Setup
- Stand with your back to a barbell resting on a power rack or the floor.
- Grip the bar with an overhand grip (palms facing away from your body) slightly wider than shoulder-width.
- Lift the bar and stand tall with your feet shoulder-width apart and a slight bend in your knees.
- Position the bar so it hangs at arm's length behind your glutes with your chest out and shoulders back.
How to do it
- Exhale and shrug your shoulders straight up toward your ears as high as possible without bending your elbows.
- Hold the peak contraction for one second, focusing on squeezing your shoulder blades together.
- Inhale as you slowly lower the weight back to the starting position using a controlled 2-second eccentric tempo.
- Maintain a very slight forward lean if necessary to allow the bar to clear your glutes during the movement.
Form checklist
- Keep your arms completely straight throughout the set; do not use your biceps to pull the weight.
- Move the shoulders strictly vertically; avoid the common mistake of rolling the shoulders in a circular motion.
- Keep your neck neutral and chin tucked; do not thrust your head forward as you shrug.
- Ensure your core is braced to prevent your lower back from arching excessively.
Pro tips
- Imagine trying to touch your traps to your ears to ensure a full range of motion.
- If the bar catches on your glutes, lean your torso forward by 5-10 degrees to create a clear vertical path for the barbell.
- Use lifting straps for heavier sets so that your grip strength doesn't become the limiting factor for trap development.
Make it harder
- Implement a 3-second isometric hold at the top of every repetition to maximize motor unit recruitment.
- Perform '1.5 reps' by shrugging to the top, lowering halfway, shrugging back to the top, and then lowering all the way down.
