I'm not really sure what's happening here. But, I do know that this is a local Twin Falls Karate group and they're warming up.

Twin Falls Shotokan Karate shared this recently on YouTube. It's simply titled "Warmup". One of the younger members walks across the legs of the others.

My knowledge of karate begins and ends with Chuck Norris and "The Karate Kid" (the 1984 version). This is my perception of karate warmups.

Wax on. Wax off. Done.

Kudos to the Twin Falls Shotokan Karate group for taking this to the next level.
