Lateral Neck Flexion
The range of motion of lateral neck flexion is about 40 degrees from neutral, any further movement is usually equated with movement of the shoulders. When starting the exercise the face pad should apply pressure to the neck so the musculature is under tension before the first repetition is initiated. A coaching cue during the exercise to help level the shoulders is have the athlete keep his or her eyes looking straight ahead to aid in maintaining the appropriate posture.
Neck lateral flexion can also be done by beginning with the ear close to the acromioclavicular joint and then advance the face pad to a neutral position followed by a pause. Both movements effectively train the neck. Periodically varying the starting position in a training regime will help in Getting Strong.
