dumbbell seated alternate hammer curl on exercise ball

The dumbbell seated alternate hammer curl on an exercise ball is a biceps-focused exercise that also engages the forearms and core due to the instability of the exercise ball. It involves curling dumbbells alternately while seated on an exercise ball, which requires additional balance and coordination.
