When I was playing college football, they would take the football team to a ballet school. We would learn to do tour jete's to prepare us when you are running in pursuit to tackle a ball carrier and you get hit, or somebody comes from another angle. This way you can spin away from the hit and your foot is out so you can go right into your run - basically, it pushed us toward the tackle. There's a good tweet: "Take ballet - it will push you towards the tackle."
