Stacking three modifiers, an incline set on a stability ball, one working arm, and a cable's sideways pull, makes this fly mostly a trunk-control drill that happens to load the chest. The single cable drags you toward the machine for the entire set; use a light stack and save it for days when balance work matters more than chest volume.

How to do the Incline Stability Ball Single Arm Cable Fly

  1. Sit on an exercise ball with your feet flat on the ground and your back against an incline bench.
  2. Hold a cable handle in one hand with your arm extended and palm facing inward.
  3. Keeping a slight bend in your elbow, slowly lower your arm out to the side until your hand is in line with your shoulder.
  4. Pause for a moment, then squeeze your chest muscles to bring your arm back to the starting position.
  5. Repeat for the desired number of repetitions, then switch arms.

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.
  • Triceps

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.
