In that telegraph article she (it?) seems to imply that you can do cheerleading, ballet, gymastics without working up a sweat.
That's nonsense surely? And if you aren't getting sweaty then it's not great exercise surely?
Maybe she looks at the people on the telly who've been doing it for years and are like the most super-athletic people they are and thinking "oh well they don't look sweaty, obviously this is a sport you can do vigorously and not sweat". I am utterly
TBH.
