The gym where Rebecca Roberts trains is in an unremarkable industrial unit in St Helens, Merseyside. The room is small, the ceiling low, the music driving, the equipment incongruously large.
There are the 115kg (253lb) logs she presses over her head and the atlas stones she heaves on to plinths. The heaviest stone she has lifted is 180kg. There are the frames she uses to practise hauling cars, whether a Ford Fiesta or her Honda CR-V. There are the barbells she loads with weights until they are heavy enough for her deadlifts. Her record is 300kg.
