Description
An isolation exercise that targets the rear deltoids. The exerciser stands and bends over slightly, then lifts the weights to the sides keeping the elbows slightly bent.
How to Do Dumbbell Rear Fly
- 1Setup
Stand with feet hip-width apart, holding a dumbbell in each hand with a neutral grip. Hinge forward at your hips until your torso is nearly parallel to the floor, allowing the dumbbells to hang straight down.
- 2Setup
Maintain a slight bend in your elbows and keep your core engaged, with a neutral spine throughout the bent-over position.
- 3
Exhale as you raise the dumbbells out to the sides in an arc, leading with your elbows, until your arms are parallel to the floor. Focus on squeezing your shoulder blades together at the top.
- 4
Inhale as you slowly lower the dumbbells back to the starting position with control, resisting gravity. Avoid letting the weights drop or swing.
- 5
Ensure your elbows remain slightly bent throughout the movement and avoid shrugging your shoulders towards your ears.
Tips
- Focus on leading the movement with your elbows and squeezing your shoulder blades together at the top to effectively target the rear deltoids.
- Maintain a slight bend in your elbows throughout the entire range of motion to protect your elbow joints and keep tension on the target muscles.
- Control both the upward and downward phases of the lift; avoid using momentum to swing the weights up or letting them drop quickly.
- Keep your head in a neutral position, in line with your spine, to prevent neck strain and maintain proper posture during the bent-over position.
Common Mistakes
- ×Rounding your back instead of maintaining a neutral spine can lead to injury; ensure you hinge primarily at the hips and keep your chest proud.
- ×Using momentum to swing the dumbbells up rather than controlled muscle contraction reduces rear deltoid activation; lower the weight and focus on a slow, deliberate squeeze.
- ×Shrugging your shoulders towards your ears engages your upper traps instead of your rear delts; keep your shoulders depressed and focus on pulling the weights out to the sides.
