How to perform the Single-Arm Cable Shrug
- Attach a single handle to a low pulley, take it in one hand, and stand side-on or facing the stack with the arm straight.
- Working one side against the cable gives constant tension and lets you brace the trunk against the pull.
- Let the cable draw the shoulder down into a full stretch at the bottom.
- Elevate that shoulder straight up toward the ear, resisting the cables downward line of pull.
- Squeeze the trap at the top, then lower under control against the constant tension.
- Keep the neck neutral and the torso upright rather than leaning to help the shoulder rise.
Suggested working range: 12–20 reps. Default progression: double progression.
Common mistakes
- •Leaning the torso to help the shoulder rise instead of bracing and shrugging cleanly.
- •Letting the cable drag the shoulder down fast rather than controlling the descent.
- •Rolling the shoulder backward instead of elevating it straight up.
- •Bending the elbow to assist the cable rather than isolating the trap.
