• Warm Up Properly: Before performing Dumbbell Lying One Arm Deltoid Rear, complete 5-10 minutes of light cardio followed by dynamic stretches targeting the Delts and surrounding muscles.

• Shoulder Protection: Avoid flaring your elbows excessively, which can strain the shoulder joint. Keep your shoulders packed and stable.
• Respect Your Range of Motion: Work within your current mobility limits. Gradually improve flexibility over time rather than forcing deeper positions.
• Don't Hold Your Breath: Maintain consistent breathing throughout the exercise. Exhale during the exertion phase and inhale during the easier phase.
• Know When to Stop: End your set when you can no longer maintain proper form. Training to absolute failure on every set increases injury risk.
• Allow Adequate Recovery: The Delts typically need 48-72 hours to recover after intense training. Avoid training the same muscle group on consecutive days.
