We think about the fists but not as much about the other aspects, such as footwork and dodging.
When I think of waist in boxing, I think of Ali with his arms limp, leaning back just enough for his opponent's strikes to fall just short as a taunt. (Here's a less refined, but more humorous version.) Ali would also lean into long light jabs, and McGreggor's style of Irish pugilism seems to me exemplified by a strong, flexible waist and love of leaning. McGreggor and St-Pierre are adept at pummeling an opponent as they sink to the mat, which is at least as old as Pankration. Pacquiao is another example of using the waist to lean, and today you sometimes see fighters striking from extreme angles.

How much training goes into this?
