Dumbbell Alternate Biceps Curl
Dumbbell Alternate Biceps Curl Video Guide
The Dumbbell Alternate Biceps Curl is a classic biceps curls exercise that builds upper-arm size, strength, and symmetry. Alternating biceps curls forces each arm to work independently, improving muscle engagement, balance, and mind–muscle connection. This movement targets the biceps brachii, brachialis, and brachioradialis, while also engaging the forearms and stabilising muscles of the shoulders and upper arms.
The alternating curl path allows a natural elbow flexion pattern and smooth wrist rotation, reducing strain and improving proper form. Because you lift one arm at a time, you maintain constant tension, reduce cheating, and achieve better muscle growth, especially across the upper arms. It fits into any upper-body or arm workout and is ideal for beginners and advanced lifters looking to build bigger arms with strict technique.
How to Perform the Dumbbell Alternate Biceps Curl
-
Stand with feet shoulder width apart, holding two dumbbells at your sides in a neutral grip. Keep your chest up and maintain good posture in the starting position.
-
Curl one dumbbell upward, rotating your wrist so your palms facing up by mid-curl. Keep elbows close and upper arms still.
-
Squeeze the biceps hard at the top of the curl motion and avoid swinging or leaning back.
-
Slowly lower the dumbbell through the eccentric portion until your arm is fully extended.
-
Repeat the same movement with the other arm, alternating reps with smooth, controlled motion.
-
Continue alternating arms while keeping your torso stable and tension high throughout the exercise.
GymNation Tip: Keep elbows close to the body, wrists neutral, and movement strict. Avoid swinging or using momentum. Move through a full range with smooth rotation and controlled tempo on every rep.
Personal Trainer Notes:
-
Keep elbows tight to your sides — drifting elbows reduce muscle engagement.
-
Use controlled wrist rotation for stronger activation.
-
Avoid leaning back; momentum kills tension and reduces gains.
-
Keep shoulders relaxed to prevent compensating with the upper body.
-
Alternate arms without rushing so each rep gets full attention.

Alternative Bicep Exercises
Barbell Curl
The Barbell Curl targets the biceps brachii, helping to build size and strength in the front of your upper arms. It’s a staple for arm development and grip strength. Perform it with control and full range of motion for best results.
Dumbbell Standing Biceps Curl
The Dumbbell Standing Biceps Curl targets the biceps (biceps brachii) and forearms (brachioradialis). It helps improve arm symmetry and muscle tone when done with strict form.
EZ Barbell Curl
The EZ Barbell Curl strengthens the biceps (biceps brachii) with reduced wrist strain thanks to the angled grip. It’s ideal for building strength and muscle mass with comfort.
Dumbbell Incline Biceps Curl
The Dumbbell Incline Biceps Curl stretches and strengthens the biceps (biceps brachii) through a longer range of motion. It’s great for improving peak shape and flexibility.
Dumbbell Hammer Curl
The Dumbbell Hammer Curl targets the biceps (brachialis) and forearms (brachioradialis). It builds both arm thickness and grip strength while reducing wrist strain.
Cable Curl
The Cable Curl targets the biceps (biceps brachii) with constant tension throughout the movement. It’s excellent for controlled strength and shape development.
Dumbbell Concentration Curl
The Dumbbell Concentration Curl focuses on isolating the biceps (biceps brachii) for maximum contraction and shape. It’s excellent for building definition and mind-muscle connection.
Dumbbell Zottman Curl
The Dumbbell Zottman Curl targets both the biceps (biceps brachii) and forearms (brachioradialis) in one move. It builds balanced arm strength and control.
Barbell Preacher Curl
The Barbell Preacher Curl isolates the biceps (biceps brachii) and reduces shoulder involvement, making it perfect for focused arm growth. The preacher bench supports strict form and control.
Dumbbell Alternate Biceps Curl FAQs
Primarily the biceps brachii, with strong involvement from the brachialis, forearms, and stabilising upper-arm muscles.
Yes — alternating curls improve control, reduce imbalances, and maintain tension while allowing slight rest between reps for more total volume.
Hammer curl, dumbbell concentration curl, incline curls, reverse curls, and cable curls all work the same muscle group from different angles.
Stand tall, curl one arm at a time, rotate the wrist, squeeze at the top, and lower slowly with no swing or torso movement.
Choose a weight you can perform for 8–12 strict reps per arm without using momentum. Clean reps beat heavy, sloppy curls.
Yes — they strengthen the brachioradialis and forearms, improving grip strength and arm stability.
Absolutely. It’s beginner-friendly, easy to learn, and one of the best exercises for safe, controlled arm training.
