@giljongkeun: 🔽3 Pec Deck Fly Mistakes You Need to Fix🔽 Still not feeling your chest on the pec deck? You might be making one of these 3 common mistakes. 1. Leaning Forward ❌ Chest contraction weakens, shoulders take over ✅ Back on pad, chest open, arms together 2. Shrugging Shoulders ❌ Traps dominate, chest activation drops ✅ Shoulders down and locked before moving 3. Elbows Dropping Down ❌ Turns into a press, inner chest shuts off ✅ Elbows at chest line, wide arcing motion Fix these and feel the difference on your next chest day. #chestworkout #pecdeckfly #gymmistakes #gymtips #GymTok
