Some "traditional" dances are definitely fitness oriented. Like this winning performance for world championship for the dragon dance. (which has 2 people underneath that hot costume...)

Or Highland dancing, tap dancing or some of the dance numbers from the Carribbean.
We might tend to be unaware with all the costumes or not sitting up close to see the physical effort.
