@synermuscle: Most people mess up the dumbbell fly without realizing it. Straight arms = shoulder stress, bicep strain, and less chest gains. This form mistake can wreck your joints and kill your progress. ✅ The fix? Keep a slight bend in your elbows, lower with control, and squeeze at the top. You’ll keep tension on your chest and finally feel the right burn. Train smart. Stay safe. Build real muscle. #SynerMuscle #ChestTraining #FixYourForm #FlyRight #InjuryFreeGains #3DTraining #GymTok #strength
