Why is it important to perform the "Hundred" with straight legs?

Performing the "Hundred" with straight legs is significant primarily because it enhances the engagement of the abdominal muscles. By extending the legs, you create a longer lever, which increases the load on the core. This position requires more effort from the abdominal muscles to maintain stability and control throughout the exercise. The challenge of keeping the legs straight while pumping the arms also helps to activate not just the superficial abdominal muscles but also deeper core stabilizers, contributing to overall core strength and endurance.

The straight leg position also encourages proper alignment of the spine and pelvis, allowing practitioners to focus on engaging their abdominal section effectively without overly relying on other muscle groups. In addition, holding this position while maintaining breath control maximizes the benefits of the exercise, promoting coordination and increasing the intensity of the workout.
