Which of the following cues can improve the start position for Standing Chest Expansion?

To enhance the start position for Standing Chest Expansion, the cue to "reach the crown of the head to the ceiling" is particularly effective. This specific cue emphasizes the importance of aligning the spine and extending through the body, promoting an elongated posture. By reaching upward, practitioners are encouraged to create space between the vertebrae, which allows for better alignment of the head, neck, and shoulders. This not only helps to facilitate proper breathing and expansion of the chest but also improves overall stability and balance during the exercise.

While the other options can contribute to good posture and alignment, they don't directly target the fundamental aspect of establishing an extended and tall position that supports effective movement in Standing Chest Expansion. Drawing the shoulder blades together is more about engaging the upper back muscles, which can lead to a more compressed position rather than an elongated one. Hips back and chest forward focuses on lower body positioning, and putting weight in the heels can be beneficial for grounding but does not directly encourage the vertical extension of the body. Therefore, reaching the crown of the head to the ceiling stands out as the principal cue to optimize the start position for this exercise.
