Behind-the-Back Cable Shrug

What is the Behind-the-Back Cable Shrug?

The behind-the-back cable shrug is a traps isolation performed with a low cable running up behind the body, shrugging the shoulders straight up against constant tension. Holding the cable behind you keeps the torso upright and draws the shoulders back as they elevate, and the cable keeps steady pull through the whole range, combining the upper-trap bias of a behind-the-back hold with constant-tension loading.

Muscles worked

Primary: Traps

The upper trapezius is the target, elevating the shoulder blades toward the ears against the cable behind the body while the shoulders stay drawn back, against constant tension.

Secondary: Forearms

The forearms grip the handle or bar behind the body to hold the load through the set, since the arms hang straight.

How to perform the Behind-the-Back Cable Shrug

1. Stand facing away from a low pulley with a bar or handle held behind the glutes, arms straight.
2. The behind-the-back cable line pulls the shoulders back and down, loading the upper traps with constant tension.
3. Step forward to load the cable and let it draw the shoulders into a stretch behind the body.
4. Elevate the shoulders straight up toward the ears while keeping the chest tall and the arms straight.
5. Squeeze the traps at the top, then lower under control against the cables constant pull.
6. Keep the neck neutral and avoid rolling the shoulders, since the load already sits behind you.

Suggested working range: 12–20 reps. Default progression: double progression.

Mechanics

A single-joint isolation on a cable behind the body: the shoulder blades elevate and depress while the arms hang straight behind the glutes, and the cable line keeps tension on the traps across the whole range, including the top. As an isolation the behind-the-back position draws the shoulders back and keeps the shrug vertical, while the cable maintains the constant load free weights lose at the top.

Form cues

• •Set a low pulley, face away from the stack, and hold the handle behind your glutes with straight arms.
• •Step forward until you feel constant tension, then shrug the shoulders straight up toward the ears.
• •Keep the shoulders drawn back and pause to squeeze at the top before lowering under control.
• •Lower to a full stretch rather than letting the cable pull the shoulders down fast.

Common mistakes

• •Letting the bar drift off the back of the body so the shoulders round forward.
• •Rolling the shoulders in a circle rather than shrugging straight up.
• •Jutting the head forward and straining the neck under the constant tension.
• •Bending the elbows to help lift instead of keeping the arms straight.

Variations & alternatives

• •Cable shrug: a front or side cable shrug with constant tension in a neutral position.
• •Behind-the-back barbell shrug: a free-weight behind-the-back hold that goes lightest at the top.
• •Single-arm cable shrug: one side at a time for a focused peak contraction.
• •Dumbbell shrug: dumbbells at the sides for a natural range with less setup.

Programming: sets, reps & when to use it

Program behind-the-back cable shrugs as a traps accessory in the library’s 12–20 rep range, where the constant tension and the behind-the-back position reward a controlled tempo and a hard squeeze at the top. They combine an upper-trap bias with constant loading, making them a strong finisher after heavier shrugs. Set the pulley low and step forward to load the range. A few sets suffice.
