Sit upright on a bench and hold a pair of dumbbells just outside shoulder-width apart (Palms facing forward) and elbows flexed to your sides.
2. Raise the dumbbells vertically by extending your arms overhead and pressing through your palms while keeping your forearms perpendicular to the ground (This is the starting position).
3. Once your arms are fully extended, slowly lower only one dumbbell and after a brief pause, extend your arm and raise the dumbbell back to the starting position and repeat the steps with the other arm.
