How To PROPERLY Do Rear Delt Cable Flys (Cross-Arm Rear Delt Fly)

Rear delts are one of the most misunderstood and poorly trained muscles — and most people either feel this exercise in their traps, arms, or not at all.

In this video, I break down exactly how to do the Rear Delt Cable Fly (Cross-Arm Variation) properly so you can:
• Actually feel your rear delts working
• Build wider, more balanced shoulders
• Improve posture and shoulder health
• Stop wasting reps with sloppy form

You’ll learn:
• Proper cable height and setup
• Why the cross-arm position works better for rear delts
• The biggest mistakes killing rear delt activation
• Ideal range of motion and tempo
• How to avoid turning this into a trap or upper-back exercise

If your shoulders look underdeveloped from the side or back, or you struggle with shoulder discomfort, this exercise done correctly can be a game-changer.

This is how I coach rear delts with my online clients to get real, visible results — not just pumpy junk volume.
