Rose Byrne’s outfits on ‘Physical’ transform her into an aerobics queen

How does an aerobics queen preen?

Rose Byrne had to look the part for her new Apple TV show “Physical,” in which she stars as Sheila, an unhappy 1980s housewife who transforms into an aerobics maven and lifestyle guru — long before influencers made that a regular thing.  Premiering Friday, June 18, the series takes place over the span of many years, opening in 1986 with a scene of Sheila in a dressing room rocking a bedazzled leotard at the peak of her success, before jumping back in time to her unsatisfying life with her husband in 1981 San Diego.
