How to perform Reverse Flyes
- To begin, lie down on an incline bench with the chest and stomach pressing against the incline. Have the dumbbells in each hand with the palms facing each other (neutral grip).
- Extend the arms in front of you so that they are perpendicular to the angle of the bench. The legs should be stationary while applying pressure with the ball of your toes. This is the starting position.
- Maintaining the slight bend of the elbows, move the weights out and away from each other (to the side) in an arc motion while exhaling. Tip: Try to squeeze your shoulder blades together to get the best results from this exercise.
- The arms should be elevated until they are parallel to the floor.
- Feel the contraction and slowly lower the weights back down to the starting position while inhaling.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Shoulders (primary): raises and rotates the arms and drives everything overhead.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the ribs down and the glutes tight so the lower back doesn't arch to 'help' the weight up.
- Each side works on its own, so match the depth and speed of both arms and don't let the stronger side take over.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Breathe out on the effort and in on the return, keeping one steady rhythm across the set.
Common mistakes
- Pressing with the lower back arched instead of a braced, stacked torso.
- Letting the dumbbells drift apart or clang together at the top instead of controlling the path.
- Chasing weight jumps before the current load feels solid on every rep.
