Dumbbell Fly: How to Do It & Muscles Worked
The dumbbell fly is a chest exercise performed lying on a bench, using dumbbells to stretch and contract the pectoral muscles through a wide arc motion.
How to do the dumbbell fly
- Step 1: Lie flat on a bench with a dumbbell in each hand, palms facing each other.
- Step 2: Extend your arms straight up over your chest, with a slight bend in your elbows.
- Step 3: Keeping a slight bend in your elbows, lower your arms out to the sides in a wide arc until you feel a stretch in your chest.
- Step 4: Pause for a moment, then reverse the movement and bring the dumbbells back up to the starting position.
- Step 5: Repeat for the desired number of repetitions.
Sets, reps and programming
| 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.
