Buiding a ballet dancer's foot

The Salt Lake Tribune has a fascinating article talking about what it takes for a ballerina to be able to dance en pointe. There is emphasis on how ballet has become more athletic with time, and the cross-training that both men and women need to withstand the rigors of their art. This applies not just to ballet, but to ballroom dance as well, as champion ballroom dancers are world class athletes in their own right.
