The dumbbell shrug is a variation of the shrug and an exercise used to build trap muscle size.
Traps, being a stubborn muscle group for many, can be trained with a fairly high frequency during the week. When doing so, be sure to mix up the volume, intensity, and implements you use to train the traps.
Dumbbell shrugs can be included into your shoulder workouts, back workouts, upper body workouts, and full body workouts.
