Movement overview

The Dumbbell Incline Alternate Supinated Curl is an isolation exercise targeting the biceps brachii. Performed on an incline bench, it emphasizes the long head of the biceps by maintaining a supinated (palm-up) grip throughout the movement. This exercise helps in developing peak bicep strength and size while also engaging the forearms.

Step-by-step cues

1. Set an incline bench to a 30-45 degree angle.
2. Sit on the bench with your back firmly against the pad and feet flat on the floor.
3. Hold a dumbbell in each hand with your arms fully extended and palms facing forward (supinated grip).
4. Keep your elbows close to your torso and curl one dumbbell towards your shoulder by contracting your biceps.
5. Pause briefly at the top of the movement, ensuring maximum contraction.
6. Slowly lower the dumbbell back to the starting position.
7. Repeat the movement with the opposite arm.
8. Continue alternating arms for the desired number of repetitions.

Technical tips

• Maintain a controlled motion throughout to maximize muscle engagement.
• Avoid swinging or using momentum to lift the weights; focus on isolating the biceps.
• Keep your elbows stationary and close to your sides to prevent shoulder involvement.
• Exhale as you curl the weight up and inhale as you lower it back down.
• Ensure your back remains pressed against the bench to prevent arching.
• Use a lighter weight if you struggle to maintain proper form.
