Single-Arm Cable Rear Delt Fly
One arm across the body from the opposite pulley, opening out and back.

How to do it
Setup
Side-on, handle from the OPPOSITE pulley held across the body at shoulder height.
Steps
- Open the arm out and back at shoulder height.
- Keep the soft elbow frozen.
- Return across the body with tension.
Common mistakes
Torso rotating with the arm: square shoulders; only the arm travels. Dropping the arc: shoulder height, always. Grabbing heavy: a single rear delt moves little weight well.
Breathing
Exhale opening, inhale returning.
