arms behind your body stretches it significantly.
This stretch helps promote muscle growth.
* Target: Biceps Brachii (Focus on the Long Head for better peak).
* Execution: Set an adjustable bench to a 45 to 60-degree angle.
Sit back with dumbbells in each hand, arms hanging straight behind your body.Curl the dumbbells upward while keeping your upper arms fixed.
* Key Advantage: Eliminates swinging and body movement, making the biceps do all the work.
3.
Dumbbell Hammer Curl
Hammer curls are important for building arm thickness and improving elbow stability.
Using a neutral grip (palms facing each other) shifts the workload from the biceps to the brachialis and brachioradialis (forearm muscles).
* Target: Brachialis and Brachioradialis.
* Execution: Stand tall, holding dumbbells at your sides with palms facing inward.
Keep your wrists neutral and curl the weights up toward your shoulders without rotating your forearms.
4.
Cable Preacher Curl
Free weights provide resistance based on gravity, but tension decreases near the top of a dumbbell curl.
Cable machines provide continuous, even tension throughout the entire movement.
* Target: Biceps Brachii (Focus on the Short Head and lower attachment).
* Execution: Position a preacher bench in front of a low cable machine.
Rest the back of your upper arms on the preacher pad.
Grab the attachment handle and lower it until your arms are almost fully extended, then curl upward while maintaining steady tension.

5.
Close-Grip Barbell Bench Press
Although compound movements like chin-ups and dips primarily target the back and chest with the arms being secondary, the close-grip bench press allows you to focus on the triceps with heavy weights in a safe and effective way.
* Target: Overall Triceps Mass (Heavy Mechanical Tension).
* Execution: Lie on a flat bench.
Hold the barbell with your hands spaced about shoulder-width apart (avoid bringing them too close together, as this can put extra stress on your wrists).Lower the bar to your lower sternum while keeping your elbows tucked at about a 45-degree angle to your body, then push the bar back up with force.
| Exercise | Primary Muscle Focus | Recommended Rep Range |
|---|---|---|
| Close-Grip Bench Press | All Three Triceps Heads | 6–8 Heavy Reps |
| Triceps Rope Pushdown | Lateral & Medial Heads | 12–15 Controlled Reps |
| Incline EZ-Bar Skullcrusher | Long Head (Overhead Stretch) | 8–12 Reps |
| Weighted Bench Dips | Medial & Lateral Heads | 10–12 Reps |
6.
Incline EZ-Bar Skullcrusher (Lying Triceps Extension)
The long head of the triceps only fully stretches when the arms are overhead or extended behind the torso.
Performing skullcrushers on an incline bench enhances this stretching effect.

* Target: Triceps Long Head.
* Execution: Lie back on a flat or slightly inclined bench, holding an EZ-bar above your chest.
Position your upper arms slightly angled backward toward your head (not vertical), then bend your elbows to lower the bar toward the top of your head.Return to the starting position.
