Aidan Smith's TV week: Aerobics revived in Physical (Apple TV+), social undistancing in Too Hot to Handle (Netflix) and the finale of the brilliant Time (BBC1) Remember the aerobics boom? I was there. Three classes a week of feeling the burn to the Hi-NRG beats of Donna Summer and Hazell Dean, although never “Physical” by Olivia Newton-John - what a cash-in track! - and never in spandex or leg-warmers, although there may have been some headband action.
