Excessive Shoulder Movement

Allowing the shoulders to shrug or lift off the bench reduces the isolation on the biceps. This often indicates the weight is too heavy, leading to recruitment of the anterior deltoids and upper traps, diminishing the bicep's work and potentially causing shoulder strain.

Incomplete Range of Motion

Failing to fully extend the arms at the bottom or fully contract the biceps at the top limits the muscle's stretch and peak contraction. This reduces the overall effectiveness of the exercise for muscle hypertrophy and strength development.

Swinging the Dumbbells

Using momentum by swinging the dumbbells, especially at the start of the concentric phase, takes tension away from the biceps. This reduces muscle activation and increases the risk of injury to the elbow or shoulder joints due to uncontrolled movement.
