Shrugs are a staple in most athletes’ workouts. Why? Because you’d be hard-pressed to find someone who doesn’t want bigger and more intimidating traps. Technically called the trapezius muscle, this large muscle travels along your mid and upper spine and attaches to your shoulder, covering a large portion of your mid and upper back. When you do Shrugs, you specifically target the upper traps, which are the portion that sits just above your collarbone and moves into your neck.

But is there a better way than performing old-school Barbell or Dumbbell Shrugs? I’ve been experimenting with Shrug variations and have found the following two exercises to be quite effective for developing a set of imposing traps.
