📋 How to Do?
- Bend at the hips with a flat back, knees slightly bent, holding dumbbells with palms facing in and core braced for stability.
- Raise your arms out to the sides in a wide arc, squeezing rear delts and rhomboids at the top for peak contraction.
- Lower the weights slowly to the starting position, inhaling and resisting to maintain tension.
- Perform 3 sets of 12-15 reps, focusing on external rotation for full activation.
Hinge with a flat back and braced core for rear delt flies, using light weights to isolate without momentum, and emphasize external rotation for posture benefits. Essential for balance—avoid if lower back issues; opt for seated variations and warm up with band pull-aparts.
💪 Working Muscles
Primary: Deltoids (posterior head for horizontal abduction and external rotation); Secondary: Rhomboids (scapular retraction during fly); Trapezius (mid for rear shoulder pull)
Equipment Needed: Dumbbells or cable machine
Difficulty: Intermediate
✨ Benefits
Rear delt flies prevent rounded shoulders and improve posture through scapular retraction in shoulder balance workouts. They enhance pull strength for rows and pulls while boosting metabolic conditioning. Achieve 25% better posterior delt activation in 6 weeks.
🔥 Burned Calories
Burns Approx. 40-60 kcal per 10 min at moderate intensity
Metabolic Impact: Low to moderate, great for rear shoulder balance
Common Mistakes
- Rounding the back during the hinge, which strains the spine and compromises form.
- Using heavy weights that cause arm swinging, shifting load to traps over rear delts.
- Failing to squeeze rear delts at the top, resulting in upper back dominance instead.
