Which of the following exercises helps improve balance while also stretching the spine and thighs?

The exercise that helps improve balance while also stretching the spine and thighs is Rocking. This exercise engages the core while mobilizing the spine and allows for a deep stretch in the front of the body, particularly in the thigh area. As practitioners perform the Rocking exercise, they must find stability and balance through their central axis, building strength in the lower back and enhancing coordination. The rhythmic nature of the movement also encourages a flowing quality that promotes body awareness and control.

This combination of stretching while focusing on balance makes Rocking an excellent choice for improving overall stability and flexibility. The movement challenges the participant to maintain alignment while in motion, which further contributes to the benefits of balance and core stability. Other exercises such as Swan, Swimming, and Grasshopper might focus on different muscle groups or movements that do not emphasize both balance and the same stretch of the spine and thighs in the same way.
