Any exercise that gets your heart beating faster and makes you out of breath is aerobic – the term is a technical one to do with the fact that your heart needs extra oxygen to help the muscles keep up. However, aerobics classes are a masochistic form of keep-fit, run by a special type of gym instructor who is bred for bossiness and intolerance and who has a particularly irritating voice. If you leave their classes without feeling as though you’ve gone five rounds with Mike Tyson and then been knocked over by a 4 × 4 on the way home, they’ll think they’ve failed. ‘No pain, no gain,’ said Jane Fonda, one of the original devotees, little knowing what she was starting.

For all this effort you’d expect a decent calorie-burning payoff, yet a two-hour aerobics class would barely deal with a large portion of Black Forest gateau (840 kcal), and leave no room at all for a skoosh of double cream on top (149 kcal).
