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

Using a ball between the thighs is an effective strategy for a beginning student struggling with their centerline in The Hundred. The ball acts as a stabilizing tool that encourages the student to engage their inner thighs, which helps maintain alignment and reinforces a sense of connection to the center of the body. This connection is crucial for developing the awareness needed to support the position effectively throughout the exercise.

Incorporating the ball aids in achieving a more focused effort towards proper posture and alignment. It naturally encourages the activation of the pelvic floor and helps to facilitate the engagement of core muscles. As a result, the student can better identify their centerline and stabilize their movements, leading to improved execution of The Hundred.

The other props, while useful in different contexts, may not provide the same level of assistance for this specific challenge. Using a dynaband can add resistance, which might be too advanced for someone struggling with alignment. A flexcushion may be beneficial for providing support, yet it might not directly address the issue of maintaining the centerline in the same way the ball does. Similarly, placing a ball between the feet does not promote the same engagement of the inner thighs and may not help the student in achieving optimal alignment.
