How to perform the Behind-the-Back Barbell Shrug
- Stand with a barbell held behind the glutes, taking a shoulder-width overhand grip with the arms straight.
- Holding the bar behind the body pulls the shoulders back, biasing the upper traps while opening the chest.
- Let the bar hang against the back of the thighs so the traps stretch at the bottom.
- Elevate the shoulders straight up toward the ears, keeping the bar close to the body and the arms straight.
- Squeeze the traps at the top with the chest tall, then lower under control to the stretch.
- Keep the neck neutral and avoid rolling the shoulders, since the bar path is already behind you.
Suggested working range: 12–20 reps. Default progression: double progression.
Common mistakes
- •Letting the bar drift away from the back of the thighs so the shoulders round forward.
- •Rolling the shoulders instead of shrugging them straight up behind the body.
- •Jutting the head forward and straining the neck under load.
- •Bending the elbows to help lift the bar rather than keeping the arms straight.
