Movement overview

The Single Dumbbell Curl is an isolation exercise targeting the biceps brachii. It involves curling a single dumbbell with one hand, emphasizing unilateral strength and muscle balance. This exercise helps in developing the peak of the bicep and improving arm symmetry.

Step-by-step cues

1. Stand upright with feet shoulder-width apart, holding a dumbbell in one hand with an underhand grip.
2. Keep your elbow close to your torso and your palm facing forward.
3. Exhale as you curl the dumbbell upward by bending your elbow, keeping your upper arm stationary.
4. Continue lifting until your bicep is fully contracted and the dumbbell is at shoulder level.
5. Hold the contraction for a moment, then inhale as you slowly lower the dumbbell back to the starting position.
6. Repeat for the desired number of repetitions before switching to the other arm.

Technical tips

• Maintain a controlled motion throughout the exercise to maximize muscle engagement and reduce injury risk.
• Avoid swinging or using momentum to lift the dumbbell; focus on isolating the bicep muscle.
• Keep your wrist straight and avoid bending it during the curl to prevent strain.
• Ensure your elbow remains fixed at your side to target the bicep effectively.
• Start with a lighter weight to perfect your form before progressing to heavier dumbbells.
