Cable Standing Single Arm Fly
Cable Standing Single Arm Fly Exercise Description
The Cable Standing Single Arm Fly is a unilateral chest exercise that trains horizontal adduction of the shoulder using a controlled, wide arc. It emphasizes the pectoralis major, with assistance from the anterior deltoid, while the rotator cuff stabilizes the glenohumeral joint. Because the load is on one side, the trunk and hips must resist rotation and extension, encouraging strong bracing and balance. The cable’s consistent line of pull helps maintain tension through the full range and allows precise arm path control. Proper execution keeps a relatively constant elbow angle, neutral wrist, and steady scapular mechanics—setting the shoulder blade down and slightly back at the start, then allowing natural, non-shrugging protraction as the hand approaches the midline.

How To Do The Cable Standing Single Arm Fly Exercise
‘- Set a single handle on a cable at mid-chest/shoulder height.
– Stand facing away from the pulley; hold the handle in the working hand and step forward to create light tension.
– Take a staggered stance, knees softly bent; brace the abdomen and keep a neutral spine with ribs stacked over pelvis.
– Set the shoulder blade down and slightly back; keep the chest tall without flaring the ribcage.
– Start with the upper arm slightly behind the torso, elbow softly bent (about 15–30°), wrist neutral.
– Exhale gently as you sweep the arm forward in a wide arc across the chest; keep the elbow angle essentially constant.
– Finish with the hand near the sternum/midline at shoulder height; allow natural scapular protraction without shrugging.
– Pause briefly; avoid torso rotation or leaning—hips and shoulders stay square.
– Control the return, letting the shoulder blade retract smoothly; stop before the shoulder pulls forward or pinches.
– Keep the movement in the shoulder (horizontal adduction), not a press—do not increase elbow flexion to move the load.
Cable Standing Single Arm Fly Tips
‘- Set the cable handle at about mid-chest/shoulder height before you begin.
– Take a staggered stance with soft knees, then brace your abdomen to keep a neutral spine and ribs stacked over your pelvis.
– Position the shoulder blade down and slightly back with a tall chest, avoiding ribcage flare.
– Start with the upper arm slightly behind your torso, elbow softly bent around 15–30°, and wrist neutral.
– Sweep the arm forward in a wide arc across your chest while keeping the elbow angle essentially constant.
– Aim to finish with your hand near your sternum/midline at shoulder height.
– Allow natural shoulder blade protraction at the finish without shrugging the shoulder up.
– Keep hips and shoulders square, avoiding any torso rotation or leaning as you move the arm.
– Control the return, letting the shoulder blade retract smoothly and stopping before the shoulder pulls too far forward.
– Focus on moving at the shoulder joint (horizontal adduction) rather than turning it into a press by bending the elbow more.
Cable Standing Single Arm Fly Beginner Introduction
With the Cable Standing Single Arm Fly, one side of the chest works at a time while the cable supplies smooth, continuous resistance. The arm moves in a broad sweep across the front of the body, highlighting the chest muscles and involving the front of the shoulders. Small stabilizing muscles around the shoulder joint assist behind the scenes, helping the arm glide through the motion in a controlled, comfortable path.
Because the handle is held on only one side, the body naturally fights against twisting and leaning, so the core and hips are challenged to stay steady. The movement generally uses a gentle bend in the elbow and a relaxed wrist position, so the chest, not the arm, guides the action. The shoulder blade shifts from a slightly anchored position at the start to a more forward position as the hand approaches the center of the body, without excessive shrugging. This combination of chest work, shoulder control, and full-body stability makes the exercise a focused, deliberate option for cable-based upper body training.
