In this instructional segment, Eric Roberts highlights two frequent errors people make when performing incline bicep curls. The first mistake is allowing the elbows to drift too far forward during the upward phase, which compromises shoulder positioning. He advises keeping the elbows and shoulders pulled back throughout the movement. The second mistake is cutting the range of motion short by not lowering the arms fully. Roberts stresses the importance of completing the full stretch, even if it means using lighter weight, because a complete range yields greater muscular benefit. He concludes by encouraging viewers to apply these cues in their next workout.
