Dumbbell Reverse Fly: How to Do It & Muscles Worked

The dumbbell reverse fly is an exercise that targets the rear deltoids, with secondary emphasis on the trapezius and rhomboids. It is performed by hinging at the hips, keeping the back straight, and lifting dumbbells out to the sides in a controlled manner.

How to do the dumbbell reverse fly

  1. Step 1: Stand with your feet shoulder-width apart and hold a dumbbell in each hand.
  2. Step 2: Bend your knees slightly and hinge forward at the hips, keeping your back straight.
  3. Step 3: Extend your arms straight down in front of you, palms facing each other.
  4. Step 4: Keeping a slight bend in your elbows, raise your arms out to the sides until they are parallel to the ground.
  5. Step 5: Pause for a moment at the top, then slowly lower your arms back down to the starting position.
  6. Step 6: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the dumbbell reverse fly by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
