Which of the following best describes the term 'horizontal adduction'?

The term 'horizontal adduction' refers specifically to the movement of the arms towards the midline of the body while maintaining a horizontal position parallel to the ground. This movement occurs primarily at the shoulder joint and typically involves bringing the arms close together in front of the body.

Understanding 'horizontal adduction' is crucial for instructors guiding their clients through exercises that involve bringing the arms together, such as in chest flys or bench press movements. It is a foundational concept in kinesiology and exercise science, allowing for a clearer understanding of how to perform movements correctly and safely.

The other options describe different types of movements, such as abduction (moving away), rotational movement, and leg movements, which do not accurately characterize horizontal adduction. Therefore, option B is the best choice that accurately captures the essence of horizontal adduction.
