Movement overview

The Dumbbell Alternate Supinated Curl is an isolation exercise targeting the biceps brachii. This exercise involves curling a dumbbell with a supinated (palms up) grip, alternating arms, to enhance muscle symmetry and strength in the upper arm.

Step-by-step cues

1. Stand upright with a dumbbell in each hand, arms fully extended by your sides and palms facing forward.
2. Keep your elbows close to your torso and maintain a straight back throughout the movement.
3. Curl the right dumbbell by flexing your elbow while keeping your palm facing up.
4. Continue lifting until your bicep is fully contracted and the dumbbell is at shoulder level.
5. Pause briefly at the top of the movement, squeezing your bicep.
6. Slowly lower the dumbbell back to the starting position.
7. Repeat the movement with your left arm while keeping the right arm stationary.
8. Continue alternating arms for the desired number of repetitions.

Technical tips

• Focus on controlled movements to maximize muscle engagement and minimize momentum.
• Avoid swinging your body or using your shoulders to lift the weights; isolate the biceps by keeping elbows stationary.
• Exhale as you lift the dumbbell and inhale as you lower it back down.
• Ensure a full range of motion by fully extending your arms at the bottom of each rep.
• Start with lighter weights to perfect form before progressing to heavier dumbbells.
