As the music throbbed, 1,000 inmates at Lima’s notorious Luriganco prison donned lycra in an attempt to break the world record for the largest number of prisoners to take part in an aerobics workout.
The jailbirds were put through their paces by a group of instructors.
The workout – not breakout – lasted for three hours .
Their hard labour was not in vain as the world record was monitored by a Peruvian lawyer.
The prisoners now await the verdict of the official Guinness World Record judges.
