ALTERNATING DUMBBELL CURL
Biceps Strength and Symmetry
Primary Muscles
Exercise Description
Stand with feet shoulder-width apart, holding dumbbells. Curl one weight up with a supinating motion, then lower it as you raise the other. Keep elbows close and back straight throughout.
How To Perform
Stand tall with your feet shoulder-width apart, holding a dumbbell in each hand at your sides with palms facing in.
Engage your core and keep your elbows close to your torso as you curl one dumbbell upward, rotating (supinating) your wrist so the palm faces your shoulder at the top.
Pause briefly with the biceps fully contracted, then lower the dumbbell under control until your arm is fully extended.
As you lower the first dumbbell, begin curling the other arm and repeat, alternating sides for the desired reps.
Expert Tips
Keep elbows pinned - Minimize shoulder involvement by keeping elbows close to your body to better isolate the biceps.
Avoid swinging - Use a controlled tempo and brace your core to prevent momentum from taking over.
Choose appropriate weight - Start lighter to master technique, then increase gradually to maintain full range of motion.
Fully extend the arm - Achieve a full stretch at the bottom without locking the elbow to maximize the range of motion.
Vary the setup when ready - Progress with tempo work, incline curls, or seated variations for more control and stimulus.
Common Mistakes
Using too much weight - Excess load leads to poor form and momentum, reducing biceps activation.
Swinging the torso - Leaning back or using hips shifts tension away from the biceps and stresses the lower back.
Not extending fully - Cutting the range short limits stretch and total muscle recruitment.
Elbows drifting forward - Letting elbows travel turns the curl into a front raise and reduces isolation.
Info – Alternating Dumbbell Curl
Maintain proper form by keeping your elbows close to your body and avoiding swinging. Engage your core to eliminate momentum. Start with lighter weights to focus on technique, then increase gradually as you gain strength. Fully extend the arm at the bottom for a complete range of motion. Seated versions can help with control, while variations like tempo work or incline curls increase difficulty and mind–muscle connection.
