Start kneeling beside a bench, bracing yourself with one hand and holding a dumbbell in the other. Rest your forearm flat on the bench with the weight extended over the edge, then extend your wrist to raise the dumbbell and lower it back down with control.
Select a weight that facilitates smooth, regulated movements. Prioritize correct form over lifting a heavier load. Ensure a stable forearm placement on the bench for optimal range of motion. This exercise is particularly effective for targeting the brachioradialis muscle. You can perform this unilaterally or with both arms at the same time.
