Incline Dumbbell Fly
Muscles worked
Instructions
- 1Hold a dumbbell on each hand and lie on an incline bench that is set to an incline angle of no more than 30 degrees.
- 2Extend your arms above you with a slight bend at the elbows.
- 3Now rotate the wrists so that the palms of your hands are facing you. Tip: The pinky fingers should be next to each other. This will be your starting position.
- 4As you breathe in, start to slowly lower the arms to the side while keeping the arms extended and while rotating the wrists until the palms of the hand are facing each other. Tip: At the end of the movement the arms will be by your side with the palms facing the ceiling.
- 5As you exhale start to bring the dumbbells back up to the starting position by reversing the motion and rotating the hands so that the pinky fingers are next to each other again. Tip: Keep in mind that the movement will only happen at the shoulder joint and at the wrist. There is no motion that happens at the elbow joint.
- 6Repeat for the recommended amount of repetitions.

About Incline Dumbbell Fly
The incline dumbbell fly isolates the upper chest thanks to the bench incline, around 30-45 degrees. Arms slightly bent and elbows fixed, you open the dumbbells wide out to the sides to a marked stretch of the upper chest, then bring them back together above you in an arc. The incline emphasises the stretch and work on the upper chest, often neglected. Like any fly, it is about opening and closing the arms without bending the elbows: keep a moderate load so you do not turn it into a press or stress the shoulder. Excellent alongside the incline press, as isolation or a finisher.
check_circleBenefits
- check_circleIsolates the upper chest under stretch
- check_circleImproves definition of the upper portion
- check_circleDevelops mind-muscle feel in the chest
- check_circleThe dumbbells' natural range follows the shoulders' own path, without the fixed trajectory a bar or machine would impose.
- check_circleAn excellent finisher to accentuate the upper-chest stretch after heavier pressing work.
lightbulbExecution tips
- lightbulbSet the bench between 30 and 45 degrees
- lightbulbKeep the elbow angle fixed throughout
- lightbulbOpen until a comfortable stretch, without forcing
- lightbulbBring the arms up while squeezing the chest
- lightbulbKeep a slight, fixed bend in the elbows throughout rather than bending them more on the way down, which would turn the fly into a partial press.
warningCommon mistakes
- warningBending the arms and pressing like a press
- warningGoing too low and overstretching the shoulder
- warningChoosing too heavy a weight and losing control
- warningSetting the bench too high and taxing the shoulders
- warningLowering the dumbbells too far below shoulder level, which places the joint in excessive external rotation and increases the risk of discomfort.
tuneVariations and alternatives
- tuneFlat Bench Dumbbell Fly — shifts the emphasis toward the mid-chest by changing the bench angle.
- tuneIncline Cable Fly — replaces the dumbbells with a cable for constant tension through the full range.
- tuneIncline Dumbbell Flyes - With A Twist — adds a wrist rotation at the top to vary the contraction feel.
- tuneSingle-Arm Incline Fly — isolates one side at a time to correct an imbalance or reinforce anti-rotation bracing.
person_checkWho it's for and level
The incline dumbbell fly suits intermediate to advanced lifters who already have a pressing strength base and want an isolation exercise to fine-tune the upper chest. It requires good body awareness to control the descent without being pulled down by the dumbbells' weight, which makes it less suited to beginners, who should first build solid pressing technique before adding isolation work.
shieldSafety and precautions
Only lower the dumbbells to a comfortable stretch point, never forcing beyond what the shoulder tolerates without discomfort, and get help getting into the starting position if the dumbbells are heavy, since injuries often happen right at that moment (dumbbells in the low position, shoulders not yet stabilized). Reduce the load at the slightest sense of shoulder instability.
calendar_monthWhere to place it in your program
Place the incline dumbbell fly at the end of a chest session, after the incline press, for 3 sets of 10-15 reps with a moderate load that allows full control of the descent. It works well in a superset with a light incline press to finish the chest in depth, or occasionally as a pre-exhaustion method before a compound movement.
helpFrequently asked questions
Incline or flat fly, which to pick?
The incline targets the upper chest and the flat the mid-chest; alternate based on the area you want to build.
How many reps should I do?
Aim for 10 to 15 reps with a moderate weight, focusing on range and stretch.
Incline fly or incline press for the upper chest?
The incline press builds mass and strength (a base movement); the incline fly isolates and stretches, as a finisher. Do the press first for the bulk of the work, then the fly to target and pump the upper chest.
Should the palms face each other or turn toward the ceiling during this movement?
Keep the palms facing inward (toward each other) throughout the movement, as if hugging a large tree trunk. Rotating the wrists to turn the palms toward the ceiling at the top (as some do to 'enhance the contraction') adds unnecessary wrist torque without any proven extra benefit for the chest, and can even create joint discomfort for some lifters.
What's the advantage of the incline dumbbell fly over the cable version?
The dumbbell imposes a resistance that varies with gravity (highest in the middle of the range, lowest at the top and bottom), giving a different contraction feel than the cable, where tension stays constant thanks to the cable angle. Neither is strictly superior: they load the chest with complementary resistance profiles, which is why it's worth alternating between the two across training cycles.
Should I prefer round or hex dumbbells for this movement?
Hex dumbbells offer better stability in the starting position on the thighs, and won't roll away if you need to set them down quickly out of fatigue. Round dumbbells work just as well once in motion, but require a bit more care during setup and when putting them back down.
