Setup
- Set both pulleys to shoulder height or slightly above.
- Stand centered and grab the left cable with your right hand and the right cable with your left hand, crossing the cables in front of you.
- Step back until the weights rise slightly off the stack and assume a stable, staggered stance with your chest up.
- Hold the cable ends or small handles with a neutral grip and keep a slight bend in your elbows.
How to do it
- Exhale and pull your hands out and back in a wide horizontal arc until your arms are nearly parallel with your shoulders.
- Maintain a soft, fixed bend in the elbows throughout the entire range of motion to ensure the shoulders do the work.
- Inhale and slowly return to the starting position under control, stopping just before the weight plates touch the stack.
- Maintain a 2-1-2-0 tempo: 2 seconds to pull, 1 second pause at the peak, and 2 seconds to return.
Form checklist
- Keep your elbows high and in line with your shoulders throughout the movement.
- Avoid shrugging your shoulders toward your ears; keep your shoulder blades depressed.
- Maintain a stationary torso and avoid leaning back or using momentum to swing the weight.
- Ensure the movement occurs strictly at the shoulder joint, not by extending the elbows.
Pro tips
- Focus on 'pushing' your hands toward the side walls rather than just pulling them back to maximize rear delt recruitment.
- To isolate the rear delts further, stop the movement just before your shoulder blades fully retract to keep the tension off the rhomboids.
- Lead the movement with the back of your hands to ensure the posterior deltoid is the primary mover.
Make it harder
- Add a 3-second isometric hold at the point of peak contraction on every rep.
- Perform a slow eccentric phase, taking 4-5 seconds to return the cables to the starting position.
Frequently asked
- What muscles does the cable cross-over reverse fly work?
- The cable cross-over reverse fly primarily targets the deltoids, and also works the rhomboids as secondary muscles.
- What equipment do you need for the cable cross-over reverse fly?
- The cable cross-over reverse fly uses cable.
- Is the cable cross-over reverse fly good for beginners?
- The cable cross-over reverse fly is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
