The exercise of walking with a side rubber looks (and seems) quite strange, but in fact it is an ideal way to improve hip stability, strengthen the hip abductor muscles, especially the middle gluteus muscle, and increase the stability of the knee joint. As part of the warm-up exercise, walking sideways involves many deep muscles that stabilize the pelvis. Doing this exercise before a workout can improve hip, foot, and ankle stability, as well as knee joint stabilization. This, in turn, improves the overall mechanics of the body and the effectiveness of movements during training or competition.
