@iron.mike.en: This is why the pec deck butterfly is one of the best chest builders out there. Shoulder adduction gives you a huge moment arm, allowing a deep stretch and a full contraction of all chest fibers. That means better alignment, better tension, and more effective reps. Most people don’t realize this also hits the upper chest extremely well, often better than many incline presses. 👉🏾 Do you feel your chest more in fly movements or presses? #chestday #musclegrowth #hypertrophy #GymTok #fitnesseducation
