Shiko [四股]

Shiko is one of the fundamental exercises in sumo. During this break in action, the Sumo Kyokai (Japanese Sumo Association) has been posting demonstrations of shiko from many top wrestlers. It is exercise #3 in the Kyokai’s list of “sumo taiso” exercises, and during the pandemic it is also an attempt to help people find exercises they can do at home. Yesterday’s post was of Kotonowaka.

My son has gone a bit soccer mad so we play in the backyard just about every day. My shooting has improved dramatically as this shot went around a tree and just caught the top corner. He thought it was going wide but just curved in. Despite my son’s protests, VAR upheld this goal.

Every few days I would tweak this one quad muscle that runs down the front of my thigh, and sometimes my groin. So I started doing shiko in the mornings and it actually seems to help stretch that rectus femoris muscle that I think had been giving me so many issues. I also think it helps to stretch my IT band because that does not hurt anymore when I run. The video below was the only one I could find that tried to mention the muscle groups involved. There’s also this entertaining post from the sumo forum. (From 2004! Pre-Abi, Pre-Endo.)
