Neutral Grip Machine Rear Delt Fly

How to do the Neutral Grip Machine Rear Delt Fly

1. 1Adjust the seat height and position yourself on the machine with your chest against the pad and your feet flat on the floor.
2. 2Grasp the handles with a parallel grip, palms facing each other, and keep your arms slightly bent.
3. 3Exhale and squeeze your shoulder blades together as you pull the handles back and outward, away from your body.
4. 4Pause for a moment at the peak contraction, then inhale and slowly return to the starting position.
5. 5Repeat for the desired number of repetitions.

Tip: Imagine hugging a barrel rather than pushing a weight.

Muscles worked

Common mistakes

• Elbows bending as you tire — this turns a fly into a press; set the elbow angle at the start and keep it constant for the whole set.
• Going too heavy — flies are a stretch and squeeze movement, not a strength lift; you should be able to pause at the bottom without the shoulders rolling forward.
• Stopping short of the stretch — let the arms open until you feel the chest or rear delts lengthen, then bring them back under control.
• Not squeezing at the finish — the last few inches are where the muscle shortens most, so hold the contraction for a count before opening again.

Where it fits in a workout

Flies are an isolation movement for after the pressing or rowing is done. Pair a chest fly with a rear delt fly for a balanced superset.

Variations and alternatives

When to talk to someone

• Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
• Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
• Pregnant: ask your obstetric care provider which exercise suits you.
