How to do it
- Attach a single handle to the low pulley of a cable stack and select your weight.
- Take the handle in one hand and turn to face away from the machine.
- Raise the working arm overhead so the upper arm sits beside your head.
- Bend the elbow to let the handle travel down behind your head under control.
- Extend the elbow to press the handle back overhead, stopping short of a hard lockout.
- Complete the set, then swap hands and repeat on the other side.
Common mistakes
- Letting the upper arm swing forward and back, which turns the lift into a shoulder movement.
- Snapping into lockout, which unloads the triceps and irritates the elbow.
- Standing too close to the stack, so the cable angle pulls the arm out of position.
- Leaning far forward to shift the weight, which recruits the torso rather than the arm.
