Bend your elbows at a 90-degree angle, positioning your upper arms parallel to the ground and your forearms perpendicular to it.
Keeping your upper arms stationary, extend your forearms backward until they are parallel with the floor, focusing on the contraction in your shoulder muscles.
Hold the position for a few seconds, feeling the tension in your shoulders.
Slowly return your arms to the starting position, maintaining control of the movement to ensure you're working your muscles and not relying on momentum.
