In this brief instructional segment, the presenter delivers three concise cues to improve the form of a dumbbell hammer curl. First, instead of lifting the weight straight up, the lifter should curl the dumbbell slightly inward toward the body, without crossing the midline. Second, the shoulders must stay pulled back and down, avoiding any rounding or forward hunch. Third, the elbows should remain stationary, not moving forward; the curl should stop at chest level before lowering. These tips aim to maximize biceps engagement while minimizing shoulder and elbow strain.
