Barbell Shrug Behind The Back
This shrug variation moves the bar behind your body instead of in front, which changes the angle your traps pull from and adds a bit more forearm and mid-back involvement to hold the bar steady. You lift your shoulders straight up while the bar hangs behind your glutes, then lower back down. It's a useful variation for lifters whose traps have plateaued on the standard front shrug, though it asks more of your shoulder mobility to set up.
Why it works
Moving the bar behind your body changes the angle of pull on the traps slightly compared to a front shrug, which is why some lifters feel a different part of the muscle working. Holding the bar in that reached-back position also demands more from your forearms just to maintain the grip, and your middle back has to work a bit harder to keep the bar from swinging away from your body during the lift.
Set up
- Stand holding the barbell behind your body, arms straight down, with an overhand grip roughly shoulder width.
- Keep your torso upright and your shoulders relaxed before the first rep.
- Check that the bar hangs close to your glutes rather than swung far out behind you.
How to do it
- Lift your shoulders straight up toward your ears, keeping your elbows locked.
- Avoid pulling the bar away from your body as you shrug.
- Pause briefly at the top of the shrug.
- Lower your shoulders back down under control.
- Keep the bar close to your body through the entire rep.
- Reset your grip between reps if your forearms start to fatigue before your traps do.
Form cues
- Bar stays close to your glutes, no swinging it out behind you.
- Straight up and down, no rolling the shoulders.
- Elbows locked, only the shoulder girdle moves.
- Pause at the top before lowering.
Breathing: Exhale as you lift your shoulders up, inhale as you lower them back down.
Common mistakes
Rounding the shoulders forward to reach the bar into position behind the back.
Fix: Only attempt this variation if you can hold the bar behind your body with your shoulders relaxed and upright.
Letting the bar swing away from the body during the lift.
Fix: Keep your wrists close to your glutes throughout the movement instead of letting the bar drift backward.
Using a heavier load than the standard front shrug simply because it feels different.
Fix: Start lighter than your front shrug weight until you know how your shoulders handle the behind-the-back position.
Letting grip fatigue cut the set short before the traps are worked.
Fix: Use lifting straps once grip becomes the limiting factor rather than the traps.
How to program it
- This is a lighter accessory variation, so once or twice a week alongside your main pulling work is enough, especially while your shoulders adapt to the position.
- Two or three sets of 12 to 15 reps at a lighter load than your front shrug is a sensible starting point.
- Save it for after your main back or pulling lift, as a finishing accessory rather than the first exercise of a session.
- If your shoulders feel stiff behind your back, the standard front shrug is a perfectly good substitute; there's no need to force this variation.
Safety notes
- Only load this movement if you can comfortably hold the barbell behind your body without rounding your shoulders forward to reach it.
- Skip the behind-the-back position on days your shoulders feel tight, and use the standard front shrug instead.

Frequently asked questions
How many sets of barbell shrug behind the back should I do?
Two or three sets of 12 to 15 reps at a lighter load than your standard front shrug is a good amount, once or twice a week.
Is the behind-the-back shrug better than the regular shrug?
Not necessarily better, just different. It works the traps from a slightly different angle and adds some forearm demand, but it asks more of your shoulder mobility. Many lifters do fine sticking with the front version entirely.
Why does the behind-the-back shrug feel awkward on my shoulders?
Reaching the bar behind your body needs decent shoulder mobility. If it feels tight or forces your shoulders to round forward, stick with the standard front shrug instead.
What's the difference between this and a regular barbell shrug?
The bar position is the only real difference: behind your body here versus in front on the standard version. Both isolate the traps by keeping the elbows locked and lifting the shoulders straight up.
