💪 Lateral Raise Form Guide
Sculpt wider shoulders with precise lateral raises.
SportsReflector AI analyzes your lateral raise by tracking key body landmarks including shoulder, elbow, and wrist joints. We assess the angle of abduction at the shoulder, ensuring a controlled ascent and descent, and monitor elbow flexion to prevent biceps involvement. Metrics tracked include range of motion, tempo, and stability throughout the movement.

5 Lateral Raise Mistakes AI Catches
These are the most common Lateral Raise form errors — and the ones most likely to cause injury or limit your progress.
Using momentum from the hips or torso to lift the weights reduces the tension on the medial deltoids, transferring the load to the lower back and traps. This diminishes muscle activation and increases risk of lumbar strain.
Fix: Select a lighter weight. Initiate the movement purely from the shoulders, keeping the torso rigid. Focus on a controlled 2-second concentric phase and a 3-second eccentric phase.
Excessive elbow flexion (too bent) shortens the lever arm, making the exercise easier and reducing deltoid engagement. Locking out the elbows (too straight) places undue stress on the elbow joint and can lead to hyperextension injuries.
Fix: Maintain a slight bend in the elbows (approximately 10-20 degrees) throughout the entire movement. This creates an optimal lever arm for deltoid activation and protects the elbow joint.
Lifting the dumbbells significantly above shoulder height (beyond 90 degrees of abduction) causes the upper trapezius to take over, reducing medial deltoid isolation and potentially impinging the shoulder joint.
Fix: Stop the upward movement when your arms are roughly parallel to the floor, forming a 90-degree angle at the shoulder. Focus on feeling the contraction in the side of your shoulder, not your neck.
Allowing the wrists to internally rotate (thumbs pointing down) at the top of the movement can create impingement in the shoulder joint, especially with heavier weights, leading to pain and potential rotator cuff issues.
Fix: Keep your hands in a neutral or slightly externally rotated position (pinkies slightly higher than thumbs) at the top of the movement. Imagine pouring water out of a pitcher.
Elevating the shoulders towards the ears (shrugging) during the lift indicates that the upper trapezius muscles are compensating for weak deltoids or excessive weight. This reduces deltoid activation and can cause neck and upper back tension.
Fix: Actively depress your shoulders away from your ears before and during the lift. Focus on isolating the movement to the side deltoids. Lower the weight if you cannot maintain shoulder depression.
