Why is a mini-band placed above the knees during the modified side plank?

Placing a mini-band above the knees during the modified side plank is primarily intended to activate the hips' external rotators and abductors of the top leg. This strategic placement adds resistance, effectively engaging the muscles in the hip region, which are crucial for proper alignment and stability during the plank. The activation of these muscle groups helps enhance overall motion control and stability of the pelvis while performing the exercise.

Moreover, the resistance provided by the band requires the individual to engage their gluteus medius and minimus, essential muscles for hip stability and function. This not only contributes to improved performance of the side plank itself but also serves as a valuable foundation for other movements that rely on hip stability, ultimately improving overall functional strength and performance.

While other answers may touch on elements of strength or stability, they do not specifically address the focused activation of the hip muscles through the resistance of the mini-band, which is the essential aspect of this exercise variation.
