http://askthetrainer.com/best-traps-exercise.html Personal Trainer Michael Behnken, MS, NASM-CPT-PES, CSCS If you want to build your traps you can look no further than shoulder shrugs. Make sure you keep your arms completely straight and lift your shoulders as high as they possibly can go. Make sure you squeeze at the top of the motion for a split second. If you have forward head posture shoulder shrugs is not the best exercise. http://AskTheTrainer.com/posture-problems.html
