Incline Bench Rotating Grip Dumbbell Rear Delt Fly

How to do the Incline Bench Rotating Grip Dumbbell Rear Delt Fly

1. 1Stand with your feet shoulder-width apart and hold a dumbbell in each hand, palms facing inwards.
2. 2Bend your knees slightly and hinge forward at the hips, keeping your back straight and chest up.
3. 3Raise your arms out to the sides, keeping a slight bend in your elbows, until they are parallel to the floor.
4. 4Rotate your arms so that your palms are facing downwards.
5. 5Slowly lower your arms back to the starting position.
6. 6Repeat 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.
