Dumbbell Curl
The Dumbbell Curl primarily works the Biceps Brachii (Long Head), Biceps Brachii (Short Head), with secondary activation of the Brachialis, Brachioradialis and stabilizer support from the Anterior Deltoid, Levator Scapulae, Rectus Abdominis, Transverse Abdominis, Trapezius (Middle), Trapezius (Upper), Wrist Flexors. It is a dumbbell isolation exercise at beginner difficulty.
The Dumbbell Curl is an beginner isolation exercise performed with dumbbell, following a flexion movement pattern. It primarily targets the Biceps Brachii (Long Head), Biceps Brachii (Short Head), with secondary engagement of the Brachialis, Brachioradialis. This is a bilateral pulling movement, engaging both sides of the body simultaneously.
Standing dumbbell curl with neutral grip allowing greater range of motion.

Muscles Worked
The Biceps Brachii (Long Head), and Biceps Brachii (Short Head) are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Brachialis, and Brachioradialis act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Anterior Deltoid, Levator Scapulae, Rectus Abdominis, and 4 other muscles act as stabilizers, maintaining joint position and postural alignment throughout the movement.

- Primary Muscle Biceps Brachii (Long Head) (biceps)
- Primary Muscle Biceps Brachii (Short Head) (biceps)
Secondary Muscles
- Secondary Muscle Brachialis (biceps)
- Secondary Muscle Brachioradialis (biceps)
Stabilizer Muscles
- Stabilizer Muscle Anterior Deltoid (shoulders)
- Stabilizer Muscle Levator Scapulae (neck)
- Stabilizer Muscle Rectus Abdominis (core)
- Stabilizer Muscle Transverse Abdominis (core)
- Stabilizer Muscle Trapezius (Middle) (back)
- Stabilizer Muscle Trapezius (Upper) (back)
- Stabilizer Muscle Wrist Flexors (forearms)
How to Perform
Preparation
- Position two dumbbells to sides, palms facing in, arms straight.
Execution
- With elbows to sides, raise one dumbbell and rotate forearm until forearm is vertical and palm faces shoulder.
- Lower to original position and repeat with opposite arm.
- Continue to alternate between sides.
Comments
- Biceps may be exercised alternating (as described), simultaneous, or in simultaneous-alternating fashion.
- When elbow is fully flexed, it can travel forward slightly, allowing forearms to be no more than vertical.
- This additional movement allows for relative release of tension in muscles between repetitions.
- Also seemechanical analysis of arm curlandquestion regarding elbow position.
Tips & Common Mistakes
- Control the eccentric phase — the lowering portion drives significant muscle development.
- Avoid momentum; focus on feeling the target muscle work through the full range.
- Full range at both ends maximizes stretch at the bottom and contraction at the top.
Programming Suggestions
Adapt your sets and reps to your training goal. As a beginner-friendly exercise, start with lighter loads and focus on form before progressing weight.
| Strength | 3–4 sets × 6–8 reps at 75–85% 1RM with 90–120 seconds rest. |
|---|---|
| Hypertrophy | 3–4 sets × 10–15 reps at 60–75% 1RM with 60–90 seconds rest. |
| Endurance | 2–3 sets × 15–25 reps at 40–60% 1RM with 30–45 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Biceps Brachii (Long Head), Biceps Brachii (Short Head)) and can be substituted based on your equipment or variation preferences.
