During 'Corkscrew,' what should be done to prevent strain on the hip flexors?

To prevent strain on the hip flexors during the 'Corkscrew' exercise, bending the knees if necessary is a key modification. This adjustment allows for a more controlled movement and reduces the load on the hip flexors, which can become engaged excessively when the legs are straight and raised high. By bending the knees, the exercise can be performed with greater ease and alignment, enabling the core muscles to engage effectively while ensuring the hip flexors are not overextended or strained.

The emphasis is on maintaining a neutral pelvis and engaging the abdominal muscles throughout the movement, which can be easier to achieve when the knees are bent. This helps maintain proper form and prevents unnecessary tension in the hip flexors, allowing practitioners to focus on the controlled rotation and stability of the movement without risking injury.
