How to do the Dumbbell Side-Lying Single-Arm Bench Press
A dumbbell (choose a weight that you can lift comfortably for multiple repetitions)
1. Positioning:
Lie on your side on a flat bench with your body aligned straight from head to toe. Your hips should be against the bench.

Hold the dumbbell in your top hand. Your elbow should be bent at about a 90-degree angle with the dumbbell near your chest.
Starting Position:
Keep your knees slightly bent and stacked on top of each other or one leg slightly ahead for extra balance.
Ensure your feet are firmly placed on the ground and your core is engaged.
Movement:
Press the dumbbell upward by extending your arm while keeping it straight above your shoulder.
Exhale as you push the dumbbell up. Make sure your wrist is straight and aligned with your forearm throughout the movement.
Lower the dumbbell back to the starting position near your chest, inhaling as you do so.
Repetitions:

Keep your body stable and minimize any rotation at your torso.
