常见错误
Excessive Momentum/Swinging
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.
Elbows Too Bent or Locked Out
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.
Raising Weights Too High
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.
