Lying One-Arm Lateral Raise

Muscles worked

Main muscles
- Anterior Deltoid
What it is
This isolation exercise strengthens your shoulder muscles, primarily targeting the lateral deltoids. You perform it lying face down on a flat bench, using a single dumbbell. This movement helps build definition and stability in the side of your shoulders.
Technique tips
- Use your free hand to grip the bench for added stability.
- Keep your elbow slightly bent throughout the movement.
- Raise the dumbbell until your elbow is level with your shoulder.
- Maintain your arm perpendicular to your torso as you lift.
- Hold the top contraction for a moment before lowering.
- Lower the weight slowly, controlling the movement against gravity.
How to track your progress
Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
