Train.exerciseLibrary.primaryMuscles

• Biceps brachii

Secondary muscles

• Brachialis
• Brachioradialis
• Forearm flexors

Technique

• Sit upright on a bench with a dumbbell in each hand.
• Keep the elbows close to the torso.
• Start with the arms fully extended.
• Curl the dumbbells upward by flexing the elbows.
• Squeeze the biceps at the top of the movement.
• Lower the dumbbells slowly under control.
• Maintain stable body position throughout the exercise.

Common mistakes

• Swinging the torso.
• Moving the elbows forward excessively.
• Using momentum.
• Incomplete range of motion.
• Lowering the weight too quickly.

Special recommendations

• Keep the elbows fixed beside the body.
• Focus on controlled repetitions.
• Avoid excessive weight that compromises technique.
• Use a full range of motion.

When to use

• Building biceps muscle mass.
• Improving arm strength.
• Accessory upper-body training.
• Hypertrophy-focused programs.

Consider modifications if

• Moderate elbow pain increases with loading or flexion.
• Moderate biceps or elbow discomfort limits comfortable curling range.
• Moderate wrist discomfort affects grip position.
• Proper elbow and body position cannot be maintained throughout the exercise.

In these situations, consider reducing load, adjusting technique, choosing an alternative exercise, or consulting a qualified professional.

Exercise variations

• Alternating Dumbbell Curl

  One arm moves at a time, allowing greater focus on each side.

• Hammer Curl

  Neutral grip variation that increases brachialis and forearm involvement.

• Incline Dumbbell Curl

  Performed on an incline bench. Increases stretch and long-head biceps activation.

• Concentration Curl

  Provides greater isolation and muscle focus.
