Engage your core and maintain an upright posture. Keep arms straight with a slight bend in the elbows as you lift forward and upward to shoulder height. Briefly pause at the top to contract your deltoids, then slowly lower arms, resisting band tension.
Focus on keeping your shoulders down and away from your ears to prevent upper trap tension and ensure the movement originates from your deltoids. Actively tighten your core muscles throughout the exercise to stabilize your spine and transfer power efficiently. Maintain a slight bend in your elbows to avoid hyperextension and protect your joints. Perform a controlled lift, focusing on feeling the contraction in your shoulder muscles, rather than relying on momentum. Avoid using momentum to swing the band, as this reduces the effectiveness of the exercise and can lead to injury.
