What is the best prop for a beginning student struggling with their centerline in The Hundred?

Using a ball between the thighs is particularly beneficial for a beginning student struggling with their centerline in The Hundred because it promotes proper alignment and encourages engagement of the inner thigh muscles. This engagement helps the student find stability and maintain control over their body, which is crucial when working on core strength and coordination in Pilates exercises.

The ball acts as a tactile cue, allowing the student to feel the correct positioning of their legs while prompting them to maintain a strong centerline. By squeezing the ball, the student can enhance muscular activation in the pelvic region, which aids in achieving a more balanced and centered position throughout the movement. This prop provides both support and feedback, making it easier for the student to focus on their alignment and core engagement without the distraction of trying to stabilize their legs on their own.

Using other props, such as a dynaband, flexcushion, or placing a ball between the feet, may not offer the same level of support and guidance for a student specifically struggling with their centerline. While each of these props has its own merits in different contexts, the ball between the thighs is particularly effective for reinforcing the concept of centerline and stability in The Hundred.
