Wow, that was so informative and interesting to watch. I had no idea that’s how it works to qualify for the olympics. Thank you very much for posting this and explaining it. I was happy to hear that Japan won the gold medal today. This video provides a lot of context for the work they put in to create that result. I work for orthopedics and for low back pain, our docs sometimes recommend a sacroiliac compression belt (SI brace), because low back pain can surprisingly actually originate from your sacrum, not your back. When you don’t have a SI compression belt, lying on your back with your sacrum/upper butt on a yoga block (bring your knees up, knees bent) can also help to put flat, even pressure on your sacrum. Not sure if that was his issue, but it could be worth asking your orthopedic surgeon if an SI Brace for the sacrum (sacroiliac joint) is something they would recommend.
