Low-to-High Cable Fly: how to do it right
In short: Low-cable fly crossing upward, a chest isolation that loads the upper pec at the end of the contraction.
How to do it, step by step
- 1Pulleys at the floor, one handle in each hand, torso leaning slightly forward, chest high and shoulder blades squeezed.
- 2Arms semi-straight, elbows locked in a slight bend: this angle doesn't change for the whole set.
- 3Raise the hands in an arc upward, making them cross above the head.
- 4Squeeze the pecs hard for 1 second in the high crossed position, chest pushing forward.
- 5Control the return slowly, without letting the weights release the tension.
- 6Stay focused on the upper pec, not on the height of the arms.
The mistake to avoid
Don't swing your torso to raise your arms. Isolate the upper chest.
Other common mistakes
- Stopping the hands too early without crossing: you miss the most loaded zone, cross them decisively overhead.
- Bending then straightening the elbows to cheat: it turns the fly into a press, keep the elbow angle fixed.
- Releasing tension on the return: the weight drops in free fall, actively brake the lengthening phase.
- Using too heavy a weight and arching: reduce the load to hold the clean 1 s pause at the top.
Muscles worked
- Main:
- Chest
Pec major, clavicular head (upper pec): prime mover through ascending arm adduction. The sternocostal head takes part at the start of the range. The anterior delt assists discreetly, the serratus anterior stabilizes the scapula. No secondary muscle is really involved, it's targeted work.
What to replace it with
Same muscle, same part of the movement: these exercises do the same job.

Frequently asked questions
How do I do this exercise?
Pulleys at the floor, one handle in each hand, torso leaning slightly forward, chest high and shoulder blades squeezed. Arms semi-straight, elbows locked in a slight bend: that angle doesn't change. Raise the hands in an arc and cross them above the head, squeeze for 1 second, then control the return.
How high should I go?
The tension peak is at the end of the range, when your hands cross at the top: that's where the pec works the hardest. Don't stop when the hands touch, cross them decisively, as if trying to touch the opposite shoulder. The start of the movement is almost free, the end is what counts.
I don't feel anything, is that normal?
You should feel the upper pec. Don't try to raise the arms high, try to cross far, as if to touch the opposite shoulder. Really hold the second of squeeze, thinking of bringing your two pecs together, not just your hands. If you feel it in the shoulders, lower the weight and lock your elbows.
How fast should I do the movement?
Rise in control, squeeze hard for 1 second in the crossed position, then brake the return over 2 to 3 seconds without letting the weights release. It's the pause at the top and the braking that do the work, never speed.
How do I breathe?
Inhale as your hands move apart and lower, the tensioning phase. Breathe out as you rise and cross, when you squeeze the pec. Keep the abs braced throughout to lock the torso and avoid arching.
