Shriver’s contentious views on diversity thread through the story of a couple’s strained relationship with exercise

Lionel Shriver’s scabrously funny 15th novel presents a dyspeptic view of people in thrall to exercise. In 2013 Shriver’s own daily regime involved “130 press-ups, 200 side crunches, 500 sit-ups and 3,000 star jumps … The jumps take 32½ minutes, or three every two seconds”. The Motion Of The Body Through Space was written, she recently revealed, after she realised that she may be more dedicated to her exercise than to her writing.

The protagonist, Serenata Terpsichore (“rhymes with chicory”), is a 60-year-old woman from upstate New York with a beguiling voice and ruined knees. The former she puts to lucrative use as a voiceover artist and narrator of audiobooks. The latter are the result of a lifetime’s adherence to the doctrine of working out; in particular the belief that 10-mile runs are the key to longevity and good health.
