Adding a grip rotation to the chest-supported rear delt fly, palms turning from facing each other to facing down as the arms rise, changes how the upper arm finishes the arc. Compared with the fixed-grip incline bench version it needs lighter dumbbells and more patience; rush the turn and the whole rep becomes a swing.
How to do the Incline Bench Rotating Grip Dumbbell Rear Delt Fly
- Stand with your feet shoulder-width apart and hold a dumbbell in each hand, palms facing inwards.
- Bend your knees slightly and hinge forward at the hips, keeping your back straight and chest up.
- Raise your arms out to the sides, keeping a slight bend in your elbows, until they are parallel to the floor.
- Rotate your arms so that your palms are facing downwards.
- Slowly lower your arms back to the starting position.
- Repeat for the desired number of repetitions.
Tip: Imagine hugging a barrel rather than pushing a weight.

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.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Muscle growth | 3–4 × 10–15 | 60–90 s |
| Endurance / finisher | 2–3 × 15–20 | 45 s |
| Strength | Not ideal — pick a compound lift for the same muscle | — |
Flies are an isolation movement for after the pressing or rowing is done. Pair a cable crossover with a cable rear delt fly on the same station, or dumbbell chest flies with dumbbell rear delt flies on the same bench.
