Hinging forward and pulling one handle across your body turns the usual standing cable fly into a stricter chest movement: the bent-over stance takes momentum out of the rep, and the free hand braced on your thigh keeps the torso from rotating. Work light, one arm at a time, chasing a full squeeze across the chest rather than load.

How to do the Single Arm Bent Over Cable Fly

  1. Stand with your feet shoulder-width apart, facing a cable machine.
  2. Grasp the handle with one hand and step back to create tension on the cable.
  3. Bend forward at the waist, keeping your back straight and your core engaged.
  4. Extend your arm out to the side, parallel to the ground, with a slight bend in your elbow.
  5. Slowly bring your arm back to the starting position, maintaining control throughout the movement.
  6. Repeat for the desired number of repetitions, then switch sides.

Tip: Imagine hugging a barrel rather than pushing a weight.

Muscles worked

Primary

Pectorals · Chest

On chest flies and cable crossovers the pecs pull the arms together in an arc and should feel a deep stretch at the bottom and a hard squeeze at the top.

Secondary

  • DeltsRear delt flies work the back of the shoulder as the arms swing wide, and the front delt assists on any chest fly.
  • Traps

Common mistakes

  • Elbows bending as you tirethis turns a fly into a press; set the elbow angle at the start and keep it constant for the whole set.
  • Going too heavyflies are a stretch and squeeze movement, not a strength lift; you should be able to pause at the bottom without the shoulders rolling forward.
  • Stopping short of the stretchlet the arms open until you feel the chest or rear delts lengthen, then bring them back under control.
  • Not squeezing at the finishthe last few inches are where the muscle shortens most, so hold the contraction for a count before opening again.

Sets, reps and where it fits

Flies are an isolation movement for after the pressing or rowing is done. Pair a cable crossover with a cable rear delt fly on the same station, or dumbbell chest flies with dumbbell rear delt flies on the same bench.
