Dumbbell Flyes: How to Do It, Muscles Worked

Last updated 26 July 2026

What muscles does the Dumbbell Flyes work?

The Dumbbell Flyes primarily targets the chest, with no listed secondary muscles in the dataset. It's classified as a beginner-level strength movement using dumbbell.

What are the most common Dumbbell Flyes mistakes?

• Cutting the stretch short at the bottom instead of feeling a full stretch across the chest.
• Letting the shoulders roll forward instead of keeping the chest up through the movement.
• Bending the elbows into a press instead of keeping a fixed, slight elbow bend through the arc.
• Using a weight heavy enough that the shoulder joint — not the chest — ends up limiting the set.

How should I program the Dumbbell Flyes — sets, reps and frequency?

As a single-joint isolation exercise, it responds well to a higher 10-15 reps for 2-4 sets, usually taken close to muscular failure. It tolerates higher frequency than a heavy compound lift — twice a week for the same muscle group is common. Add small amounts of weight or an extra rep once every working set can be completed with good form — the same progressive overload principle behind every strength exercise in the library.

How to do the Dumbbell Flyes, step by step:

1. Step 1. Lie down on a flat bench with a dumbbell on each hand resting on top of your thighs. The palms of your hand will be facing each other.
2. Step 2. Then using your thighs to help raise the dumbbells, lift the dumbbells one at a time so you can hold them in front of you at shoulder width with the palms of your hands facing each other. Raise the dumbbells up like you're pressing them, but stop and hold just before you lock out. This will be your starting position.
3. Step 3. With a slight bend on your elbows in order to prevent stress at the biceps tendon, lower your arms out at both sides in a wide arc until you feel a stretch on your chest. Breathe in as you perform this portion of the movement. Tip: Keep in mind that throughout the movement, the arms should remain stationary; the movement should only occur at the shoulder joint.
4. Step 4. Return your arms back to the starting position as you squeeze your chest muscles and breathe out. Tip: Make sure to use the same arc of motion used to lower the weights.
5. Step 5. Hold for a second at the contracted position and repeat the movement for the prescribed amount of repetitions.
