Variations of the biceps curl with the expander
Similar to biceps curl with weights, the expander training can be varied. In classic biceps curl, the palms of the hands are permanently upwards during contraction. To increase the load during the movement, the palms can face each other in the starting position and be rotated outwards during the overcoming (concentric) phase.
Furthermore, the palms can point towards each other during the entire contraction. The biceps curl with the expander can be trained alternately, or both arms simultaneously. In both forms, however, the upper body template must be maintained during the entire movement.
