Can you recommend any other unilateral trap exercises to complement single-arm shrugs?

There are several other great unilateral trap exercises that can complement single-arm dumbbell shrugs:

1. Single-Arm Farmer's Walks
   Holding a heavy dumbbell or kettlebell at your side and walking for distance or time engages the traps isometrically to help stabilize the load.

2. Single-Arm Farmer's Carry Shrugs
   Add a shrugging motion at the end of each Farmer's Walk step to really fatigue the working trap.

3. Single-Arm Seated Dumbbell Shrugs
   Performing seated shrugs with one arm removes leg drive and forces the traps to do more work.

4. Single-Arm Bent-Over Dumbbell Rows
   Focus on really squeezing the trap at the top of each single-arm row rep.

5. Single-Arm Upright Rows
   The upright pulling motion targets the traps along with the deltoids.

6. Single-Arm Dumbbell Reverse Flyes
   This rear delt exercise also involves trap activation to stabilize the scapula.

7. Single-Arm Dumbbell Face Pulls
   Pulling the weight straight back towards your face emphasizes trap engagement.

The key is to alternate which arm is working from set to set to ensure balanced trap development. Start light, focus on form, and gradually increase the weight over time. Mixing in these unilateral trap exercises can be an effective way to complement your single-arm shrug work.
