Shiko is a traditional Japanese exercise commonly practiced in sumo wrestling. It involves a series of stomping movements where the wrestler raises one leg and brings it down forcefully, often while bending the knees. This action helps to strengthen the legs, improve balance, and enhance overall stability. In addition to its physical benefits, shiko also serves a cultural purpose in sumo rituals. Wrestlers perform shiko as part of their training and before matches to show respect to the ring, known as the dohyo. The exercise is deeply rooted in the history and traditions of sumo wrestling.
