What kind of fitness training should a dancer do? And what would they need to improve?

Basically I'm doing a PEP for my GCSE coursework in PE..

and I'm a bit stuck..



So what types of training would a dancer have to do?

E.g. Fartlek training? Etc.



and what would they want to improve, cardiovasular fitness? stamina?



Thanks! :) xWhat kind of fitness training should a dancer do? And what would they need to improve?Lots of swimming,.
