Single-Arm Leaning on Bench Lateral Raise with Dumbbell
Set up a flat or inclined bench. Lean your torso against the bench at about a 45 degree angle. Place one hand on the bench for support.
Hold a dumbbell in your free hand with an overhand grip. Let your arm hang straight down by your side with a slight bend in the elbow.
Keeping your elbow slightly bent, raise the dumbbell out to your side until your arm is parallel to the floor. Focus on lifting with your shoulder, not your elbow.
Pause briefly when your arm reaches parallel then slowly lower back to the starting position.
Keep your torso stationary throughout the movement. Do not swing or rock your body.
Squeeze your shoulder blades together as you lift the weight. This helps stabilize your shoulder joint.
Exhale as you perform the lifting motion. Inhale as you lower back down.
Complete all reps for one side before switching. You can rest the non-working hand on your hip or thigh for support.
Use a challenging but manageable weight. Start light and increase as you build strength.
