Cable Cross-Over Reverse Fly

Body Part: Shoulders

Muscle: Shoulders

Equipment: Cable Machine

The Cable Cross-Over Reverse Fly is a rear-shoulder and upper-back exercise performed with two cable handles crossed in front of the body. As the arms open out to the sides, the posterior deltoids, rhomboids, and traps work to move and stabilize the shoulder blades.

Cables keep tension on the rear delts through the full range, which makes light loads very effective. The elbows stay slightly bent and fixed, and the movement should look like a wide arm sweep rather than a row. Shrugging or pulling with the hands usually means the load is too heavy.

Set the pulleys around shoulder height, stand centered, and hold the opposite handles so the cables cross in front of you. Brace the torso, open the arms out and slightly back, pause when the rear shoulders are engaged, then return slowly to the crossed start position.

Use this exercise for rear-delt development, posture-focused upper-back work, or warmups before pressing and pulling. Keep the neck relaxed, shoulders down, and torso still. Adjust pulley height if the path pinches or the traps dominate.

Instructions

• Set both cable pulleys around shoulder height and attach handles.
• Stand centered between the pulleys and grab the opposite handles so the cables cross.
• Step back enough to create light tension with your arms crossed in front of you.
• Brace your core and keep a slight, fixed bend in both elbows.
• Keep your shoulders down as you open your arms out to the sides.
• Pull until the rear shoulders and upper back are engaged without shrugging.
• Pause briefly at the open position.
• Return slowly to the crossed starting position.

Tips & Tricks

• Use light weight because the rear delts do not need heavy loading to work.
• Keep the elbow bend consistent so the movement does not become a row.
• Open from the shoulders, not by pulling the wrists backward.
• Keep the neck relaxed and avoid shrugging into the traps.
• Stand tall and resist leaning back as the arms open.
• Control the return so the cables do not snap your arms forward.
• Use a slightly lower pulley height if shoulder-height cables feel pinchy.
• Pause at the open position only if you can keep the shoulders down.

Frequently Asked Questions

What muscles does the Reverse Fly target?

It mainly targets the rear shoulders, with help from the rhomboids and traps.

Should I bend my elbows?

Keep a slight bend, but avoid turning the movement into a row.

Why use cables?

Cables keep steady tension on the rear delts through the whole range.

Why are the handles crossed?

Crossing the handles creates a better starting line of pull and keeps tension on each rear delt.

How high should the pulleys be?

Shoulder height is a good starting point, but adjust slightly for comfort and rear-delt feel.

Should my shoulder blades squeeze together?

They can move naturally, but do not over-squeeze so hard that the traps take over.

Can beginners do this exercise?

Yes, with very light weight and strict control of the arm path.

What is the biggest mistake?

Using too much weight and turning the reverse fly into a bent-elbow row or shrug.
